The Bosch 800 Series SPX68U55UC is an unusual dishwasher because it combines the feature set of Bosch’s premium 800 Series with a compact 18-inch-wide, ADA-oriented design. Unlike the standard 24-inch Bosch dishwashers that dominate the market, the SPX68U55UC is designed for kitchens where cabinet space is limited but the homeowner still wants a stainless-steel interior, third rack, water softener, quiet operation, adjustable rack system and sophisticated cleaning technology. Bosch’s exact model specification lists a 44 dBA noise level, six wash cycles, five options, 10-place-setting capacity, a stainless-steel tub and 3.0 gallons of water consumption per cycle.
The model is also important to research carefully because it belongs to an older generation of the Bosch 800 Series. Bosch’s current 800 Series lineup emphasizes newer technologies such as CrystalDry and PowerControl, but those technologies should not automatically be attributed to the SPX68U55UC. The exact SPX68U55UC specification instead identifies PrecisionWash, a standard third rack, RackMatic, a water softener, Eco Cycle, InfoLight and 24/7 AquaStop Plus.
For someone searching for a narrow dishwasher for a smaller kitchen, apartment, condo, accessible kitchen or secondary kitchen, the SPX68U55UC can therefore be a particularly interesting model. Its 17 5/8-inch actual width is substantially narrower than a conventional 24-inch dishwasher, while its 10-place-setting capacity makes use of the available interior space efficiently.
This review examines the SPX68U55UC in detail, including its dimensions, design, loading system, cleaning performance, drying system, noise level, water consumption, energy efficiency, hard-water performance, sanitation, installation requirements, maintenance, warranty considerations and suitability for the USA, Canada and UK.

What Is the Bosch SPX68U55UC?
The SPX68U55UC is an 18-inch Bosch 800 Series dishwasher with a stainless-steel exterior and bar handle. Its narrower configuration is the defining characteristic of the appliance. Bosch classified this family of 18-inch models as a special-application configuration, alongside other 18-inch 800 Series models with different exterior designs.
The dishwasher measures approximately 32 1/16 inches high, 17 5/8 inches wide and 22 7/16 inches deep. Bosch specifies a required cabinet cutout of approximately 32 1/8 inches high, 17 3/4 inches wide and 24 inches deep. Adjustable feet are provided to help accommodate installation.
This makes the SPX68U55UC especially different from the typical American dishwasher. Most full-size built-in dishwashers are approximately 24 inches wide, whereas this Bosch is designed around an 18-inch opening. The narrow footprint can be valuable in smaller kitchens, but the reduced width naturally means that the interior capacity is lower than that of a full-size 24-inch dishwasher.
Is the Bosch SPX68U55UC an ADA Dishwasher?
The SPX68U55UC belongs to Bosch’s 18-inch ADA/special-application dishwasher family. Bosch’s product literature identifies the SPX68U55UC alongside other 18-inch ADA-oriented 800 Series configurations. Its 32 1/16-inch height is substantially lower than many standard-height dishwashers.
The lower height can be valuable when a kitchen has accessibility requirements or when the cabinetry was specifically designed for a lower dishwasher installation. However, ADA designation should not be interpreted as meaning that every kitchen can accept the appliance without checking measurements. The cabinet opening, countertop height, flooring, door clearance, panel or trim arrangement and plumbing all need to be checked before installation.
The 18-inch format can also make the dishwasher attractive for homeowners who simply do not have room for a conventional 24-inch appliance. In that situation, the SPX68U55UC provides a way to obtain many premium dishwasher features without sacrificing an entire cabinet section to a full-size dishwasher.
Stainless-Steel Exterior and Interior
The SPX68U55UC uses a stainless-steel exterior and stainless-steel tub. The model-specific Bosch specification sheet identifies stainless steel as the tub material and describes the product as an 18-inch 800 Series stainless-steel dishwasher.
A stainless-steel tub is useful in a premium dishwasher because it provides a durable interior and works well with the thermal and moisture conditions associated with dishwasher operation. However, the stainless-steel interior itself should not be interpreted as a guarantee of a particular service life. Maintenance, installation, water chemistry, detergent selection and component wear all influence long-term ownership.
The stainless exterior also gives the SPX68U55UC a conventional appliance appearance rather than the fully integrated cabinetry appearance of Bosch’s custom-panel models. That can make it easier to identify as an appliance and eliminates the need to fabricate a matching cabinet front.
18-Inch Width: The Biggest Advantage and Limitation
The narrow width is arguably the most important characteristic of the SPX68U55UC. At 17 5/8 inches wide, it can fit into spaces where a conventional 24-inch dishwasher simply cannot be installed. Bosch specifies a 17 3/4-inch-wide cutout, making the difference between appliance width and cabinet opening important during installation planning.
For an apartment kitchen, compact kitchen, condo, small house, butler’s kitchen or secondary kitchen, this can be a major practical advantage. A homeowner may be able to gain automated dishwashing without redesigning an entire cabinet run around a standard 24-inch dishwasher.
The trade-off is capacity. The SPX68U55UC is rated for 10 place settings, compared with substantially higher capacities available from many 24-inch dishwashers. For one or two people, or households that run the dishwasher frequently, 10 place settings can be adequate. Larger households may need to run more cycles.
10 Place Settings: Is It Enough?
Bosch rates the SPX68U55UC for 10 place settings. For an 18-inch dishwasher, that is a useful amount of capacity because the narrower cabinet limits the available horizontal loading area.
The third rack helps compensate for the narrower cabinet by creating another loading level for smaller items. Bosch specifically says the third rack provides approximately 30% more loading area compared with a Bosch dishwasher using two racks, and identifies ramekins, cooking utensils and extra-long silverware as examples of items that can be placed there.
For a small household, the combination of 10 place settings and a third rack can be practical. The dishwasher does not need to be enormous if the household produces relatively modest dish loads. However, families that routinely wash large pots, pans and large serving dishes should understand that an 18-inch interior will inevitably provide less loading flexibility than a full-size 24-inch machine.
Third Rack
The SPX68U55UC includes a standard third rack. Bosch designed the third level to add loading flexibility and provide approximately 30% more loading area than a comparable two-rack Bosch configuration.
The third rack is particularly useful for long-handled cooking utensils, flatware and smaller items that can otherwise consume valuable space in the main racks. Bosch specifically identifies ramekins and extra-long silverware as examples of items that can benefit from the additional loading level.
The presence of a third rack is particularly meaningful in an 18-inch dishwasher because every bit of vertical loading capacity matters. Rather than placing every small item into a traditional lower cutlery basket, the user can distribute those items across the uppermost rack.
One point to remember is that this is a standard third rack, not one of the newer flexible third-rack configurations found on some current Bosch models. Buyers comparing the SPX68U55UC with a newer 800 Series dishwasher should examine the exact rack design rather than assuming all 800 Series machines use the same third-rack hardware.
RackMatic Adjustable Upper Rack
The SPX68U55UC uses Bosch’s RackMatic upper-rack system. Bosch specifies three height levels that provide nine possible rack positions.
This is particularly valuable in a compact dishwasher because loading flexibility becomes more important when horizontal space is limited. Raising or lowering the upper rack can create additional room for taller plates, bowls, cookware or glasses depending on how the load is arranged.
The ability to adjust the rack also makes the dishwasher more versatile from one load to another. A load containing tall glasses might require a different rack configuration from a load containing large plates and shallow bowls. RackMatic allows the user to make that adjustment instead of being locked into a single rack position.
Cleaning Performance
The SPX68U55UC uses Bosch’s PrecisionWash approach and a five-level washing system. Bosch describes PrecisionWash as using intelligent sensors and spray arms to monitor the cleaning process and direct water toward the load.
The goal is to avoid treating every dishwasher load as though it has exactly the same soil level. Soil-sensing technology can respond to the conditions inside the dishwasher, making the Auto cycle particularly useful for mixed loads where some dishes are relatively clean while others contain more food residue.
The model also has a concealed heating element. This is significant because Bosch’s dishwasher design uses the heating element beneath the dishwasher interior rather than exposing a traditional heating element across the bottom of the tub. Bosch explains that its concealed-element approach allows plastics to be positioned without the same concern associated with an exposed heating element.
Six Wash Cycles
The SPX68U55UC provides six wash cycles:
- Heavy
- Auto
- Eco
- Normal
- Express
- Rinse
These cycles are documented in the model’s operating instructions.
Heavy Cycle
The Heavy cycle is designed for items with baked-on food or grease that would normally require soaking. This makes it the appropriate choice when cookware or heavily soiled dishes need more aggressive cleaning.
Auto Cycle
The Auto cycle is designed for mixed loads with varying amounts of food soil. The dishwasher uses its soil-sensing capability to adjust operation based on the load. This can make Auto a useful everyday option when you do not want to manually judge how heavily soiled every item is.
Eco Cycle
The Eco cycle lowers temperature and cycle length to reduce energy consumption and is intended for more delicate dishes and glasses. This provides an efficiency-focused option for lighter or less demanding loads.
Normal Cycle
The Normal cycle is intended for everyday loads with typical soil levels. Bosch’s operating instructions describe it as the recommended cycle for regular daily use and normally soiled full loads.
Express Cycle
The Express cycle is intended for lightly soiled dishes and reduces overall wash time. It can be useful when glasses, dessert dishes or other lightly soiled items need to be cleaned relatively quickly.
Rinse Cycle
The Rinse cycle allows users to rinse a partial load and hold those dishes in the dishwasher until enough dishes accumulate for a complete wash. Bosch specifies that detergent should not be used with this cycle.
Five Wash Options
The dishwasher also provides five options:
- Delay Start
- Half Load
- Delicate
- Sanitize
- Extra Shine
These options allow the user to modify certain wash characteristics without having to select a completely different cycle.
Delay Start
Delay Start can postpone the beginning of a dishwasher cycle in one-hour increments for up to 24 hours. This can be useful when users want to run the dishwasher later rather than immediately.
Half Load
The Half Load option is intended for smaller, lightly soiled loads. Bosch describes it as a way to reduce water consumption when the load fills approximately half of the dishwasher’s capacity.
Delicate
The Delicate option lowers the temperature and can reduce the risk of cloudy glasses. It is available only with certain cycles, including Heavy, Auto and Normal.
Sanitize
The Sanitize option is available with Heavy, Auto and Normal cycles. When activated, the dishwasher uses the sanitizing process and provides a sanitized indication when the requirements are met.
Extra Shine
Extra Shine raises the temperature and extends drying time to enhance drying and shine. It is available with wash cycles other than Rinse.
Does the SPX68U55UC Have CrystalDry?
This is one of the most important distinctions to make when reviewing this dishwasher.
The exact SPX68U55UC specification does not list CrystalDry.
Current Bosch 800 Series models prominently advertise CrystalDry, but the SPX68U55UC belongs to an earlier generation whose published specifications identify a concealed heating element, Extra Shine and other drying-related functions rather than CrystalDry.
That means buyers should not purchase the SPX68U55UC expecting the mineral-based CrystalDry system found on newer 800 Series machines. Bosch currently describes CrystalDry as a separate technology that uses natural minerals to transform moisture into heat and claims up to 60% better drying results compared with its PureDry system under its stated testing methodology.
The SPX68U55UC instead provides Extra Shine, which raises temperature and extends drying time to enhance drying performance. That is a legitimate drying feature, but it is not the same technology as CrystalDry.
Drying Performance
The SPX68U55UC can provide effective drying when correctly loaded and operated, but buyers should have realistic expectations because it does not use Bosch’s newer CrystalDry system. The Extra Shine option increases temperature and drying time, giving the user additional control when better drying results are desired.
Plastic items can still behave differently from glass, ceramic and stainless steel because plastics retain less heat and can hold droplets in recessed surfaces. This is a general characteristic of dishwasher drying and is one reason Bosch’s newer CrystalDry technology specifically emphasizes improved plastic drying.
For users who prioritize completely dry plastic containers, a newer Bosch 800 Series model with CrystalDry may offer a different drying system. For users who mainly wash plates, glasses, cups, cutlery and normal cookware, the SPX68U55UC’s conventional drying approach and Extra Shine option may be sufficient.
44 dBA Noise Level
The SPX68U55UC is rated at 44 dBA. Bosch’s model-specific specification identifies 44 dBA as the sound level and markets the dishwasher as part of its quiet 800 Series range.
A 44 dBA dishwasher is designed for relatively quiet operation, making the SPX68U55UC appropriate for kitchens that connect directly to living or dining areas. The lower sound level can also make nighttime operation less disruptive than louder conventional dishwashers.
However, 44 dBA does not mean complete silence. Pumps, water movement, draining and other mechanical sounds can still be audible, and the perceived noise can change depending on cabinet construction, flooring and the surrounding kitchen environment.
The important point is that 44 dBA is a verified specification for this exact model, rather than a number borrowed from a newer Bosch 800 Series dishwasher.
Water Softener
One of the most useful features of the SPX68U55UC is its built-in water softener. Bosch’s model specification explicitly lists water softener: Yes.
This can be particularly useful in areas with hard water. Calcium and magnesium minerals can contribute to spotting, cloudiness and limescale accumulation. A dishwasher water softener reduces the hardness of incoming water according to the appliance’s configured setting, helping support better cleaning and appearance.
The dishwasher uses dedicated dishwasher softening salt. Bosch’s specification identifies SGZ9092UC dishwasher softener salt as an optional accessory for the model. Users should determine local water hardness and follow the appliance instructions rather than adding salt without configuring the system correctly.
For households in hard-water regions of the United States and Canada, this can be a meaningful advantage. It can also be relevant in other regions where mineral-rich water creates dishwasher spotting or scale problems.
Energy Efficiency
The SPX68U55UC is ENERGY STAR qualified, with Bosch’s specification sheet listing 259 kWh of annual energy consumption. The same specification lists 3.0 gallons of water consumption per cycle and approximately 645 gallons of annual water consumption.
The annual energy figure should not be treated as a prediction of every household’s electricity consumption. Standardized dishwasher energy figures are calculated using defined testing conditions and assumptions. Actual consumption varies according to cycle selection, frequency of use, water temperature, options and other conditions.
There is also an important historical context here. Current ENERGY STAR dishwasher criteria allow standard dishwashers up to 240 kWh per year and 3.2 gallons per cycle under the current criteria that became effective in July 2023. The SPX68U55UC’s published 259 kWh figure reflects the certification/testing framework associated with its earlier generation rather than today’s current standard specification format.
Therefore, users should avoid comparing the 259 kWh figure directly with a modern dishwasher’s current EnergyGuide or ENERGY STAR figures without considering the different testing generations and certification rules.
Water Consumption
The SPX68U55UC is specified at 3.0 gallons per cycle, with Bosch listing approximately 645 gallons of annual water consumption.
For a compact dishwasher, this is an important specification because the machine can clean a relatively substantial load while using only a few gallons of water. The water consumption will vary depending on the selected program and options, especially when comparing normal operation with specialized cycles.
The Half Load option is specifically intended to reduce water consumption for smaller lightly soiled loads, which can be useful in households where there are not enough dishes to justify a full load every time.
Five-Level Wash System
The SPX68U55UC has a five-level wash system, according to the model-specific specification. The combination of multiple spray levels and Bosch’s sensing-based PrecisionWash approach is intended to distribute cleaning water throughout the dishwasher rather than relying on a single spray area.
The system becomes especially useful in a compact dishwasher because the interior has to accommodate different shapes and heights of dishes within a smaller footprint. Correct loading remains essential, however, because even a sophisticated spray system cannot properly clean surfaces that are blocked from the water jets.
AquaStop Plus Leak Protection
The SPX68U55UC includes 24/7 AquaStop Plus leak protection. Bosch describes the system as designed to detect leaks and shut down operation while pumping out water to help prevent water from reaching the floor.
This is valuable because a dishwasher is permanently connected to both a water supply and a drain system. Leak detection adds a layer of protection beyond simply relying on the plumbing connection itself.
However, AquaStop should not be treated as a substitute for correct installation. Hoses, connections, drain routing and cabinet penetrations still need to be installed according to the instructions and applicable plumbing codes. Bosch specifically states that plumbing installations vary and should comply with local codes.
InfoLight
The SPX68U55UC includes InfoLight, a small floor-projection indicator designed to show that the dishwasher is operating. Bosch identifies InfoLight as one of the model’s special features.
This is useful because quiet dishwashers can sometimes be so unobtrusive that users cannot tell whether the machine is actually running. A floor indicator provides a quick visual confirmation without requiring the door to be opened.
Installation Dimensions
Installation is one of the areas where buyers need to be especially careful with the SPX68U55UC. Bosch specifies an overall appliance size of approximately 32 1/16 x 17 5/8 x 22 7/16 inches and a required cutout of approximately 32 1/8 x 17 3/4 x 24 inches.
The dishwasher includes adjustable feet, allowing the installer to make height adjustments within the specified installation range. However, Bosch advises that the installation instructions should be consulted for final dimensional information before making the cabinet cutout.
The installation documentation also specifies that the plumbing and electrical connection locations can require a cutout through either the left or right cabinet wall depending on the kitchen layout. This makes pre-installation planning important, particularly in a compact kitchen where there may be less room to reroute utilities.
Electrical Requirements
The SPX68U55UC is specified for 120 volts, 60 Hz and 12 amps, with a rated power consumption of 1,440 watts. Bosch’s specification also identifies a 47 1/4-inch power-cord length.
The exact installation arrangement should follow the supplied installation instructions and local electrical code. Bosch’s documentation provides both receptacle and hardwire installation examples and specifies that electrical connection locations need to be planned around the cabinet opening.
Because the model is built around North American electrical specifications, the exact SPX68U55UC should not be treated as a universal international appliance.
USA Compatibility
For the United States, the SPX68U55UC is a North American 120 V/60 Hz dishwasher and is documented through Bosch’s U.S. product and support system. Bosch’s current product page now identifies the model as no longer available, but support remains available for multiple model revisions.
This means that buyers considering a used, remaining-stock or replacement-unit SPX68U55UC should pay particular attention to the exact revision number. Bosch lists multiple versions, including /23, /28, /29, /30, /32, /33, /37, /42, /45, /51 and /58.
For replacement parts or troubleshooting, identifying the complete model number and revision is therefore important. Different production revisions can have different documentation and component information even though the base model name remains SPX68U55UC.
Canada Compatibility
The model’s 120 V/60 Hz electrical specification is consistent with the general residential electrical supply used in Canada. Historical warranty documentation for this dishwasher family also covers qualifying purchases made in the United States or Canada, subject to the conditions of the applicable warranty.
Canadian buyers should nevertheless verify local availability and the warranty associated with the specific unit being purchased. Because the model is discontinued in the current U.S. product catalog, a Canadian unit may be remaining inventory or an older product rather than a currently produced model.
UK Compatibility
The exact SPX68U55UC should not be treated as a normal UK installation model. Its electrical specification is 120 volts and 60 Hz, whereas standard UK household electrical service uses a different voltage and frequency configuration.
UK readers can still use this review to understand the dishwasher’s design, rack system, capacity, cleaning approach, noise level and other features, but the exact North American SPX68U55UC should not be installed on a standard UK electrical supply simply because the physical dimensions appear suitable.
For a UK kitchen, a locally specified Bosch 18-inch or compact dishwasher designed for the applicable electrical system should be selected instead.
Warranty
Bosch’s current U.S. general dishwasher warranty provides one year of limited coverage for the complete appliance, parts and labor. It also lists additional limited coverage for electronics and racks from the second through fifth years and lifetime limited coverage for rust-through of specified stainless-steel components, subject to the applicable warranty terms.
The historical SPX68U55UC warranty documentation provides additional model-generation context, including a one-year warranty and extended limited coverage for electronics and dish racks, plus lifetime rust-through coverage for the stainless-steel tub and door under the stated conditions.
Warranty coverage should always be checked against the documentation supplied with the actual unit because the SPX68U55UC has been produced in multiple revisions and is no longer listed as a current U.S. product.
Repair and Parts Support
Even though the SPX68U55UC is no longer available as a current product, Bosch maintains model-specific support pages for numerous revisions. Those pages provide access to manuals, installation instructions, specification sheets, energy documentation and parts-related resources.
Bosch also states that its authorized technicians and service providers are trained to service its large appliances and use original Bosch parts. This is relevant for an older dishwasher because access to correct replacement parts and technical documentation can be as important as the original purchase price.
For anyone considering a used SPX68U55UC, checking parts availability before purchase is sensible. The existence of model-specific support is encouraging, but discontinued status means buyers should not assume every component will remain available indefinitely.
Common Problems to Watch For
A dishwasher of this age and complexity can develop issues involving filters, pumps, hoses, heating components, water-softening equipment, sensors or electronic controls. This does not establish that the SPX68U55UC is inherently unreliable; it simply reflects the fact that a used appliance has accumulated operating time. Bosch continues to provide troubleshooting and maintenance resources for dishwasher owners.
Hard-water buildup is one area that deserves particular attention. Because the SPX68U55UC includes a water-softening system, owners in hard-water regions should make sure the softener is correctly configured and supplied with the appropriate dishwasher salt. Failure to manage water hardness can contribute to spotting and mineral accumulation.
Drainage problems can also occur when filters or drainage areas become blocked with food debris. Regular cleaning and inspection are therefore important, especially on older machines. Bosch provides dedicated dishwasher cleaning, maintenance and troubleshooting resources for these situations.
Is the SPX68U55UC Reliable?
There is no responsible way to guarantee a specific lifespan for an individual SPX68U55UC. Appliance life depends on installation quality, frequency of use, water conditions, maintenance, component wear and repair history.
Independent testing information is also important to interpret correctly. Consumer Reports currently has a page for the SPX68U55UC but states that it expects the model to perform similarly to the tested Bosch 300 Series SPE53U55UC while noting that features and price may differ. The full model-specific Consumer Reports scores are behind its membership access, so a precise independent lab score should not be invented from the publicly visible information.
This is an important distinction when researching an older dishwasher. Manufacturer specifications tell us what the machine was designed to provide, while independent testing can provide performance information. Where a complete independent score is not publicly available, it is better to state that limitation than to manufacture a numerical rating.
SPX68U55UC vs Newer Bosch 800 Series
The SPX68U55UC should not be confused with today’s current 800 Series models. Bosch’s current 800 Series lineup prominently features CrystalDry and PowerControl, with some current models rated at 42 dBA.
The SPX68U55UC is an earlier 800 Series design. Its exact documentation specifies 44 dBA, PrecisionWash, a five-level wash system, standard third rack, RackMatic, water softener, Eco Cycle, InfoLight and Extra Shine rather than CrystalDry and PowerControl.
That does not mean the older dishwasher is automatically inferior for every user. The SPX68U55UC has a feature combination that remains attractive, especially because it is an 18-inch machine. The newer 800 Series may have more advanced drying and cleaning technology, but if a kitchen physically requires an 18-inch dishwasher, the comparison is not simply about features; physical compatibility becomes equally important.
SPX68U55UC vs a Standard 24-Inch Dishwasher
The biggest difference is physical capacity. A conventional 24-inch dishwasher has more horizontal interior space and generally offers more room for large plates, cookware and serving dishes. The SPX68U55UC sacrifices some of that capacity in exchange for its compact footprint.
The third rack and RackMatic system help make the most of the available space. The third rack provides additional loading area, while RackMatic offers nine possible upper-rack positions. These features are especially useful in an 18-inch appliance because efficient vertical loading becomes more important when width is restricted.
For a small household, the capacity may be perfectly reasonable. For a family that cooks large meals daily, a 24-inch dishwasher will generally provide more physical loading capacity simply because there is more interior volume.
Pros of the Bosch SPX68U55UC
1. Compact 18-Inch Width
The narrow 17 5/8-inch appliance width is the biggest advantage for kitchens that cannot accommodate a standard dishwasher.
2. 800 Series Features
Despite its compact size, the dishwasher includes several premium features, including PrecisionWash, a third rack, RackMatic, a water softener and AquaStop Plus.
3. Quiet 44 dBA Operation
The 44 dBA rating makes it appropriate for open-plan kitchens and households where dishwasher noise matters.
4. Third Rack
The third rack creates additional loading space and is useful for long utensils, ramekins and extra-long silverware.
5. RackMatic
Three rack heights and nine possible rack positions provide useful flexibility in a compact interior.
6. Water Softener
The built-in water softener is a valuable feature in hard-water areas and can help reduce mineral-related spotting when correctly configured and maintained.
7. AquaStop Plus
24/7 AquaStop Plus provides an additional layer of protection against water leaks.
8. ENERGY STAR Qualified
The model was ENERGY STAR qualified under its applicable certification framework and specifies 3.0 gallons per cycle.
9. Multiple Cycles
Six cycles cover heavy, automatic, economical, normal, express and rinse requirements.
10. Sanitize Option
The dishwasher includes a dedicated Sanitize option, and NSF/ANSI 184 certification is the relevant residential standard for validating dishwasher sanitization performance when the certified cycle is used.
Cons of the Bosch SPX68U55UC
1. Only 18 Inches Wide
The compact size is an advantage only if you need it. For a household with space for a 24-inch dishwasher, the smaller interior can be a capacity limitation.
2. Only 10 Place Settings
Ten place settings can be adequate for a small household but may require more frequent cycles for larger families.
3. No CrystalDry
The exact SPX68U55UC documentation does not list CrystalDry. Buyers specifically seeking Bosch’s mineral-based advanced drying technology should look at newer models.
4. No PowerControl
PowerControl is a feature associated with newer Bosch 800 Series models, but it is not listed for the SPX68U55UC.
5. Discontinued in the Current U.S. Catalog
Bosch’s current U.S. product page identifies the SPX68U55UC as no longer available.
6. North American Electrical Specification
The exact model is designed around 120 V/60 Hz service, so it is not a normal direct-installation dishwasher for a standard UK electrical supply.
Who Should Consider the Bosch SPX68U55UC?
The SPX68U55UC makes the most sense for someone who specifically needs an 18-inch dishwasher but does not want to compromise on premium features. The third rack, RackMatic adjustment, water softener, PrecisionWash, quiet operation and AquaStop Plus give the machine a feature set that goes well beyond the most basic compact dishwashers.
It can be particularly appropriate for one- or two-person households, compact kitchens, apartments, condos and accessibility-focused kitchen installations where a 24-inch dishwasher would be impractical. The 10-place-setting capacity provides a reasonable balance between compact dimensions and useful loading space.
It is less attractive for someone who has ample room for a 24-inch dishwasher and prioritizes maximum capacity. In that situation, the larger dishwasher format provides more room for large cookware and serving dishes.
Who Should Avoid It?
A buyer who specifically wants CrystalDry should look at newer Bosch models because the SPX68U55UC does not list that technology. Bosch’s current 800 Series lineup uses CrystalDry on applicable models and advertises up to 60% better drying results under its specified testing methodology.
Similarly, a buyer who specifically wants PowerControl should compare newer 800 Series models. Bosch’s current 800 Series range identifies PowerControl as a newer spray-arm technology, whereas the SPX68U55UC specification does not list it.
A household that routinely produces large amounts of dishes may also be better served by a 24-inch dishwasher if the kitchen has enough space. The SPX68U55UC’s compact dimensions inherently limit its total loading volume.
Maintenance Tips for SPX68U55UC Owners
Regular maintenance is important for keeping the dishwasher operating properly. Filters should be inspected and cleaned so that food debris does not interfere with drainage or cleaning performance. Bosch provides dedicated dishwasher maintenance guidance covering filters, cleaning and general care.
The spray system should also be kept clear of food particles and mineral deposits. Blocked spray openings can reduce water distribution and contribute to poor cleaning results.
Hard-water users should pay special attention to the water-softening system. The dishwasher should be configured according to local water hardness and supplied with the appropriate softener salt when required.
Owners should also inspect the dishwasher for unusual leaks, drainage problems or changes in cleaning performance. Early attention to unusual behavior can prevent a relatively small maintenance issue from becoming a larger repair.
Loading Tips for Better Results
The SPX68U55UC’s compact size makes loading technique particularly important. Dishes should be positioned so that water can reach the surfaces that need cleaning. Large plates should not block spray patterns, and bowls should be positioned so that dirty surfaces are exposed to the water jets.
The third rack should be used for suitable flatware, utensils and smaller items rather than overloaded with objects that block water flow. Bosch specifically designed the rack for items such as ramekins, cooking utensils and long silverware.
The RackMatic upper rack should be adjusted according to the load. Raising it can create additional clearance for tall items below, while lowering it can provide additional vertical space for items positioned in the upper rack.
Pre-rinsing every dish is generally unnecessary with a modern sensor-equipped dishwasher. Removing large pieces of food is sensible, but washing every plate under running water before loading wastes water and reduces some of the efficiency benefits of automated dishwashing.
Is the Bosch SPX68U55UC Worth Buying Today?
The answer depends heavily on why you want this particular model.
If you need an 18-inch dishwasher and find a properly maintained SPX68U55UC at a reasonable price, its combination of Bosch 800 Series features remains interesting. The water softener, third rack, RackMatic, PrecisionWash, quiet 44 dBA operation and AquaStop Plus are meaningful features for a compact dishwasher.
If you are buying a brand-new dishwasher and have room for a newer model, however, the fact that Bosch now lists the SPX68U55UC as no longer available deserves consideration. Newer products may offer updated drying, cleaning, rack and connectivity technologies.
The best use case for the SPX68U55UC is therefore not simply “anyone looking for a Bosch 800 Series dishwasher.” It is specifically the buyer who needs a compact 18-inch, lower-height Bosch dishwasher with premium features.
Final Bosch SPX68U55UC Review
The Bosch 800 Series SPX68U55UC is a compact dishwasher with a surprisingly comprehensive specification. Its 18-inch width is its defining feature, but Bosch has packed the appliance with several technologies associated with its higher-end dishwasher range, including PrecisionWash, a five-level wash system, RackMatic, a third rack, a water softener, AquaStop Plus and InfoLight.
The 10-place-setting capacity is appropriate for an 18-inch dishwasher, and the third rack helps make better use of the limited interior volume. RackMatic’s three height levels and nine possible positions provide additional flexibility, which is especially valuable in a compact appliance.
The 44 dBA noise rating is another strong characteristic. It makes the SPX68U55UC suitable for open-plan kitchens and homes where a dishwasher needs to operate without creating excessive background noise.
The built-in water softener is also an important feature for hard-water households. Proper water-hardness configuration and dishwasher salt use can help reduce mineral-related spotting and scale.
The main technology limitation compared with current Bosch 800 Series models is that the SPX68U55UC does not have CrystalDry or PowerControl according to its exact specification. Its drying enhancement comes through Extra Shine, while its cleaning platform uses PrecisionWash rather than the newer PowerControl system.
Another important consideration is availability. Bosch’s current U.S. product page identifies the SPX68U55UC as no longer available, although Bosch still provides model-specific documentation and support for numerous revisions.
For USA and Canada buyers, the model’s 120 V/60 Hz electrical specification is appropriate for the North American environment, subject to local installation requirements. UK buyers should treat the review as a technical reference rather than a recommendation to install this exact North American model because its electrical specification is not designed for standard UK household supply.
The overall picture is therefore clear: the SPX68U55UC is most compelling when 18-inch width, compact capacity and premium Bosch features are the primary requirements. If maximum capacity, CrystalDry or the newest 800 Series cleaning technology is more important, a newer and larger Bosch model may have a different feature set.

Can the SPX68U55UC be used in Canada?
Its 120 V/60 Hz electrical specification is consistent with the general residential electrical environment in Canada. Buyers should nevertheless verify the exact unit’s market availability, warranty and installation requirements. Historical warranty documentation for this model family covers qualifying U.S. and Canadian purchases under stated conditions.
Is the Bosch SPX68U55UC still available?
Bosch’s current U.S. product page identifies the SPX68U55UC as no longer available. Bosch does, however, continue to provide support resources for multiple revisions of the model.
Can I still get parts for the SPX68U55UC?
Bosch maintains model-specific support pages with manuals, specification documents and parts-related resources for multiple SPX68U55UC revisions. Availability of individual parts can change over time because the model is discontinued.
What warranty did the SPX68U55UC have?
The applicable Bosch warranty documentation provides one year of standard limited coverage, with additional limited coverage for specified electronics and racks and lifetime limited rust-through coverage for specified stainless-steel components under the stated conditions. Current warranty terms should be checked against the actual unit’s documentation.
Is the SPX68U55UC better than a 24-inch dishwasher?
That depends on the kitchen. The SPX68U55UC has the advantage when an 18-inch dishwasher is required, but a 24-inch dishwasher provides more interior capacity. The SPX68U55UC is therefore primarily a solution for compact spaces rather than a direct capacity replacement for a full-size dishwasher.
Is the Bosch SPX68U55UC worth buying used?
A used SPX68U55UC can make sense when an 18-inch dishwasher is required and the unit is in good condition. Buyers should inspect the racks, pump operation, water-softening system, hoses, door seals and electronic controls and should verify parts availability for the exact revision before purchasing.
What are the biggest advantages of the SPX68U55UC?
Its biggest advantages are the compact 18-inch width, quiet 44 dBA operation, third rack, RackMatic adjustment, water softener, PrecisionWash, six wash cycles and AquaStop Plus leak protection.
What are the biggest disadvantages?
The main disadvantages are the smaller 10-place-setting capacity, lack of newer CrystalDry and PowerControl technologies, North American electrical specification and discontinued current U.S. status.
Final Takeaway
The Bosch SPX68U55UC remains an interesting compact 800 Series dishwasher, particularly for kitchens where an 18-inch width is essential. Its premium rack system, water softener, PrecisionWash, quiet 44 dBA operation and AquaStop Plus make it considerably more sophisticated than many compact dishwashers.
Its limitations are equally clear: it is an older-generation model, it does not have CrystalDry or PowerControl, it holds 10 place settings rather than the capacity of a full-size dishwasher, and Bosch now identifies it as no longer available in the U.S.
For someone who specifically needs a narrow dishwasher, those limitations may be acceptable. For someone with room for a modern 24-inch dishwasher, newer Bosch models may offer substantially different technology and greater capacity. The right comparison therefore depends first on the kitchen’s physical requirements and then on the desired feature set.
