The Bosch 800 Series SGE78C55UC is a 24-inch built-in dishwasher designed to combine premium cleaning, drying, quiet operation, flexible loading, smart connectivity, and accessibility-oriented installation in a relatively low-height cabinet opening. Unlike many standard-height dishwashers, this model is specifically identified as an ADA-compliant dishwasher, making its 32 1/16-inch height one of its most important design characteristics.
The SGE78C55UC belongs to the Bosch 800 Series and uses several technologies associated with the premium tier, including PrecisionWash, CrystalDry, RackMatic, a third rack, Home Connect, and 24/7 AquaStop Plus. It is rated at 42 dBA, provides 15 place settings, uses approximately 3.2 gallons per cycle, and has an annual energy consumption rating of 240 kWh.
There is also an important current-availability issue. The U.S. product page now identifies the SGE78C55UC as no longer available, while the Canadian product page continues to list the exact model at a recommended retail price of C$2,249. This means that anyone researching this model today should distinguish between evaluating an existing appliance and purchasing a new current-generation Bosch dishwasher.
For homeowners who already own the SGE78C55UC, these availability changes do not mean that the dishwasher suddenly becomes obsolete. Bosch continues to provide model-specific support resources, manuals, installation documentation, replacement-part information, and service information for multiple SGE78C55UC production variants.
This detailed review therefore looks at the exact SGE78C55UC rather than treating all 800 Series dishwashers as identical. That distinction matters because Bosch has changed rack systems, wash technology, drying systems, efficiency specifications, handles, dimensions, and connectivity features across different generations and model numbers.

What Is the Bosch SGE78C55UC?
The SGE78C55UC is a 24-inch 800 Series dishwasher with a lower overall height than many conventional built-in dishwashers. Its appliance height is approximately 32 1/16 inches, while the required opening height is approximately 32 1/8 inches. This lower configuration is directly associated with its ADA-compliant design.
The combination of a 24-inch width and lower height makes the model particularly interesting for kitchens where accessibility, countertop height, cabinet configuration, or user reach is an important consideration.
Although its lower height is significant, the dishwasher does not sacrifice the core premium features associated with the 800 Series. It still includes CrystalDry, PrecisionWash, a third rack, RackMatic, Home Connect, AquaStop Plus, stainless-steel construction, and an NSF-certified sanitize option.
The result is a dishwasher aimed at buyers who want a premium full-width machine while also needing a lower installation height.
Design and Exterior
The SGE78C55UC uses a brushed stainless-steel anti-fingerprint exterior. This gives the dishwasher a conventional premium stainless-steel appearance while incorporating a finish intended to reduce visible fingerprints.
The model uses a recessed handle rather than a large protruding bar handle. The recessed design keeps the front relatively clean and streamlined and can work particularly well in kitchens where appliances are expected to have a minimal visual presence.
The control arrangement uses buttons, and the model incorporates a Favorite function. This means users can save a preferred cycle-and-option combination for easier access during regular use.
The exterior design is therefore relatively understated. It does not depend on a large visible control panel or oversized handle to communicate its premium positioning.
Anti-Fingerprint Stainless Steel
The anti-fingerprint stainless finish is useful in kitchens where the dishwasher door is opened frequently. Stainless steel can show fingerprints particularly clearly, especially around the handle area, so a finish designed to reduce those marks can make routine maintenance easier.
However, anti-fingerprint does not mean fingerprint-proof. Oils, cooking residue, water marks, and cleaning-product residue can still appear on the door.
The best results generally come from following the manufacturer’s recommended cleaning method rather than using abrasive materials or aggressive cleaners that could damage the finish.
Dimensions of the SGE78C55UC
The SGE78C55UC measures approximately 32 1/16 inches high, 23 9/16 inches wide, and 22 9/16 inches deep. The specified cutout is approximately 32 1/8 inches high, 24 inches wide, and 24 inches deep.
These dimensions deserve special attention because the dishwasher is intentionally lower than many standard-height models.
A replacement installation should never be based solely on the fact that the existing dishwasher is also 24 inches wide. The height of the opening, countertop relationship, floor conditions, adjustable feet, and surrounding cabinet construction all need to be verified.
Bosch specifically recommends consulting the installation instructions for final dimensional information before making or modifying the cabinet cutout.
ADA-Compliant Design
The SGE78C55UC is identified in its model documentation as an ADA-compliant dishwasher. The manufacturer’s specification sheet specifically describes it as a lower-height dishwasher designed for ease of use.
For an accessibility-focused kitchen, the lower appliance height can make loading and unloading more convenient depending on the user’s reach and the surrounding kitchen layout.
However, ADA compliance of the appliance does not automatically mean that the entire kitchen installation will satisfy every accessibility requirement. Countertop height, cabinet configuration, floor elevation, door clearance, control access, and surrounding maneuvering space also influence accessibility.
For professional accessible-kitchen projects, the dishwasher should therefore be evaluated as part of the complete kitchen rather than as an isolated appliance.
Interior Design and Stainless-Steel Tub
The SGE78C55UC uses a stainless-steel tub, which forms the main interior washing chamber. The model also uses a concealed water-heating element.
The stainless interior provides a durable surface for repeated exposure to hot water, detergent, food residue, and drying temperatures.
The concealed heating element also keeps the main loading area free from a large exposed heating component. Bosch states that its drying and dishwasher designs allow plastics to be loaded without the same concern associated with directly exposed heating elements.
Still, plastic loading should follow the owner’s instructions. Shape, material, location, and exposure to high temperatures can affect individual plastic items.
Capacity: 15 Place Settings
The SGE78C55UC is rated for 15 place settings, making it a full-size dishwasher despite its lower overall height.
A 15-place-setting capacity provides substantially more loading room than compact dishwashers. This makes the model suitable for households that routinely wash dishes from family meals, entertaining, cooking, or larger loads.
The third rack also helps make use of vertical space. Instead of relying entirely on the lower and upper racks, utensils and smaller objects can be placed higher in the dishwasher.
The actual amount of cookware that fits in a load will still depend on the shape of pots, pans, bowls, plates, containers, and serving dishes.
Third Rack
The SGE78C55UC includes a standard third rack. Bosch describes the rack as providing space for silverware and large utensils while its V-shaped configuration leaves room below for taller items.
The third rack is particularly useful for utensils that might otherwise occupy valuable lower-rack space.
Large serving utensils, spatulas, cooking tools, chopsticks, and other narrow objects can often be distributed across the third rack more efficiently than they could be in a traditional silverware basket.
The V-shaped design is also important because it does not simply create another completely flat layer. Its shape is intended to preserve clearance for items below.
RackMatic Three-Step Adjustment
The upper rack uses 3-step RackMatic adjustment, allowing users to alter the rack position to accommodate different dish and cookware heights.
Rack adjustment is particularly valuable when washing mixed loads.
A household might lower or raise the upper rack depending on whether the lower rack contains standard dinner plates, tall cookware, serving bowls, or other unusually large items.
This type of flexibility can be more useful in daily life than simply having a large number of fixed rack tines.
Cleaning Performance and PrecisionWash
The SGE78C55UC uses PrecisionWash, Bosch’s sensor-based dishwasher cleaning system. The manufacturer describes the system as using intelligent sensors to monitor the load and adjust the washing process while precision spray arms target dishes.
The basic advantage of sensor-based washing is that every load is not treated as though it contains the same amount of soil.
A lightly soiled load and a heavily soiled load can require different washing conditions. Sensors can provide information that allows the machine to adjust the cycle rather than simply operating blindly through an identical sequence every time.
Bosch describes PrecisionWash as a system that continually scans and checks the progress of dishes throughout the cycle.
Does PrecisionWash Eliminate Pre-Rinsing?
PrecisionWash is designed to reduce the need for extensive pre-rinsing, but that should not be interpreted as permission to place large quantities of food waste into the dishwasher.
Bosch’s dishwasher guidance has specifically promoted scraping excess food rather than thoroughly rinsing dishes before loading.
This distinction matters because modern dishwashers are designed to process normal food residue, but large pieces of food can still interfere with filters and drainage.
A practical approach is to scrape large leftovers into the trash or compost as appropriate while allowing the dishwasher to handle ordinary residue.
Heavy Soil Performance
The SGE78C55UC has six wash cycles and five options, giving users multiple combinations for different types of loads. It also includes a Machine Care program.
For heavily soiled cookware, cleaning performance depends on the selected cycle, water temperature, detergent, loading arrangement, spray access, and the nature of the food residue.
Even a premium dishwasher cannot clean an item effectively if another dish completely blocks the spray path.
Proper loading remains essential. Plates should be positioned so water can reach their surfaces, bowls should allow drainage, and large cookware should not obstruct spray arms.
PowerControl: An Important Distinction
The exact SGE78C55UC specification sheet lists PrecisionWash, but it does not list the newer PowerControl spray-arm system found on current 800 Series models.
This is an important distinction when researching this dishwasher online.
Current 800 Series marketing emphasizes PowerControl as a newer development that targets heavily soiled dishes on the bottom rack.
Because the SGE78C55UC is an earlier 800 Series generation, articles about current 800 Series models should not automatically be used to claim that this exact dishwasher contains PowerControl.
The SGE78C55UC’s documented cleaning system is PrecisionWash.
CrystalDry: One of the Biggest Features
The SGE78C55UC uses CrystalDry, which is one of its most important premium features.
CrystalDry uses natural minerals to collect moisture and transform it into heat, with Bosch describing the technology as producing heat of up to approximately 176°F that is circulated through the dishwasher.
This technology is particularly notable because plastics are traditionally more difficult to dry than glass, ceramic, or metal.
Plastic tends to retain water droplets because of its surface properties and because many containers have recessed areas where water can collect.
How Well Does CrystalDry Dry Plastics?
Bosch states that CrystalDry delivers 60% better drying results based on an aggregate average of combined household loads containing plastics, glass, steel, and porcelain compared with Bosch dishwashers using PureDry. Bosch also states that actual drying performance can vary by dish type.
That qualification is important.
The 60% figure should not be interpreted as every plastic container becoming exactly 60% drier after every cycle.
It is an aggregate comparison under a defined test basis. Individual results depend on the type of plastic, shape of the container, position in the dishwasher, amount of water retained, and other variables.
Nevertheless, CrystalDry is a meaningful feature for households that frequently wash plastic food containers.
CrystalDry and Everyday Use
For everyday loads containing glasses, plates, stainless-steel utensils, ceramic dishes, and plastic containers, CrystalDry is designed to produce a more thoroughly dried load than conventional drying systems.
This can reduce the amount of manual towel drying required after the cycle.
It can also be useful for households that prefer to put dishes away immediately after the dishwasher finishes rather than leaving them to air-dry.
However, users should still load containers at angles that allow water to drain rather than pool.
Noise Level: 42 dBA
The SGE78C55UC has a rated sound level of 42 dBA.
This is one of the model’s strongest characteristics.
A dishwasher with a 42 dBA rating is designed for quiet operation and can be particularly suitable for open-plan kitchens, kitchens connected to living rooms, and households where the dishwasher is run during conversations, television viewing, or other activities.
Bosch’s current product information continues to describe 42 dBA as a quiet operating level for its dishwasher range.
Is 42 dBA Actually Quiet?
The 42 dBA rating indicates a low published sound level, but it does not mean the dishwasher is literally silent.
The perceived sound can change according to installation, cabinetry, flooring, water pressure, the particular wash phase, pump operation, and the objects inside the dishwasher.
A dishwasher can therefore sound different in a real kitchen than it does in a controlled measurement environment.
Nevertheless, 42 dBA is a strong specification for a full-size dishwasher.
Energy Efficiency
The SGE78C55UC is ENERGY STAR certified and has a listed annual energy consumption of 240 kWh. It uses approximately 3.2 gallons per cycle.
The current ENERGY STAR criteria for standard residential dishwashers specify maximum annual energy consumption of 240 kWh and maximum water consumption of 3.2 gallons per cycle. The SGE78C55UC’s published figures therefore sit exactly at those listed thresholds.
This is important because energy figures can otherwise be misunderstood.
The annual figure is based on standardized testing assumptions rather than the exact number of cycles and settings used by every household.
Actual electricity and water consumption can therefore differ according to usage frequency, cycle selection, incoming water temperature, local utility conditions, and other factors.
Water Consumption
The SGE78C55UC is rated at 3.2 gallons per cycle.
For a full-size dishwasher with a 15-place-setting capacity, this is a significant efficiency characteristic.
Modern dishwasher efficiency depends heavily on using controlled amounts of water while recirculating it through spray systems rather than continuously replacing the water throughout the entire wash.
ENERGY STAR’s current criteria similarly use gallons per cycle as one of the core measures for dishwasher efficiency.
Water Softener
One feature that distinguishes the SGE78C55UC from some Bosch dishwasher models is that the exact specification lists an integrated water softener.
This can be particularly valuable in areas with hard water.
Hard water contains dissolved minerals that can contribute to spots, film, scale, and mineral buildup.
A dishwasher with an integrated softener can condition the incoming water to help manage those minerals, subject to proper setup and the water-hardness requirements in the owner’s instructions.
Why the Water Softener Matters
Hard-water conditions vary significantly between locations.
A household using the dishwasher in an area with relatively soft water may not notice a major difference, while a household in a hard-water region may benefit more from a dishwasher capable of managing water hardness.
The SGE78C55UC also has a dedicated dishwasher salt accessory listed in its specification documentation, which is associated with the water-softening system.
Users should follow the owner’s instructions for water-hardness settings and salt usage rather than adding products randomly.
Sanitize Option
The SGE78C55UC includes an NSF-certified sanitize option according to its model-specific specification sheet.
Residential dishwasher sanitation certification is governed by NSF/ANSI 184. The standard requires a certified dishwasher operating on its sanitizing cycle to achieve at least a 99.999% or 5-log reduction of bacteria under the certification conditions.
This does not mean every cycle provides the same sanitization performance.
The certification applies specifically when the dishwasher is operated using the qualifying sanitizing cycle.
For households concerned with sanitation, baby-related items where dishwasher use is permitted, food-preparation utensils, or other applications where higher-temperature sanitization is desirable, the feature can be valuable.
Home Connect and Wi-Fi
The SGE78C55UC includes Home Connect Wi-Fi connectivity. The model documentation identifies the dishwasher as Wi-Fi enabled and includes Home Connect materials among its support documentation.
Connected functionality can allow users to interact with the appliance through a smartphone and access supported smart features.
The model also supports hands-free voice functionality through compatible voice platforms according to its specification documentation.
Smart features are most useful for households that actively use connected appliances. Someone who prefers simple physical controls may find Wi-Fi less important.
Home Connect Practical Benefits
Connected dishwasher functionality can be useful for monitoring cycles, receiving notifications, accessing appliance information, and integrating the dishwasher into a broader smart-home routine.
However, connected functionality should be viewed as a convenience feature rather than a substitute for dishwasher cleaning performance.
If the dishwasher cleans and dries effectively, the primary benefit of Home Connect is convenience and information rather than fundamental washing capability.
Because connected services can evolve over time, owners of older models should also verify current app compatibility and supported features.
AquaStop Plus Leak Protection
The SGE78C55UC includes 24/7 AquaStop Plus leak protection. Its specification describes a dual-sensor system intended to detect and contain leaks.
Leak protection is particularly important for built-in dishwashers because they remain connected to a water supply even when the dishwasher is not actively running.
An integrated leak-protection system can provide additional protection if a water leak occurs.
However, AquaStop Plus does not eliminate the need for correct installation. Water connections, drainage, electrical connections, and hose routing still need to comply with the installation instructions and applicable local requirements.
Installation Requirements
The required cutout for the SGE78C55UC is approximately 32 1/8 inches high, 24 inches wide, and 24 inches deep. The appliance itself is approximately 32 1/16 × 23 9/16 × 22 9/16 inches.
The dishwasher has adjustable feet, which allow installers to level the appliance within the specified installation range.
The model documentation specifies a 65-inch inlet hose and approximately 74 3/4-inch outlet hose, while the electrical configuration includes a 67-inch power cord.
Because this is an ADA-oriented lower-height model, cabinet preparation deserves particular attention. The countertop, flooring, cabinet opening, and appliance height should be considered together.
Electrical Requirements
The SGE78C55UC is specified for 120 volts, 60 Hz, 12 amps, and 1,440 watts.
This is a North American electrical configuration.
That point is especially important for readers in the United Kingdom. The exact SGE78C55UC should not be treated as a direct UK installation appliance because the UK uses a different domestic voltage and frequency configuration.
The model can therefore be discussed as relevant to U.S. and Canadian dishwasher research, but UK buyers should use a locally specified model designed for the UK’s electrical and installation standards.
SGE78C55UC for the USA
The SGE78C55UC was designed for the North American market and uses a 120 V/60 Hz electrical system. Its full-size 24-inch width, 15-place-setting capacity, and 32 1/16-inch height make it a specialized option for households that want a large-capacity dishwasher with a lower installation profile.
The current U.S. product page, however, lists the model as no longer available.
That means U.S. shoppers should be cautious about listings that appear to show the model as brand new. It is important to verify whether a unit is new old stock, used, refurbished, or simply incorrectly listed.
Warranty status should also be confirmed before purchase.
SGE78C55UC for Canada
The Canadian product listing remains active for the exact SGE78C55UC and currently displays a recommended retail price of C$2,249. The Canadian page identifies the model as an 800 Series 24-inch brushed-steel anti-fingerprint dishwasher and lists CrystalDry, PrecisionWash, 42 dBA, AquaStop Plus, RackMatic, and ADA-oriented features.
The Canadian listing therefore provides a useful reference for readers researching the model in Canada.
Canadian buyers should nevertheless verify current stock, delivery timing, warranty coverage, and installation requirements before ordering because availability can change.
SGE78C55UC for the UK
The SGE78C55UC should not be considered a normal UK-market dishwasher.
Its exact electrical specifications are 120 V and 60 Hz, making it a North American appliance.
For UK readers, the most useful aspects of this review are therefore the dishwasher’s design concepts, CrystalDry technology, cleaning system, rack arrangement, noise level, water softening, accessibility characteristics, and capacity.
A UK installation should use a dishwasher specifically manufactured and certified for the local electrical system.
Reliability and Long-Term Ownership
No specification sheet can guarantee the exact service life of an individual dishwasher.
Long-term reliability depends on factors including installation quality, frequency of use, water quality, detergent, maintenance, component wear, electrical conditions, and service history.
The SGE78C55UC does have model-specific support documentation, including user manuals, installation instructions, Home Connect documentation, product specifications, and replacement-part resources.
That support infrastructure can be important when maintaining an older appliance.
For a discontinued U.S. model, replacement-part availability and authorized service access should be checked before buying a used or remaining-stock unit.
Bosch Service and Parts
Bosch provides owner-support resources for the SGE78C55UC, including access to manuals, replacement parts, service information, and troubleshooting resources.
Bosch also states that its authorized service network includes trained technicians and original parts for major appliance repairs.
For an older dishwasher, the availability of parts can be as important as the initial purchase price.
A cheap used dishwasher that requires a difficult-to-source electronic component may ultimately cost more than a current dishwasher with better parts availability.
Warranty
The published U.S. warranty information for Bosch dishwashers provides one year of limited parts-and-labor coverage for the entire appliance. The published warranty also describes limited parts-only coverage for specified electronics and racks from years two through five, plus certain lifetime rust-through provisions for the inner tub liner and stainless-steel door.
These are general published warranty provisions and should not be treated as a substitute for checking the warranty documentation associated with a particular SGE78C55UC.
This is especially important when purchasing discontinued, used, refurbished, or old-stock appliances.
Maintenance Requirements
The SGE78C55UC should be maintained according to its owner documentation.
Routine maintenance generally involves keeping the filter and interior clean, checking spray arms for obstructions, cleaning the dishwasher as recommended, and monitoring water-hardness-related buildup.
The Machine Care program provides a dedicated method for maintaining the dishwasher interior.
For hard-water households, the water-softening system also requires appropriate setup and maintenance.
Ignoring water hardness can contribute to mineral deposits even in a premium dishwasher.
Is the SGE78C55UC Good for Hard Water?
It can be particularly interesting for hard-water households because the exact model includes an integrated water softener.
This is a meaningful difference compared with models that do not have an internal softening system.
However, the softener must be configured correctly according to the water hardness of the installation location.
Users should also use dishwasher salt where required by the model’s instructions rather than assuming detergent alone performs the same function.
Is the SGE78C55UC Good for Plastics?
The SGE78C55UC is particularly well suited to households that wash plastics because it uses CrystalDry.
Bosch’s published CrystalDry information states that the technology produces 60% better drying results on aggregate combined household loads containing plastics, glass, steel, and porcelain compared with PureDry-equipped Bosch dishwashers, while also noting that actual results vary by dish type.
This makes CrystalDry one of the most meaningful reasons to consider the model over older drying systems.
Plastic containers should still be loaded so water can drain rather than pool.
Is the SGE78C55UC Good for Families?
The 15-place-setting capacity makes the SGE78C55UC suitable for many family households.
Its three-rack arrangement also helps divide dishes, utensils, glasses, and larger cookware across the available vertical space.
For households that cook frequently, the flexible rack arrangement can be especially useful because the dishwasher does not need to be loaded identically every day.
Large families should nevertheless compare the capacity with their actual dish volume. A 15-place-setting rating does not guarantee that a large collection of oversized cookware will fit in one cycle.
Is the SGE78C55UC Good for Open-Plan Kitchens?
The 42 dBA noise rating makes the dishwasher particularly relevant to open-plan kitchens.
A dishwasher located next to a living room, dining area, or kitchen island can become irritating if it generates significant mechanical noise.
The low sound rating reduces that concern.
The dishwasher will still produce some sound during filling, pumping, draining, and spray operation, but 42 dBA is a quiet published rating.
Advantages of the Bosch SGE78C55UC
1. 42 dBA quiet operation
The 42 dBA rating makes this model a strong choice for kitchens where appliance noise is important.
2. CrystalDry
CrystalDry is designed to improve drying performance, including on plastics, and is one of the model’s major premium features.
3. 15-place-setting capacity
The dishwasher provides the capacity expected from a full-size 24-inch machine.
4. Third rack
The third rack provides additional space for utensils and smaller items while preserving room on the lower racks.
5. RackMatic
Three-step upper-rack adjustment provides flexibility for tall cookware and different loading configurations.
6. Water softener
The integrated water softener is particularly useful for households in hard-water regions.
7. NSF-certified sanitize option
The model includes an NSF-certified sanitize option, providing a documented sanitation capability when the qualifying cycle is used.
8. AquaStop Plus
The dual-sensor leak-protection system provides an additional layer of protection for a water-connected appliance.
9. Home Connect
Wi-Fi connectivity provides additional convenience for households interested in smart-appliance functionality.
10. ADA-compliant lower height
The lower-height configuration can be important for accessible kitchen designs.
Disadvantages of the Bosch SGE78C55UC
1. U.S. availability
The U.S. product page now identifies the model as no longer available.
2. Older model generation
Newer Bosch 800 Series models have introduced additional technologies and different configurations, so the SGE78C55UC should not automatically be treated as equivalent to the latest 800 Series products.
3. Lower height can complicate replacement
The 32 1/16-inch height is useful for ADA-oriented applications but may not directly match every existing dishwasher opening.
4. Premium purchase price
The Canadian manufacturer’s recommended retail price is listed at C$2,249, placing the dishwasher firmly in the premium category.
5. Exact model availability varies by market
The U.S. and Canadian listings currently have different availability statuses, so buyers should verify local stock rather than relying on generic online listings.
Bosch SGE78C55UC vs Newer 800 Series Dishwashers
One of the most important lessons when researching Bosch dishwashers is that series names do not tell the entire story.
The SGE78C55UC has CrystalDry, PrecisionWash, 42 dBA operation, a third rack, RackMatic, Home Connect, and AquaStop Plus.
However, newer 800 Series models can include PowerControl, which Bosch currently describes as an enhanced spray-arm technology designed to target heavily soiled dishes on the bottom rack.
The SGE78C55UC specification does not list PowerControl, so it should not be marketed as though it includes that newer feature.
This distinction is particularly important for SEO product reviews because many current Bosch 800 Series pages describe technologies that were introduced or changed after the SGE78C55UC generation.
Should You Buy the SGE78C55UC?
For someone who specifically needs a lower-height 24-inch dishwasher, the SGE78C55UC remains a feature-rich option.
The combination of ADA-oriented dimensions, 15-place-setting capacity, 42 dBA operation, CrystalDry, PrecisionWash, third-rack loading, RackMatic, water softening, Home Connect, AquaStop Plus, and NSF-certified sanitization gives the model a comprehensive premium feature set.
For a buyer who does not need the lower-height configuration, however, newer models may deserve consideration because the SGE78C55UC is no longer listed as available in the United States.
The buying decision should therefore depend on availability, price, installation requirements, and whether the exact features of this model match the household’s needs.
Final Bosch SGE78C55UC Review
The Bosch 800 Series SGE78C55UC is a premium 24-inch dishwasher with a particularly useful combination of features.
Its 42 dBA noise rating makes it suitable for open kitchens. Its 15-place-setting capacity gives it the loading space expected from a full-size dishwasher. Its third rack and RackMatic system provide flexibility for mixed loads. Its PrecisionWash system provides sensor-based cleaning, while CrystalDry addresses one of the most common dishwasher complaints: wet dishes, particularly plastics.
The integrated water softener is another significant advantage for hard-water households. The NSF-certified sanitize option adds a documented sanitation capability when the appropriate cycle is used, while AquaStop Plus provides additional leak protection.
Energy and water performance are also strong on paper. The model is ENERGY STAR certified and is rated at 240 kWh annually and 3.2 gallons per cycle, matching the current ENERGY STAR maximum thresholds for standard dishwashers.
The biggest consideration today is availability. The U.S. product page identifies the SGE78C55UC as no longer available, while the Canadian product page continues to list it.
For an existing owner, the dishwasher remains a sophisticated machine with model-specific support resources and replacement-part documentation.
For a buyer looking at old stock or a used unit, the most important questions are whether the dishwasher fits the intended opening, whether the lower ADA-oriented height is desirable, whether the warranty is valid, and whether service and replacement parts are accessible in the buyer’s region.
Overall, the SGE78C55UC is best understood not simply as another Bosch 800 Series dishwasher but as a lower-height, ADA-compliant, full-size 24-inch 800 Series model with CrystalDry, PrecisionWash, water softening, smart connectivity, quiet 42 dBA operation, and a 15-place-setting capacity.

Is the SGE78C55UC worth buying today?
It can make sense when its lower ADA-oriented height, CrystalDry system, water softener, 42 dBA operation, 15-place capacity, and other features specifically match the buyer’s requirements. However, U.S. availability is now limited because the official U.S. product page identifies it as no longer available.
What is the biggest advantage of the SGE78C55UC?
The combination of a lower-height 24-inch design and premium 800 Series features is its defining advantage. It provides full-size capacity while accommodating a lower installation configuration.
What is the biggest disadvantage?
Current availability is the biggest concern for new buyers, particularly in the United States. The model is also an earlier 800 Series generation, so newer models may have technologies that are not present on the SGE78C55UC.
Final Verdict on the Bosch SGE78C55UC
The Bosch 800 Series SGE78C55UC is a feature-rich full-size dishwasher that stands out because of its ADA-compliant lower height rather than because of a radically different washing system.
Its combination of PrecisionWash, CrystalDry, 42 dBA operation, 15 place settings, a third rack, RackMatic, water softening, Home Connect, AquaStop Plus, and NSF-certified sanitation makes it a comprehensive premium dishwasher platform.
For households with hard water, the integrated water softener is especially useful. For households that struggle with wet plastics, CrystalDry is one of the model’s most significant advantages. For open-plan kitchens, 42 dBA operation is a strong characteristic. For accessibility-oriented kitchen projects, the lower height is arguably the feature that makes the model most distinctive.
Its energy and water specifications are also solid: 240 kWh annually and 3.2 gallons per cycle, with ENERGY STAR certification.
The major caveat is availability. The U.S. product page currently says the SGE78C55UC is no longer available, while the Canadian product page continues to list the model.
Therefore, this model makes the most sense when someone specifically needs its lower-height configuration or is evaluating an existing appliance. Buyers looking for a brand-new dishwasher should compare the exact SGE78C55UC specifications with currently available 800 Series models rather than assuming that the newest models are identical.
For existing owners, however, the SGE78C55UC remains a sophisticated dishwasher with a strong combination of quiet operation, cleaning technology, drying performance, flexible loading, smart connectivity, water softening, and leak protection.
