The Bosch 800 Series SHX78DM5N is a premium 24-inch built-in dishwasher that combines several of Bosch’s most advanced residential dishwasher technologies, including CrystalDry, PrecisionWash, a Flexible 3rd Rack, RackMatic, Home Connect, AquaStop, a stainless-steel tub, and a 42 dBA noise rating. Unlike some older Bosch 800 Series models, the SHX78DM5N is part of a newer generation that specifically emphasizes improved drying performance, including better drying of dishwasher-safe plastics.
The model is available in both the United States and Canada, although regional pricing, finish terminology, installation requirements, warranty details and availability can differ. The U.S. product information identifies it as a 24-inch stainless-steel anti-fingerprint dishwasher, while the Canadian product information lists a brushed-steel anti-fingerprint finish. The underlying model number remains SHX78DM5N.
One of the most important characteristics of the SHX78DM5N is that it is not simply a quiet dishwasher with a third rack. Its design combines mechanical washing technology, sensor-controlled cycles, Zeolite-based CrystalDry drying, adjustable racks and connected controls. The operating manual also documents AquaSensor operation, multiple wash programs, sanitation, Home Connect functions and detailed maintenance procedures.
This makes the SHX78DM5N particularly interesting for households that want strong drying performance as well as cleaning performance. The presence of CrystalDry is especially significant because plastics are traditionally among the more difficult dishwasher-safe items to dry completely. Bosch states that its CrystalDry system uses natural minerals to transform stored moisture into heat and can make dishes, including plastics, up to 60% drier compared with its PureDry technology, although actual results vary according to dish type.

What Is the Bosch SHX78DM5N?
The SHX78DM5N is a 24-inch Bosch 800 Series top-control dishwasher designed for full-size residential kitchens. Its controls are positioned at the top edge of the door, allowing the front of the dishwasher to maintain a relatively clean appearance when the door is closed. Bosch lists the appliance at 33 7/8 inches high, 23 9/16 inches wide and 23 3/4 inches deep.
The dishwasher is designed around a conventional 24-inch cabinet opening, with Bosch specifying a required cutout of 33 7/8 inches high, 24 inches wide and 24 inches deep. Because cabinetry, flooring and countertop construction can affect the actual available opening, the installation documentation should be checked before final installation rather than relying only on the appliance’s headline dimensions.
The machine has a stainless-steel tub, anti-fingerprint stainless-steel exterior, a Flexible 3rd Rack, RackMatic upper-rack adjustment, PrecisionWash, CrystalDry, Home Connect and AquaStop. These features put the model firmly into Bosch’s premium dishwasher range.
Design and Exterior
The SHX78DM5N uses an anti-fingerprint stainless-steel finish, which is intended to reduce visible smudges compared with conventional stainless-steel surfaces. The Canadian specification describes the finish as brushed steel anti-fingerprint, while the U.S. description identifies stainless steel anti-fingerprint.
The top-control design is useful for people who prefer a clean appliance front. When the door is closed, the controls are hidden rather than displayed prominently across the exterior. The model also uses InfoLight, which projects a light onto the floor to indicate that the dishwasher is operating.
The stainless-steel tub is another important part of the construction. Stainless steel provides a durable interior surface and is commonly used in premium dishwashers because it tolerates repeated exposure to water, detergent and elevated temperatures. The SHX78DM5N’s official specification specifically lists a stainless-steel tub.
16-Place-Setting Capacity
The SHX78DM5N is rated for 16 place settings, giving it substantial capacity for family households and larger dinner loads.
Capacity is not determined by the number of place settings alone. Rack geometry is equally important because a dishwasher can have a large theoretical capacity but still be difficult to load if the racks do not accommodate different dish shapes.
The SHX78DM5N addresses this with three levels of loading space: the lower rack, adjustable upper rack and Flexible 3rd Rack. The third rack is especially useful because utensils and smaller items can be moved away from the main racks, leaving more usable space for plates, bowls and cookware.
For a family that runs the dishwasher once a day, the 16-place-setting capacity can reduce the temptation to run partially filled cycles. Correct loading remains important, however, because overcrowding can prevent spray jets from reaching dish surfaces. The operating manual specifically identifies tightly packed dishes, blocked spray arms and incorrect loading as possible causes of food remaining on dishes.
Flexible 3rd Rack
The Flexible 3rd Rack is one of the most useful features on the SHX78DM5N. Bosch states that its fold-down sides add approximately 30% more loading area compared with a Bosch dishwasher with two racks. It is designed particularly for utensils and ramekins.
The flexibility comes from being able to change the configuration of the rack depending on what needs to be washed. Long utensils can occupy the upper level while the lower racks remain available for larger dishes.
The operating manual also describes a reorganizable silverware drawer with fold-down side shelves and front tines, allowing more space for longer or wider cutlery. This makes the third rack more than a simple flat tray for knives and forks.
For everyday use, the third rack can make a noticeable difference because it moves small objects out of the lower basket. This can make the lower rack easier to organize around plates, cookware and larger serving dishes.
RackMatic Adjustable Upper Rack
The SHX78DM5N includes RackMatic, allowing the upper rack to be adjusted vertically. The operating manual explains that the rack can be raised or lowered using the side levers and should be adjusted evenly on both sides.
This is important because dishwasher loads change constantly. A normal evening load might contain plates and bowls, while a weekend load may include tall glasses, large cookware or unusually shaped serving dishes.
Raising or lowering the upper rack changes the vertical clearance available between the racks. This allows users to prioritize tall items either above or below depending on the load.
The system therefore contributes to the dishwasher’s practical capacity. Rather than having one fixed rack arrangement, the user can modify the interior according to the dishes being washed.
PrecisionWash Cleaning System
The SHX78DM5N uses PrecisionWash, Bosch’s multi-level washing system. The official specification identifies PrecisionWash and a five-level wash system.
The underlying concept is straightforward: water needs to reach the surfaces of dishes from multiple directions. Spray-arm coverage, water pressure, detergent and appropriate loading all contribute to cleaning.
The operating manual identifies upper and lower spray arms and specifically advises cleaning them if dishes are not being washed properly. It also explains that the spray jets need sufficient access to dish surfaces and that blocked spray-arm rotation can reduce cleaning performance.
This means PrecisionWash should not be interpreted as a system that makes loading irrelevant. The dishwasher can deliver sophisticated water distribution, but dishes still need to be positioned so that water can reach them.
How Good Is the Cleaning Performance?
The SHX78DM5N has the hardware expected from a premium dishwasher: PrecisionWash, five-level washing, sensor-controlled Auto operation, a Heavy cycle, stainless-steel construction and adjustable racks.
The Heavy cycle is intended for pots, pans, non-fragile dishes and silverware with stubborn baked-on or dried food. The manual specifies cleaning temperatures in the approximately 151–160°F range during the intensive portion of this program.
The Auto cycle is designed for mixed dishware and silverware with ordinary household food remnants. Its operation is sensor-controlled according to the soiling level detected in the wash water, with the machine adjusting the cycle accordingly.
This sensor-based approach can be useful for everyday loads because not every dishwasher load needs the same amount of washing time or water. A lightly soiled load does not necessarily require the same treatment as a casserole dish covered in baked-on food.
AquaSensor and Automatic Cleaning Adjustment
The SHX78DM5N’s operating manual describes an AquaSensor that measures the turbidity of the wash water using an optical system. When the water is relatively clean, the dishwasher can reuse it during a subsequent rinse; when the soil level is higher, the machine drains the water and replaces it.
In Auto cycles, the sensors can also influence temperature and run time according to the detected soil level. This gives the dishwasher a way to adapt the wash process rather than treating every load identically.
Sensor-controlled washing is particularly useful for households where loads vary substantially. A load of lightly used plates and glasses may require very different treatment from a load containing dried sauces, oatmeal, grease or baked-on food.
Wash Cycles
The SHX78DM5N has five cycles directly available through the control panel:
- Heavy
- Auto
- Normal
- Speed60
- Favorite
Bosch also documents additional cycles available through Home Connect:
- Delicate
- Rinse
- MachineCare
The actual operating time and consumption can vary according to water temperature, dish quantity, soil level and selected options.
The Heavy cycle is designed for more difficult loads, while Auto is intended to adapt to soil conditions. Normal is described as the most economical cycle, and Speed60 is designed around a one-hour wash for suitable loads.
The Favorite function is particularly useful for users who repeatedly use the same combination of cycle and option. The manual explains that a preferred combination can be saved and accessed again, with Home Connect providing additional customization possibilities.
Speed60 Cycle
Speed60 is intended for situations where dishes need to be washed and dried more quickly. The manual lists a one-hour duration under its specified test conditions and describes it as a time-optimized cycle for mixed dishware with ordinary food remnants.
A one-hour cycle is useful when the dishwasher needs to turn around a load quickly, such as after a dinner party or during a busy day when dishes need to be reused.
However, the shortest cycle should not automatically be used for heavily baked-on food. The manual’s descriptions indicate that Heavy is the appropriate choice for stubborn burned or dried-on food, while Speed60 is intended for lighter everyday soil.
Normal Cycle and Energy Efficiency
The Normal cycle is identified in the operating manual as the most economical cycle under the documented operating conditions. Its specified consumption range is approximately 0.780–0.850 kWh and 2.3–5.5 gallons of water, depending on the relevant operating conditions.
The variation is important because dishwasher consumption is not always one fixed number. Sensor behavior, incoming water conditions, soil level and other factors can affect actual consumption.
For regular household loads, Normal is therefore an important program for users who want to balance cleaning performance with resource consumption.
CrystalDry: The Major Feature
The defining feature of this particular Bosch 800 Series dishwasher is CrystalDry.
The SHX78DM5N uses Zeolite mineral technology to assist the drying process. The operating manual explains that Zeolite stores moisture and energy and then releases heat during the drying phase. Moisture is absorbed into the mineral and heat is released into the dishwasher interior with dry air.
This is fundamentally different from simply relying on residual heat from the wash water. The mineral-based system is designed specifically to improve drying while also supporting energy efficiency.
The official specification states that CrystalDry can make dishes, including plastics, up to 60% drier compared with Bosch dishwashers using PureDry, based on Bosch’s aggregate testing and subject to variation according to dish type.
Why CrystalDry Matters for Plastics
Plastic containers are among the most frustrating items to dry in many dishwashers because they do not retain heat as well as glass, ceramic or metal.
The SHX78DM5N specifically addresses this issue with CrystalDry. Bosch’s documentation describes the Zeolite system as producing heat up to 176°F/80°C and says that it is designed to thoroughly dry dishes and dishwasher-safe plastics.
That does not mean every plastic object will emerge completely dry under every loading arrangement. Shape, material, orientation and water trapped in recesses can still affect drying.
The operating manual itself notes that water can collect in recesses and recommends positioning dishware at an angle where possible. It also recommends rinse aid for optimum drying results.
Does CrystalDry Use Zeolite?
Yes. The operating manual specifically identifies a Zeolite container and explains its role in the drying process. Zeolite absorbs moisture during drying and releases heat, which is then circulated into the dishwasher interior.
The manual also warns users not to position dishes directly in front of the Zeolite intake or outlet openings because doing so can impair drying performance. Heat-sensitive items should also not be positioned directly in front of the outlet.
This means loading technique can influence how effectively CrystalDry works. The technology is sophisticated, but the airflow path still needs to remain functional.
CrystalDry vs Traditional Heated Drying
Traditional heated drying primarily relies on heat generated during the dishwasher cycle and, depending on the design, an electric heating element.
The SHX78DM5N still has a concealed water-heating element, but its drying system adds Zeolite-based moisture absorption and heat release. This gives the dishwasher an additional mechanism for transferring moisture away from dishes.
The practical difference is most noticeable when drying difficult items such as plastics. Glass and ceramic generally dry more easily because they retain heat better and have different surface characteristics.
For households that regularly wash reusable plastic containers, CrystalDry is therefore one of the most meaningful reasons to consider this model.
Sanitize Option
The SHX78DM5N includes a Sanitize option. Bosch identifies it as an NSF-certified sanitation option and explains that it increases temperature and cycle length to achieve sanitation.
The option can be useful for items such as chopping boards and baby bottles when those items are dishwasher-safe and the manufacturer’s instructions permit dishwasher cleaning.
It is important not to interpret the presence of a sanitize option as meaning that every cycle sanitizes dishes. The operating manual explicitly states that only sanitizing cycles are designed to meet the applicable soil-removal and sanitation efficacy requirements.
42 dBA Noise Level
The SHX78DM5N is rated at 42 dBA, which is one of its strongest comfort features.
A low noise rating is particularly valuable in open-plan kitchens where the dishwasher is located near living rooms, dining areas or home offices.
However, a laboratory-style sound rating should not be interpreted as meaning that the dishwasher produces absolutely no audible sound. Pumps, water movement, draining, spray-arm operation and dishes contacting one another can still be heard.
Installation can also influence perceived noise. Cabinet construction and the surrounding kitchen environment can affect how much sound reaches the room.
Is 42 dBA Really Quiet?
For a residential dishwasher, 42 dBA represents a quiet operating specification.
The official product information emphasizes the 42 dBA rating and markets the dishwasher around quiet operation.
This is especially relevant if you run the dishwasher at night or while people are eating nearby. Users may still hear some mechanical sounds, but the low rated sound level is designed to minimize disruption.
For an open-concept home, noise can therefore be almost as important as cleaning performance, particularly if the dishwasher is run frequently.
Home Connect and Wi-Fi
The SHX78DM5N is Wi-Fi enabled and compatible with Home Connect.
The operating manual documents Home Connect functions including app setup, Remote Start, Remote Diagnostics, software updates and data-protection information.
Connected functionality also expands the number of available wash cycles and options. The specification lists three additional cycles through Home Connect—Delicate, Rinse and MachineCare—and two additional options, Half Load and Eco.
This is useful because the physical control panel does not necessarily expose every possible cycle or option. Home Connect effectively extends the dishwasher’s control interface.
Smart Cycle and Favorite
The SHX78DM5N includes a Favorite function that allows users to save a preferred cycle and option combination. Bosch also states that Home Connect can provide access to additional wash cycles and options and can assist users in selecting appropriate settings.
For someone who repeatedly uses the same combination—for example, Normal plus CrystalDry—the Favorite function can reduce the number of button presses required.
The value of this feature is less about novelty and more about convenience. A dishwasher that is used almost every day benefits from simple controls for repetitive tasks.
Does Home Connect Replace the Physical Controls?
No. The SHX78DM5N still has physical controls for its primary cycles and options. Home Connect supplements those controls with connected functions and additional cycles and options.
This is useful for households that do not want to depend entirely on an app. Basic dishwasher operation remains available directly at the appliance.
The connected system becomes an additional layer for remote operation, diagnostics, updates and expanded settings.
AquaStop Leak Protection
The SHX78DM5N includes 24/7 AquaStop leak protection.
Leak protection is particularly important with built-in dishwashers because the appliance connects to a household water supply and sits within cabinetry.
AquaStop should not be interpreted as an absolute guarantee that water damage can never occur. Correct installation, proper hose connections and regular inspection remain important.
The model’s support documentation also emphasizes using appropriate installation procedures and qualified service for repairs.
Water Softener: An Important Limitation
One specification that potential buyers should notice is that the SHX78DM5N does not have a built-in water softener according to the model specification.
This matters particularly in hard-water areas.
Hard water can contribute to mineral deposits, spotting and scale. While rinse aid and appropriate detergent practices can help, the absence of an internal water-softening system means that households with particularly hard water may need to pay more attention to detergent selection, rinse aid, maintenance and the condition of their incoming water.
This is a meaningful difference from some other Bosch dishwasher configurations that include a water softener.
Water Consumption
Bosch specifies water consumption of 3.2 gallons per cycle for the SHX78DM5N and lists annual energy consumption at 240 kWh. The model is identified as ENERGY STAR certified in its specification.
The current ENERGY STAR criteria for standard residential dishwashers allow a maximum of 3.2 gallons per cycle and 240 kWh per year. Those criteria became effective July 19, 2023.
The SHX78DM5N therefore sits directly at the current maximum thresholds stated in its specification rather than being below both limits.
Actual household consumption can differ from the annual figure because usage depends on cycle selection, number of cycles and operating conditions. The manual also provides cycle-specific consumption ranges rather than implying that every cycle uses the same amount of water and electricity.
Energy Efficiency
The SHX78DM5N is ENERGY STAR certified and has a listed annual energy consumption of 240 kWh.
The current certification criteria establish 240 kWh/year as the maximum energy consumption for a standard-size qualified dishwasher.
The dishwasher’s energy performance is helped by several design elements. The operating manual specifically describes Zeolite drying as an energy-saving technology and explains how moisture is stored by the mineral and heat is released during the drying stage.
The Normal cycle is also identified as the most economical cycle in the model’s operating documentation.
Installation Dimensions
The SHX78DM5N measures:
- 33 7/8 inches high
- 23 9/16 inches wide
- 23 3/4 inches deep
Bosch specifies a required cutout of:
- 33 7/8 inches high
- 24 inches wide
- 24 inches deep
The appliance has adjustable feet and a net weight of approximately 96 pounds.
These dimensions make the model a conventional full-size 24-inch dishwasher rather than an ADA-height model. Anyone replacing an existing dishwasher should measure the actual opening before ordering.
Countertops, flooring and cabinet construction can affect the usable height, so the final installation instructions should always take precedence over a general product dimension.
Electrical Requirements
The SHX78DM5N is specified for 120 volts, 60 Hz and 12 amps, with a rated power of 1,440 watts.
This is important for international readers.
The exact SHX78DM5N is a North American electrical model. Therefore, although the dishwasher can be evaluated conceptually by readers in the UK, the exact U.S./Canadian model should not be treated as a standard UK appliance installation. A UK kitchen normally requires a dishwasher configured for the local electrical system and installation requirements.
For USA and Canada buyers, the documented electrical specification is appropriate to the North American market, subject to the applicable local electrical code and installation instructions.
Minimum Water Pressure
The model-specific specification lists a minimum water pressure of 14 psi.
Water pressure matters because dishwasher filling and spray performance depend on an adequate water supply.
The operating manual also notes that water pressure can influence actual cycle consumption and operation. If a dishwasher repeatedly shows water-inlet problems, checking the household water supply and inlet arrangement can therefore be an important diagnostic step.
Dishwasher Cycles and Real-World Use
The SHX78DM5N’s five primary cycles provide a useful range without requiring the user to rely on the app for basic operation.
Heavy is intended for stubborn, baked-on food.
Auto uses sensor information to adjust operation based on soil conditions.
Normal is intended for ordinary mixed loads and is identified as the most economical cycle.
Speed60 provides a one-hour time-oriented program for appropriate loads.
Favorite allows a saved cycle-and-option combination.
Additional Home Connect cycles include Delicate, Rinse and MachineCare.
Heavy Cycle Performance
The Heavy program is designed for pots, pans and non-fragile dishware with stubborn burned or dried-on food. The manual lists an intensive cleaning temperature range of approximately 151–160°F.
This makes Heavy the logical choice for casserole dishes, heavily soiled cookware and loads where food has dried onto the surface.
The program takes considerably longer and consumes more resources than the quickest cycles, but that is expected when the machine has to remove difficult soil.
Users should still scrape large food remnants from dishes before loading. The goal is to remove loose food without unnecessarily pre-rinsing the entire dish.
Auto Cycle
Auto is designed for mixed dishware and silverware with common household food remnants. The machine uses sensor information from the wash water to adjust the cycle according to soil conditions.
This makes Auto particularly suitable for households where load conditions vary.
Instead of deciding manually whether a load requires a more intensive wash, the dishwasher can use its sensors to make adjustments.
The effectiveness of sensor-based operation still depends on sensible loading. The manual warns that excessive pre-rinsing can actually cause sensors to select a lighter cycle, potentially leaving stubborn remnants behind.
Normal Cycle
Normal is intended for ordinary mixed loads and is described as the most economical cycle in the manual. It uses a lower cleaning temperature range than Heavy and includes washing, intermediate rinsing, final rinsing and drying.
For households that run the dishwasher regularly, Normal is likely to be the main everyday program.
Using the appropriate cycle is important for efficiency. Not every load needs the longest or hottest program, while heavily baked-on food may require more intensive treatment.
MachineCare Cycle
MachineCare is available through Home Connect according to the SHX78DM5N specification.
A dedicated machine-maintenance program can be useful because dishwasher interiors can accumulate mineral deposits, detergent residue and other buildup over time.
The operating manual also provides separate cleaning instructions for the tub, filters and spray arms. Therefore, MachineCare should be considered part of a broader maintenance routine rather than a replacement for manual filter and spray-arm cleaning.
Rinse Cycle
Rinse is one of the additional cycles available through Home Connect.
A rinse cycle can be useful when dishes need to be held before a full wash or when a user wants to rinse off residue without immediately running a complete cleaning program.
Its usefulness depends on the household’s routine. Users should not confuse a rinse cycle with a full cleaning cycle.
Rinse Aid and Drying
The operating manual explicitly recommends rinse aid for optimum drying results.
Rinse aid helps reduce the tendency of water to remain as droplets on dish surfaces. This is especially useful when drying glassware, metal items and other surfaces where water spots can become visible.
If dishes are not drying properly, the manual identifies insufficient rinse aid, poor rinse-aid performance, incorrect loading, insufficient drying time and certain cycle settings as possible factors.
Therefore, even though CrystalDry is a major drying technology, rinse aid remains relevant.
Hard Water Performance
The lack of a built-in water softener is worth considering in regions with hard water.
Hard water can create white mineral deposits and spots, particularly on glassware.
If you live in an area with hard water, appropriate detergent dosage, rinse aid and regular dishwasher maintenance become more important. The actual water hardness of the home should be considered rather than assuming that all municipal water has the same mineral content.
The SHX78DM5N can still operate in hard-water areas, but users should understand that this model does not provide an internal water-softening system.
Filter and Spray Arm Maintenance
The SHX78DM5N has a filter system and removable spray-arm components that need periodic attention. The operating manual contains specific instructions for cleaning the filter system and spray arms.
Dirty filters can reduce cleaning performance because food particles and debris can interfere with the dishwasher’s water circulation.
The manual specifically lists dirty filters and blocked spray-arm nozzles as possible causes of food remaining on dishes.
This is an important maintenance lesson: premium dishwasher technology cannot compensate indefinitely for neglected filters and blocked spray arms.
Common Cleaning Problems
If food remains on dishes, the manual identifies several possible causes.
Dishes may have been loaded too closely together, spray-arm rotation may be blocked, spray-arm nozzles may be clogged, filters may be dirty, or the selected cycle may be too light for the soil level.
This means that poor cleaning does not automatically indicate a failed pump or defective dishwasher.
Before requesting service, users can inspect loading, filter cleanliness, spray-arm movement and cycle selection.
If the problem persists after these checks, professional diagnosis may be appropriate.
Common Drying Problems
The SHX78DM5N’s CrystalDry system is designed to provide strong drying, but drying problems can still occur.
The operating manual lists several possible causes of wet dishes, including insufficient rinse aid, unsuitable cycle selection, water collecting in recesses, dishes being removed too early, detergent performance and certain option settings.
Plastic containers can also retain droplets in corners and recessed areas because their geometry can trap water.
Correct loading is therefore important even with CrystalDry. Items should be positioned so that water can drain rather than remain trapped in deep cavities.
Why the Dishwasher Interior May Still Be Wet
A common misconception is that a premium dishwasher should have a completely dry interior after every cycle.
The SHX78DM5N manual explains that condensation can leave water droplets on the interior walls and that this is not necessarily an error. Moisture can condense on the inner walls and run down into the drainage system.
This distinction is important when evaluating the dishwasher. The goal of the drying system is to dry the dishware, not necessarily to leave every internal surface completely free of moisture.
Detergent Performance
The SHX78DM5N is designed for household dishwasher detergents and rinse aids. The manual provides separate guidance for detergent selection, incompatible detergents, detergent dosage and detergent placement.
Detergent performance can influence cleaning and residue.
The manual notes that old or clumped detergent may lose cleaning or dissolving performance and that detergent tabs may not dissolve completely in some short cycles.
For best results, detergent should be stored correctly and the selected cycle should be appropriate for the type of detergent being used.
Loading the Dishwasher Correctly
Correct loading is one of the most important factors in getting consistent results.
The operating manual recommends arranging dishes with enough space between them so spray jets can reach their surfaces. It also warns against blocking spray-arm rotation.
Tall narrow containers can require special attention because their shape can prevent water from reaching all internal surfaces.
Plates, bowls, glasses and cookware should therefore be positioned with water access in mind rather than simply trying to maximize the number of objects in the machine.
Plastic Items
Only plastic items specifically marked dishwasher-safe should be placed in the dishwasher. The operating manual explicitly warns against washing plastics that are not identified as dishwasher safe.
For dishwasher-safe plastics, the SHX78DM5N’s CrystalDry system is particularly relevant because Bosch designed the technology to improve drying performance on plastics.
However, plastic shape remains important. Containers with deep recesses can retain water even when the overall drying performance is excellent.
Stainless-Steel Interior
The stainless-steel tub is a major part of the SHX78DM5N’s premium construction.
A stainless-steel interior is exposed to detergent, water and heat every time the dishwasher operates, so correct detergent use and maintenance remain important.
The manual advises against harsh chlorine or bleach-based cleaning products and abrasive cleaning methods because these can damage the appliance.
Anti-Fingerprint Finish
The exterior is designed with an anti-fingerprint finish.
This can be useful in busy kitchens where the dishwasher door is opened and closed multiple times each day.
However, the finish still needs appropriate cleaning. The manual warns against abrasive sponges and unsuitable stainless-steel polishing products on anti-fingerprint surfaces.
Warranty
For U.S. appliances, the published warranty information identifies a one-year limited warranty covering the entire appliance, parts and labor. It also identifies additional limited coverage for certain electronics and racks from years two through five, and lifetime limited coverage for specified rust-through conditions on the inner tub liner and stainless-steel door, subject to the warranty terms.
The exact warranty terms should still be checked against the warranty documentation supplied with the particular appliance, especially for Canadian purchases or appliances purchased through different channels.
Warranty coverage is not the same as guaranteed reliability. A warranty describes what is covered if an eligible problem occurs; it does not establish how long every dishwasher will operate without repair.
Service and Parts Support
Model-specific support is available for the SHX78DM5N, including manuals, installation documentation, product specifications, energy information, replacement-part access and troubleshooting resources. Support pages also exist for multiple model variants such as /01 and /37.
This is useful for owners because the exact suffix can matter when ordering parts or consulting technical documentation.
The manufacturer’s support system also provides access to troubleshooting, error-code information, cleaning guidance and service resources.
For repairs involving electrical or water-related components, the operating documentation recommends appropriate qualified service rather than improvised repairs.
USA, Canada and UK Considerations
United States
The SHX78DM5N is documented as a 120 V, 60 Hz dishwasher with a 24-inch installation envelope. The U.S. product page currently lists the model as a Bosch 800 Series 24-inch dishwasher with CrystalDry, PrecisionWash, Home Connect and a 42 dBA noise rating.
Canada
The same model number is listed in Canada, with the Canadian product page describing the machine as an 800 Series 24-inch brushed-steel anti-fingerprint dishwasher. Canadian support documentation is also available for model variants.
United Kingdom
The exact SHX78DM5N should not be treated as a standard UK installation model because its documented electrical specification is 120 V/60 Hz. UK readers can use this review to evaluate the dishwasher’s technology and design, but an appliance specified for the UK electrical and installation environment is the appropriate choice for a normal UK installation.
Bosch SHX78DM5N vs Older Bosch 800 Series Dishwashers
One of the biggest reasons to examine the exact model number is that Bosch has used the 800 Series designation across multiple generations.
The SHX78DM5N has CrystalDry, Home Connect, 42 dBA operation, 16 place settings, 3.2-gallon water use and 240 kWh annual energy consumption.
Older 800 Series dishwashers can have different drying systems, different rack arrangements, different water usage, different energy specifications and different connectivity.
Therefore, an article about one Bosch 800 Series dishwasher should not automatically be applied to every 800 Series model.
The SHX78DM5N is specifically notable because its current-generation feature set includes both CrystalDry and connected functionality.
Bosch SHX78DM5N Pros
CrystalDry
The Zeolite-based drying system is designed to improve drying performance, including on dishwasher-safe plastics.
42 dBA operation
The low rated noise level makes the machine appropriate for open kitchens and frequent nighttime operation.

AquaStop
The 24/7 leak-protection system adds an important safety feature for a water-connected appliance.
ENERGY STAR certification
The model is listed as ENERGY STAR certified with 240 kWh annual energy use and 3.2 gallons per cycle in its specification.
Bosch SHX78DM5N Cons
No built-in water softener
The specification explicitly lists the water softener as absent. This can matter in hard-water regions.
Premium price category
The model sits in Bosch’s 800 Series range rather than its lower-priced dishwasher lines, so buyers are paying for advanced drying, quiet operation, rack flexibility and connected technology.
Smart features require setup
Home Connect adds useful functions, but users who prefer a completely non-connected appliance may not benefit from all of its capabilities.
24-inch installation required
The machine is designed for a standard 24-inch opening and is not intended as a compact or ADA-height replacement.
Hard-water households need additional attention
Because there is no internal water softener, mineral deposits and spotting may require more careful detergent, rinse-aid and maintenance practices in hard-water locations.
Is the Bosch SHX78DM5N Good for Families?
The combination of 16-place-setting capacity, three-rack loading and adjustable rack geometry makes the SHX78DM5N well suited to larger households.
Families can use the third rack for cutlery and utensils while retaining more space below for plates, bowls and cookware.
The Auto cycle can also reduce the need to manually determine the intensity of every load because its operation responds to the detected soil level.
For households that frequently wash plastic lunch containers, bottles and food-storage items, CrystalDry is another particularly relevant feature.
Is It Good for Open-Plan Kitchens?
The 42 dBA rating makes the SHX78DM5N particularly appropriate for open-plan kitchens.
A dishwasher located next to a dining room or living space can be distracting if it produces significant pump and water noise.
The SHX78DM5N’s low sound rating reduces that concern, although the actual perceived sound will depend on installation and the type of operation occurring at a particular moment.
Is It Good for Hard Water?
The answer requires some qualification.
The dishwasher can operate in hard-water homes, but it does not have an integrated water softener.
That means owners in hard-water regions should pay attention to rinse aid, detergent dosage, mineral buildup and regular maintenance.
If your household has exceptionally hard water and you want an appliance with a dedicated built-in water-softening system, the absence of that feature should be considered before purchasing.
Is CrystalDry Worth Paying More For?
For households that frequently struggle with wet plastic containers, CrystalDry can be a particularly meaningful feature.
The technology is designed specifically to absorb moisture with Zeolite and release heat during the drying stage. Bosch states that dishes including plastics can be up to 60% drier compared with its PureDry technology, subject to dish type and loading conditions.
If most of your dishwasher load consists of plates, glasses and metal utensils, the difference may be less important because those materials generally dry more easily.
If your dishwasher regularly contains plastic food containers, bottles and reusable storage items, the feature becomes considerably more relevant.
Is the Bosch SHX78DM5N Energy Efficient?
The SHX78DM5N is ENERGY STAR certified and is specified at 240 kWh/year and 3.2 gallons per cycle.
Those figures correspond to the current ENERGY STAR maximum criteria for standard-size dishwashers, which are 240 kWh/year and 3.2 gallons per cycle.
The machine also incorporates sensor-based washing and Zeolite drying, both of which are intended to manage resource use. The manual describes Normal as its most economical cycle and explains that AquaSensor can reduce water consumption by reusing relatively clean water under appropriate conditions.
Does the SHX78DM5N Need Rinse Aid?
For optimum drying, Bosch recommends using rinse aid.
This remains relevant even though the dishwasher has CrystalDry.
Rinse aid can help reduce water spots and improve the way water leaves dish surfaces during drying.
If you notice wet dishes or spotting, checking the rinse-aid reservoir and dosage setting is one of the simpler troubleshooting steps before assuming that CrystalDry is malfunctioning.
How Long Does the SHX78DM5N Take to Wash?
Cycle duration varies.
The manual lists approximately:
- Heavy: 2 hours 5 minutes to 2 hours 20 minutes
- Auto: 1 hour 45 minutes to 2 hours 5 minutes
- Normal: 2 hours 10 minutes to 2 hours 15 minutes
- Speed60: approximately 1 hour
Actual times can vary according to water temperature, soil level, quantity of dishes and selected options.
This is an important distinction because modern dishwashers often use longer cycles to achieve cleaning and efficiency targets.
A longer cycle does not automatically mean the dishwasher is inefficient. Energy and water consumption need to be evaluated alongside cycle duration.
Does the Dishwasher Have a Sanitize Setting?
Yes. The SHX78DM5N has an NSF-certified sanitize option.
The option increases temperature and cycle duration to provide sanitation and can be appropriate for items such as dishwasher-safe chopping boards and baby bottles.
However, sanitation claims apply to the specific sanitizing cycle and not automatically to every cycle available on the dishwasher.
Does the SHX78DM5N Have a Third Rack?
Yes. It has Bosch’s Flexible 3rd Rack.
The rack provides additional space for utensils and smaller items, and its fold-down sides allow the user to change the available loading area.
This is one of the features that makes the SHX78DM5N easier to organize than a conventional two-rack dishwasher.
Does the SHX78DM5N Have Wi-Fi?
Yes. The model is Wi-Fi enabled and supports Home Connect.
The system supports remote functions, diagnostics, additional cycles and options and software updates.
Does the SHX78DM5N Have CrystalDry?
Yes. CrystalDry is one of the defining features of this model.
The drying system uses Zeolite mineral technology to absorb moisture and release heat during drying.
Does It Have a Water Softener?
No. The official specification identifies the water softener as “No.”
This should be considered carefully by buyers in hard-water areas.
Does It Have AquaStop?
Yes. The model uses 24/7 AquaStop leak protection.
Final Review of the Bosch SHX78DM5N
The Bosch 800 Series SHX78DM5N is a premium dishwasher whose feature set is centered around four major areas: cleaning, drying, quiet operation and convenience.
For cleaning, it combines PrecisionWash, five-level washing, sensor-based AquaSensor operation, Auto cycle adjustment and a Heavy program for difficult soils.
For drying, CrystalDry is the standout technology. Its Zeolite-based system is specifically designed to improve drying performance, including on dishwasher-safe plastics, which are traditionally more difficult to dry than glass, ceramic and metal.
For convenience, the machine provides a Flexible 3rd Rack, RackMatic upper-rack adjustment, Favorite, Home Connect, remote functions and additional app-based cycles and options.
For quiet operation, the 42 dBA specification makes it particularly suitable for open-plan kitchens and households where dishwasher noise is a concern.
Its limitations are also worth remembering. The machine does not have an integrated water softener, requires a conventional 24-inch installation opening, and its exact North American 120 V/60 Hz configuration should not be treated as a normal UK installation appliance.
The energy specification is also interesting because the model is certified at 240 kWh/year and 3.2 gallons per cycle, exactly matching the current ENERGY STAR maximum thresholds for standard-size dishwashers.
Overall, the SHX78DM5N’s most distinctive combination is CrystalDry + 42 dBA + Flexible 3rd Rack + PrecisionWash + Home Connect. Those features make it substantially more technologically advanced than simply choosing a dishwasher because it carries an “800 Series” badge. Its exact specifications should always be checked against other Bosch models because Bosch’s 800 Series lineup contains multiple generations and configurations.

Final Verdict on the Bosch SHX78DM5N
The Bosch SHX78DM5N is a feature-rich 800 Series dishwasher built around quiet operation, advanced drying, flexible loading, sensor-controlled cleaning and connected functionality.
Its CrystalDry system is arguably its most significant differentiator because the Zeolite-based design is specifically intended to improve drying of both conventional dishware and dishwasher-safe plastics.
Its 42 dBA noise rating makes it attractive for open kitchens, while the Flexible 3rd Rack and RackMatic system provide practical loading flexibility rather than simply adding electronic features.
The PrecisionWash and AquaSensor systems also give the machine the ability to adapt washing to load conditions, while Heavy, Auto, Normal and Speed60 cover a useful range of everyday and demanding situations.
The primary limitation is the absence of a built-in water softener. Buyers in hard-water regions should factor that into their decision and consider how they currently manage mineral buildup and spotting.
For USA and Canada buyers seeking a premium full-size dishwasher with strong drying, quiet operation, flexible racks and smart connectivity, the SHX78DM5N has a particularly comprehensive feature set. UK readers should treat the review as a technology and design reference rather than an installation recommendation for the exact North American 120 V/60 Hz model.
