The Bosch 800 Series SGX78C55UC is a premium 24-inch built-in dishwasher designed around a combination of quiet operation, strong cleaning performance, improved drying, flexible loading and smart-home connectivity. Unlike many standard-height 800 Series dishwashers, this model is specifically designed as an ADA-compliant lower-height dishwasher, making its installation dimensions particularly important for anyone replacing an existing dishwasher in an accessible kitchen or a kitchen with a lower countertop configuration. It combines a stainless-steel interior, PrecisionWash cleaning, CrystalDry drying, a third rack, RackMatic adjustability, Home Connect connectivity and 24/7 AquaStop Plus leak protection.
At 42 dBA, the SGX78C55UC is built for quiet operation, while its CrystalDry system is intended to address one of the common weaknesses of many modern dishwashers: incomplete drying, particularly on plastics. The machine uses 3.2 gallons of water per cycle and has a stated annual energy consumption of 240 kWh, while also carrying ENERGY STAR certification according to its technical documentation. Its 15-place-setting capacity and three-rack configuration are aimed at households that want to load more small utensils, flatware and awkward items without sacrificing useful space on the lower racks.

What Is the Bosch SGX78C55UC?
The SGX78C55UC belongs to the Bosch 800 Series and is a 24-inch ADA-compliant dishwasher with a stainless-steel exterior and bar-handle configuration. The lower overall height is one of its most important distinguishing characteristics because it changes the installation requirements compared with a conventional-height built-in dishwasher. The documented appliance height is 32 1/16 inches, while the required cutout height is 32 1/8 inches.
The ADA-compliant design can be particularly useful in kitchens where a conventional 33 7/8-inch dishwasher would not fit beneath the countertop. However, buyers should not assume that the lower height automatically makes it a better choice for every kitchen. The cabinet opening, countertop height, flooring, plumbing position and electrical arrangement all need to be checked before installation. Bosch specifies a 32 1/8-inch minimum cutout height and a 24-inch cutout width and depth, so measuring the existing opening is essential.
Design and Exterior
The SGX78C55UC uses a stainless-steel exterior with a bar handle rather than a fully integrated custom-panel configuration. This gives it the familiar appearance of a conventional stainless-steel dishwasher while retaining the lower-height ADA construction. The technical documentation also identifies an anti-fingerprint finish on the stainless-steel model in current product documentation.
The controls are positioned at the top edge of the dishwasher door, helping maintain a clean front appearance when the dishwasher is closed. Bosch’s documentation identifies buttons as the control type and includes an InfoLight feature that provides a visual indication during operation.
The lower-height body also changes how the dishwasher sits relative to the surrounding cabinets. This is particularly important when replacing a standard dishwasher because an ADA-height model can leave a different relationship between the dishwasher door, countertop and flooring. Installation should therefore be treated as a dimensional project rather than simply a matter of sliding the new appliance into an existing opening.
42 dBA Noise Level
One of the strongest characteristics of the SGX78C55UC is its 42 dBA rated sound level. Bosch positions this level as quiet enough that normal kitchen conversations can continue without the dishwasher becoming a dominant source of background noise. The manufacturer’s current product documentation consistently lists the model at 42 dBA.
A 42 dBA rating is particularly relevant in open-plan homes. If the kitchen opens directly into a family room, dining room or living area, dishwasher noise can become noticeable during evening meals, television viewing or conversations. A lower sound rating reduces that intrusion, although actual perceived noise can still vary according to installation, cabinet construction, flooring, plumbing and the type of sounds generated by individual wash loads.
It is also important not to interpret 42 dBA as complete silence. A dishwasher still produces sounds from pumps, water circulation, draining and dish movement. The advantage is that these sounds are designed to remain relatively subdued rather than dominating the room. Bosch’s 42 dBA specification therefore represents an important part of the SGX78C55UC’s premium positioning.

Cleaning Performance
The SGX78C55UC uses PrecisionWash, Bosch’s sensor-driven washing system. Instead of relying solely on a fixed wash pattern, the system is designed to monitor conditions and adjust washing activity to the load. This approach is intended to deliver effective cleaning while avoiding unnecessary use of water and energy.
The dishwasher also uses a five-level wash system, which helps distribute water through multiple levels inside the tub. The combination of multiple spray levels, sensors and targeted water delivery is designed to reach dishes throughout the three-rack configuration.
For everyday loads containing plates, bowls, glasses, cutlery and cooking utensils, the system is designed to reduce the need for intensive manual pre-cleaning. However, dishwasher performance still depends on loading technique, detergent selection, water temperature, soil level and maintenance. Even a premium dishwasher cannot compensate completely for blocked spray arms, overloaded racks or dishes positioned so that water cannot reach their surfaces.
Heavy and Dried-On Food
The Heavy programme is intended for more demanding loads, including cookware and heavily soiled dishes. PrecisionWash and the dishwasher’s heating system work together to provide the conditions required for difficult food residues.
For baked-on food, dried starches, egg residue or heavily caramelized sauces, it is still sensible to remove large food particles before loading. Scraping is different from extensive hand-washing: the goal is to prevent large debris from interfering with the dishwasher rather than completely cleaning the dishes before they enter the machine. Proper loading also matters because water needs a clear path to the surfaces being cleaned.
CrystalDry: The Major 800 Series Feature
One of the defining technologies in the SGX78C55UC is CrystalDry. Bosch describes the system as transforming moisture into heat to improve drying performance, including on plastics. The manufacturer’s specification sheet states that its comparison claim is based on aggregate testing and should not be interpreted as every individual dish becoming exactly the same percentage drier.
This is important because plastic containers and lids are among the most difficult dishwasher items to dry. Plastic has relatively low thermal mass and does not retain heat in the same way as ceramic or metal. As a result, condensation can remain on plastic surfaces even after the dishwasher has completed its cycle.
CrystalDry is designed to address that problem by using a mineral-based drying process to convert moisture into heat. The objective is not merely to leave dishes warm but to improve the overall removal of residual moisture from the load.
For households that frequently wash reusable plastic containers, children’s items, food-storage lids or plastic cooking accessories, this feature can be especially relevant. It does not mean every plastic object will emerge completely dry under every load condition, but it is specifically intended to improve the situation compared with simpler drying systems.
Third Rack
The SGX78C55UC includes a standard third rack, giving users another dedicated loading level for flatware, utensils and smaller objects. Bosch’s documentation describes the third rack as having a V-shaped design that creates additional room underneath for taller items.
A third rack changes how the dishwasher can be loaded. Instead of putting every utensil into a traditional silverware basket, long-handled utensils, spatulas and certain cooking tools can be placed higher in the tub. This can free space in the lower rack and make loading more organized.

The third rack is particularly useful for households that regularly wash large quantities of cutlery or kitchen utensils. However, its usefulness depends on the user’s loading habits. People who prefer a traditional basket may need some time to adapt to the additional rack.
RackMatic Adjustable Upper Rack
The SGX78C55UC uses RackMatic, allowing the upper rack to be raised or lowered. Bosch’s technical information identifies three-step rack adjustment.
This flexibility is important because dishware is rarely uniform. A household might wash tall wine glasses in one load and large pots or bowls in another. Being able to reposition the upper rack provides more control over the vertical space available in the lower rack.
The adjustment system is also useful when the third rack is loaded with taller utensils because users can configure the middle rack around the objects being washed below and above it. This makes the interior more adaptable than a fixed two-rack layout.
15-Place-Setting Capacity
The SGX78C55UC is specified for 15 place settings. That provides substantial capacity for a lower-height dishwasher, although the way that capacity is experienced depends heavily on how the three racks are loaded.
The three-level arrangement allows smaller objects to be moved upward while leaving the lower rack available for larger plates, cookware and serving pieces. This can be particularly beneficial for families or households that prefer running a dishwasher once per day rather than several smaller loads.
Capacity should not be judged solely by the advertised number of place settings. Large cookware can consume substantial rack space, while a third rack can significantly improve usable capacity for smaller objects. The SGX78C55UC’s design is therefore more about flexible capacity than simply fitting a large number of identical plates.
Stainless-Steel Interior
The dishwasher uses a stainless-steel tub. Stainless interiors are common in premium dishwashers because they provide a durable interior surface and work well with high-temperature washing and drying environments.
The stainless interior also complements the machine’s premium construction. A dishwasher interior experiences repeated exposure to water, detergent, heat and food residue, so material durability matters over years of operation.
Water Softener
A particularly notable specification is the inclusion of a water softener. The technical documentation specifically lists the SGX78C55UC as having one.
This can be valuable in areas with hard water. Hard water contains minerals such as calcium and magnesium that can contribute to spotting, mineral deposits and scale inside appliances. A dishwasher water-softening system can help manage those minerals and improve washing conditions.
The practical benefit depends on the local water supply. In areas with relatively soft water, the feature may be less important. In hard-water regions, however, correct salt usage and adjustment of the water-softener setting can be important for maintaining performance.
Users should follow the model-specific instructions for dishwasher salt and water-softener adjustment rather than assuming the machine should be configured identically in every location. Water hardness varies considerably between municipalities and regions.

Sanitize Option
The SGX78C55UC includes an NSF-certified sanitize option according to its technical documentation.
Residential dishwasher sanitation certification is associated with NSF/ANSI 184. The standard requires a certified residential dishwasher’s sanitizing cycle to achieve at least a 99.999% or 5-log reduction of bacteria and reach a final rinse temperature of 150°F under the certification conditions. Importantly, the sanitation performance applies when the designated sanitizing cycle is used.
This makes the sanitize option useful for situations where higher-temperature sanitation is desirable, such as cleaning heavily used cookware, food-preparation items or certain household items suitable for dishwasher sanitation.
It should not, however, be interpreted as meaning that every dishwasher cycle provides the same sanitization performance. The certification relates specifically to the qualifying sanitizing operation and its tested conditions.
Energy Efficiency
The SGX78C55UC is listed as ENERGY STAR certified, with manufacturer documentation specifying 240 kWh of annual energy consumption and 3.2 gallons of water per cycle.
The current ENERGY STAR criteria for standard residential dishwashers require annual energy consumption of no more than 240 kWh and water consumption of no more than 3.2 gallons per cycle. These figures are determined using standardized testing procedures, so they provide a consistent basis for comparing qualifying products.
The 240-kWh annual figure should not be interpreted as a guarantee of an individual household’s electricity consumption. Actual energy use can vary according to cycle selection, frequency of use, options such as sanitation and drying, water temperature and local operating conditions.
The same applies to the 3.2-gallon water figure. It is a standardized rated consumption figure rather than a promise that every possible programme and load will use exactly 3.2 gallons.
Water Consumption and Hard-Water Performance
Using up to 3.2 gallons per cycle under its rated conditions places the SGX78C55UC within the current ENERGY STAR standard for standard residential dishwashers.
For households in hard-water areas, the integrated water softener becomes particularly relevant. Mineral buildup can affect spray components, heating surfaces, interior surfaces and dish appearance over time. Correct dishwasher salt use and appropriate water-hardness settings can therefore be important parts of long-term maintenance.
The combination of efficient water use and water softening makes this model potentially interesting for homes where water quality is a concern. Nevertheless, the exact maintenance requirements vary according to local water hardness.
Home Connect Smart Features
The SGX78C55UC supports Home Connect, giving users connected control and monitoring functions through compatible devices. The technical documentation identifies Wi-Fi connectivity, while Bosch’s documentation also describes connected features such as remote monitoring and control.
Smart connectivity can be useful for households that want to monitor dishwasher status without physically opening the appliance. Depending on the supported software and region, connected features can include notifications, remote operation and additional control functions.
The smart functions should be considered an additional convenience rather than the fundamental reason to purchase the machine. Cleaning, drying, capacity, installation compatibility and reliability remain more important considerations for most households.
Favorite Programme
The SGX78C55UC includes a Favorite function. This allows frequently used combinations or settings to be more readily accessible, depending on how the appliance and connected controls are configured. Bosch lists Favorite among the model’s special features.
This can be convenient for households that repeatedly use the same cycle and options. Instead of navigating through multiple settings every time, the frequently used configuration can be easier to access.

Wash Cycles
The technical documentation lists six control-panel wash cycles: Heavy, Auto, Normal, Favorite, Express and Delicate. MachineCare is identified as a special maintenance programme.
The variety gives the dishwasher flexibility for everyday loads, heavily soiled cookware, faster loads and more delicate items. Auto cycles can be particularly useful when the amount and type of soil varies from load to load because sensor-based washing can adapt operation.
Express is designed for situations where users need a shorter programme, while Delicate provides a programme option for suitable fragile items. Users should always check the care instructions of individual dishes and glassware before selecting a programme.
MachineCare
MachineCare is intended to help maintain the dishwasher itself rather than simply wash dishes. Regular appliance maintenance is important because food debris, grease, mineral deposits and detergent residue can accumulate in areas that are not cleaned simply by running ordinary loads.
The presence of a dedicated MachineCare programme is useful because it gives the owner a structured maintenance option. However, it does not eliminate the need for basic maintenance such as checking filters, cleaning accessible areas and inspecting spray arms.
AquaStop Plus Leak Protection
The SGX78C55UC uses 24/7 AquaStop Plus, which Bosch describes as a leak-protection system using dual-sensor technology to detect and contain leaks.
Water protection is particularly important for built-in dishwashers because a slow leak can potentially affect cabinetry, flooring and adjacent materials. A system designed to detect and contain water provides an additional layer of protection beyond simply relying on the plumbing connection.
Leak protection does not mean the appliance can never leak. Installation quality, hoses, connections, seals and household plumbing remain important. The feature should therefore be viewed as risk reduction rather than a guarantee against every possible water-related problem.
InfoLight
The dishwasher includes InfoLight, which provides a visual indication when the appliance is operating. This can be useful because the controls are positioned on the top edge of the door and may not be visible when the dishwasher is closed.
A simple operating indicator becomes more useful on a quiet dishwasher. When a machine operates at 42 dBA, users may not always notice that it is running, so an external visual indicator can help prevent accidentally opening the dishwasher during an active cycle.
ADA-Compliant Design
One of the most important reasons someone might choose the SGX78C55UC over a conventional 800 Series model is its ADA-compliant lower height. Bosch lists an overall appliance height of 32 1/16 inches and a required cutout height of 32 1/8 inches.
The ADA configuration can make the dishwasher more accessible in kitchens designed around lower installation heights. It may also solve an installation problem when a standard-height dishwasher is physically too tall.
However, buyers should not choose the model simply because the word ADA appears in its specifications. The lower height means it is not a direct dimensional replacement for every conventional dishwasher. Cabinet measurements should be confirmed before ordering.

Installation Requirements
The required cutout is approximately 32 1/8 inches high, 24 inches wide and 24 inches deep. The appliance itself is 32 1/16 × 23 9/16 × 22 9/16 inches.
The documentation specifies a minimum water pressure of 7 psi and identifies a 67-inch power cord for the supplied electrical arrangement. It also specifies plumbing requirements for the included drain hose and its installation height.
Bosch’s installation documentation indicates that the drain hose should have a raised portion between 33 and 43 inches above the cabinet floor, helping prevent improper drainage conditions. Actual installation must also comply with applicable local plumbing and electrical codes.
For replacement projects, homeowners should therefore measure the cabinet opening, check the floor height, verify water and electrical access and confirm that the door can open properly without interference from adjacent cabinets.
Is the SGX78C55UC Good for the USA?
For the United States, the SGX78C55UC is a clearly documented 800 Series ADA-compliant model. Its 42 dBA noise rating, CrystalDry drying, PrecisionWash, 15-place-setting capacity, water softener, Home Connect and AquaStop Plus make it a feature-rich dishwasher for households that specifically need a lower-height installation.
Its U.S. electrical specification is 120 V, 60 Hz and 12 amps, with a 1,440-watt rating. Those figures are important because electrical requirements should always be checked against the installation instructions and local code rather than assumed from another country’s version of the product.
Is the SGX78C55UC Good for Canada?
The SGX78C55UC is also listed through the Canadian product channel, where it retains the 800 Series designation and core features such as CrystalDry, PrecisionWash, 42 dBA operation, the third rack and Home Connect.
Canadian buyers should still confirm the exact model suffix, installation requirements, included accessories, warranty terms and electrical configuration for the unit supplied in their province. Product availability, pricing and service arrangements can change independently of the underlying dishwasher design.
Is the SGX78C55UC Suitable for the UK?
The SGX78C55UC model number is present in UK support documentation, including documentation for Home Connect and appliance specifications. However, the model’s detailed North American specification sheet is the clearest source for the 42 dBA, 120 V/60 Hz, 3.2-gallon, 15-place-setting ADA configuration discussed in this review.
This distinction matters because dishwasher model numbers can have different regional specifications, programmes, electrical requirements and regulatory configurations. A UK buyer should therefore verify that the exact SGX78C55UC version being offered is intended for UK installation rather than assuming that the North American specification applies unchanged.
Reliability and Long-Term Ownership
The SGX78C55UC contains a number of systems that can improve everyday convenience, but more features also mean more components. PrecisionWash, CrystalDry, Home Connect, AquaStop Plus, the water softener, third rack and electronic controls all add functionality compared with a basic dishwasher.
Long-term reliability is therefore influenced not only by the underlying mechanical design but also by installation, water quality, detergent use, cleaning habits and maintenance. Keeping filters clean, maintaining spray arms, using the appropriate detergent and rinse aid, and addressing unusual noises or leaks early can help reduce avoidable problems.
A premium dishwasher should not be treated as maintenance-free. Regular maintenance is still important even when the appliance has automatic cleaning and monitoring systems.

Bosch Warranty
For U.S. dishwashers, the manufacturer’s published warranty information lists one year of limited coverage for the entire appliance including parts and labor. It also identifies additional limited coverage for electronics and racks during years two through five, plus lifetime limited parts coverage for certain rust-through conditions involving the inner tub liner and stainless-steel door. Exact terms are governed by the applicable warranty documentation.
This distinction is important because a longer warranty period for a particular component does not necessarily mean that labor is covered for the same period. Buyers should read the warranty terms applicable to the exact model and country of purchase.
Canadian and UK warranty arrangements can differ from U.S. terms, so buyers outside the United States should verify the warranty provided with their locally supplied appliance.
Maintenance Tips
Owners should periodically inspect and clean the dishwasher filter according to the manufacturer’s instructions. Food debris accumulating in the filtration system can affect drainage, odors and cleaning performance.
Spray arms should also be checked for blocked openings. Small food particles and mineral deposits can interfere with water distribution. If a spray arm does not rotate properly or has blocked openings, cleaning performance can deteriorate.
Hard-water households should pay particular attention to mineral buildup and the dishwasher’s water-softener settings. The presence of a water softener is useful, but it still needs to be configured and maintained correctly.
Door seals should be kept clean, and owners should inspect the area around the door for food residue or buildup. Cleaning the seal helps maintain a proper door closure and reduces the accumulation of debris.
Cycle Time Considerations
One trade-off with sophisticated modern dishwashers is that some programmes can take considerably longer than older machines. Longer cycles are often associated with lower resource consumption and sensor-controlled operation, especially when the machine needs to heat water and provide extended cleaning or drying.
The SGX78C55UC provides an Express cycle for situations where speed is more important. However, users should not expect the fastest programme to provide identical cleaning and drying performance to the longest intensive programmes.
For everyday loads, selecting the cycle according to soil level is usually more sensible than automatically choosing the longest or shortest programme.
SGX78C55UC vs Standard-Height Bosch 800 Series Dishwashers
The biggest difference is not necessarily cleaning technology but installation height. The SGX78C55UC is an ADA-compliant lower-height dishwasher, while many conventional 800 Series models use a taller standard installation dimension.
This makes the SGX78C55UC particularly relevant for accessible kitchens or installations where the available height is limited. Conversely, someone with a standard 33 7/8-inch dishwasher opening should not assume that the lower model is a direct substitute without considering the resulting cabinet gap and installation configuration.

SGX78C55UC vs Bosch 500 Series
The 800 Series positioning is reflected in the combination of features offered by the SGX78C55UC. CrystalDry is a major differentiating technology, while the third rack, water softener, Home Connect, AquaStop Plus and premium control features contribute to its higher-level configuration.
A 500 Series dishwasher may be sufficient for someone primarily concerned with reliable cleaning and quiet operation, but the 800 Series model is aimed at users who place greater importance on drying technology, loading flexibility and additional convenience features.

Who Should Consider the SGX78C55UC?
The SGX78C55UC makes particular sense for someone who needs an ADA-compliant lower-height dishwasher but does not want to sacrifice premium dishwasher features. The combination of CrystalDry, PrecisionWash, a third rack, RackMatic, water softening, quiet operation and connected controls makes it considerably more sophisticated than a basic lower-height dishwasher.
It can also make sense for households where drying performance matters. People who frequently wash plastic containers, reusable food-storage products and mixed loads may find the CrystalDry system particularly relevant.
Hard-water households are another potential match because the built-in water softener can help manage mineral-related washing issues when correctly configured and maintained.
Who May Not Need It?
Someone with a standard-height installation and no accessibility requirement may have more dishwasher configurations available. If the lower ADA height is unnecessary, standard-height models can be easier to compare and install because their dimensions are more common.
Likewise, someone who primarily wants the lowest possible purchase cost may not benefit from paying for premium drying, connectivity and water-softening technology.
The SGX78C55UC is best viewed as a feature-rich lower-height 800 Series dishwasher rather than simply a generic 24-inch dishwasher.
Final Bosch SGX78C55UC Review
The Bosch 800 Series SGX78C55UC is a premium ADA-compliant dishwasher built around four major priorities: quiet operation, advanced cleaning, improved drying and flexible loading. Its 42 dBA sound rating, PrecisionWash system, CrystalDry drying technology, third rack, RackMatic upper rack, water softener, Home Connect connectivity and AquaStop Plus protection give it a comprehensive feature set.
Its lower height is arguably just as important as its 800 Series technology. At 32 1/16 inches high, it is designed for a different installation requirement from a standard-height dishwasher. That makes careful measurement essential before purchase.
Cleaning performance is supported by PrecisionWash and the five-level wash system, while CrystalDry addresses the persistent problem of moisture left on dishes, especially plastics. The third rack and adjustable middle rack also give users more flexibility when loading mixed household items.
Efficiency is another important strength on paper. The machine is rated at 3.2 gallons per cycle and 240 kWh annually, matching the current maximum consumption thresholds used for ENERGY STAR qualification of standard dishwashers.
The sanitation option adds another useful capability, with the model’s documentation identifying an NSF-certified sanitize option. NSF/ANSI 184 defines the performance requirements for certified residential dishwasher sanitation, including the required bacterial reduction and final-rinse conditions.
Overall, the SGX78C55UC is particularly suited to buyers who need ADA-compliant dimensions without giving up premium dishwasher features. Its combination of quiet operation, advanced drying, water softening, flexible racks, leak protection and smart connectivity makes it a technically comprehensive 800 Series model.
The most important question for a potential buyer is therefore not simply whether the dishwasher has enough features. It is whether the ADA height, 24-inch width, installation requirements and premium feature set match the kitchen and household’s actual needs. For the right installation, the SGX78C55UC offers a strong combination of convenience, cleaning technology, drying capability and accessibility.

49. Is the SGX78C55UC a good choice for a family?
Its 15-place-setting capacity, third rack, adjustable middle rack and flexible wash programmes make it suitable for households that regularly wash substantial mixed loads.
50. Is the Bosch SGX78C55UC worth considering?
For buyers who need its lower ADA-compliant height and want premium features such as CrystalDry, PrecisionWash, a third rack, water softening, Home Connect and AquaStop Plus, the SGX78C55UC provides a comprehensive feature package. The key consideration is whether those features and the specific installation dimensions match the household’s requirements.
Bottom Line
The Bosch SGX78C55UC is not simply a smaller version of a conventional dishwasher. It is a purpose-built ADA-compliant 800 Series model that combines a lower installation height with premium cleaning, drying, loading, connectivity and leak-protection technologies. Its 42 dBA operation, CrystalDry system, PrecisionWash, third rack, RackMatic adjustment, water softener and Home Connect make it a technically sophisticated option.
For U.S. and Canadian buyers, the documented specifications provide a clear picture of what the model offers. For UK buyers, the model number appears in regional support documentation, but the exact local specification should be confirmed because electrical and programme configurations can vary between markets.
The most important buying consideration remains installation compatibility. If the kitchen requires a lower ADA-compliant dishwasher, the SGX78C55UC’s combination of accessibility and 800 Series technology makes it a particularly feature-rich configuration. If ADA height is not required, buyers should compare it against standard-height models because the lower dimensions can change installation compatibility.
