The Bosch 800 Series SHX78CM5N is the dishwasher most worth buying if you can spend around $1,300. It pairs the best wash and drying performance in its class with one of the quietest cabinets you can put in an open-plan kitchen, and Bosch's reliability record continues to put it near the top of any service-rate chart that includes the major US brands.
Full review
Cleaning Performance and Real-World Use
Reviewed's lab put the 800 Series through its full cycle bench and measured 99.97% cleaning on the Heavy cycle and 95.73% on Normal — numbers that put it within striking distance of the best machines they have ever tested, and well ahead of the average dishwasher's low-90% Normal-cycle result. Consumer Reports separately classifies it 'very good' for washing heavily soiled dishes and notes the model removes stubborn baked-on stains better than nearly every competitor in its class.
In practice that performance comes from the PowerControl spray arm with PrecisionWash, which lets you bias the lower zone toward a Heavy spray pattern without putting the whole load through a Heavy cycle. Sensors check soil levels mid-wash and extend or shorten cycles based on what they see, so a lightly soiled glass-and-bowl load actually finishes in a reasonable time even on Auto.
Noise Level and Open-Floor-Plan Use
At 42 dBA this is quiet enough that Consumer Reports rates the model 'excellent' for noise after combining sound-level measurements with listener judgments. Bosch's own marketing line — quieter than a library conversation — is unusually close to true for an appliance spec. In a kitchen that opens onto a living room, you can run the dishwasher with a TV at normal volume on the other side of an island and barely notice it.
The 800 Series is also one of the few sub-$1,500 dishwashers where the second-loudest noise — the drain pump — was deliberately tuned down. That matters because most dishwashers spec their dBA at the quietest minute of the cycle; Bosch's number is closer to what you actually hear at the loudest minute.
Drying Performance and CrystalDry
CrystalDry is Bosch's branding for a zeolite mineral chamber that absorbs moisture from the cabinet air during the dry phase and releases the heat back into the tub. Reviewed describes dishes coming out 'bone-dry, cupboard-ready' and singled out plastics — historically the hardest item to dry without an electric heating element — as where the system shines. Yale Appliance lists this as the 800 Series' standout feature when comparing it to Miele, whose condensation drying delivers 'a little better drying but not as good as the Bosch 500'.
The trade-off is cycle time: the dry phase adds 15 to 30 minutes versus a heated-rod dryer, but the difference is reclaimed in less re-toweling on plastic lids and reusable food containers.
Build Quality and Reliability
Bosch's 12-month service rate sits around 7.8% in Yale Appliance's 33,000+ call dataset, which is among the lowest in the US market — better than KitchenAid, Samsung, GE, LG, and well below the industry average. Miele still beats Bosch on this metric (5.6%), but a Bosch 800 is roughly half the price of an equivalent Miele G7000 model.
The build itself is the standard Bosch story: a stainless tub, EasyGlide rack rollers that don't sag once a year, and a quality of fit-and-finish on the door handle and control board that you simply don't get from the value brands. Most of the negative long-term reviews concentrate on the touch control board, which has the highest failure rate of any single part on this machine.
Smart Features and the Home Connect App
Home Connect is the right kind of smart-appliance app: it monitors cycle progress, lets you start, pause, or delay a cycle remotely, and sends a push notification when the load is done. It integrates with Alexa and Google for voice control, and Bosch ships software updates over the air so the dishwasher gets new cycle options after purchase.
The catch is that several features Bosch puts on the marketing sheet — adjustable wash zone targeting, custom temperature programming, the in-cycle Delay Wash override — only exist in the app. The on-cabinet touch controls cover the basic 8 cycles and a few options, but anything more nuanced sends you to your phone.
Where It Falls Short
Reviewed calls the touch controls 'finicky' and notes they sometimes need two taps to register, which is the most common complaint in long-term owner forums. The hidden top-control design also means there's no clear visual indicator that a cycle is running unless you use the InfoLight floor projection feature.
Cycle time on the Normal program runs about 2 hours and on Heavy about 2 hours 5 minutes — competitive at this price point, but slow if you run two loads back-to-back on a busy night. The 1-hour Speed60 cycle cleans 97.11% of stains in lab testing, which is the right escape hatch, but you pay for it in water and energy.
Who It's Best For
Buy the 800 Series SHX78CM5N if you want the best-in-class drying for plastic food storage, an open-plan kitchen where dishwasher noise actually matters, and you can spend around $1,300 without stretching to a Miele. It's the default 'best built-in dishwasher most people should buy' on essentially every editorial round-up in 2026, and the choice is hard to argue with.
Skip it if you specifically need an under-cabinet panel-ready unit (the SHX is bar-handle stainless only — look at the Bosch Benchmark SHP9PCM5N for panel-ready) or if 1-year parts-and-labor warranty is a dealbreaker; Miele includes longer coverage at its higher price point.
How It Compares to Alternatives
Against the Miele G 7266 SCVi: the Bosch is $650 cheaper, cleans roughly as well, and beats the Miele on plastic drying. The Miele wins on long-term reliability (5.6% vs 7.8% service rate) and on the AutoOpen door that boosts dish drying further. If you keep appliances 15+ years, the Miele math eventually works.
Against the KitchenAid KDTM604KPS: the Bosch is 2 dBA quieter, dries plastics better, and has a better-built touch panel. The KitchenAid wins on its FreeFlex Third Rack, which is genuinely the largest third rack in any consumer dishwasher and includes its own wash jets. Against the LG LDTH7972S: the Bosch is quieter and dries better; the LG counters with TrueSteam loosening and a deeper feature set per dollar.
Energy Use and Operating Cost
The SHX78CM5N is Energy Star certified and uses an average of 3.2 gallons per Normal cycle, near the bottom of the consumption range for a 16-place-setting dishwasher. Consumer Reports rates it 'very good' on energy testing — their measure combines water usage and electricity consumed for a fully soiled load. Estimated annual electricity cost at the US average power rate runs about $35-$40 per year for typical household use.
Bosch's PrecisionWash sensors materially help here: by adapting cycle length to actual soil rather than running a fixed-time Heavy cycle every time, the machine routinely shaves 15-30 minutes off cycles that other dishwashers would run for the full duration. Over a year that translates to real water and energy savings, particularly versus the budget builds that don't include soil sensors at all.
Installation Notes for Renovators
The SHX78CM5N is a top-control model with a bar handle, which means the cycle controls are hidden on top of the door rim and the only thing visible from outside is the stainless face and the handle. The standard 24-inch width and 33-7/8-inch height fit any standard US dishwasher cabinet opening, and Bosch ships an adjustable kickplate for cabinets that aren't quite to spec. The InfoLight feature projects a red dot onto the floor while a cycle is running so you don't accidentally open the door mid-wash.
If you want a flush integrated panel matching your cabinets, look at the SHP version instead (same internals, pocket handle, panel-ready). The SHX is the right pick for a straightforward stainless replacement install where you don't want to coordinate cabinet panel work. Bosch also includes EasyGlide rack rollers and adjustable height tines on both upper and middle racks, both of which materially improve loading on day one and continue to work years later.
Strengths
- +42 dBA noise level is among the quietest in any built-in dishwasher under $1,500
- +CrystalDry zeolite system delivers genuinely dry plastics that most competitors leave wet
- +PrecisionWash with PowerControl spray arm targets dirtier zones without a full Heavy cycle
- +Flexible 3rd rack with adjustable middle rack swallows utensils, lids, and 6-inch stemware
- +Independent labs measured 99.97% cleaning on the Heavy cycle, near the top of the entire test set
Watch-outs
- −Touch controls can feel finicky and several useful options live only in the Home Connect app
- −Normal cycle runs around 2 hours, which feels slow if you only run one load a day
- −Bar-handle SHX variant ships only in stainless; no panel-ready option at this price
How it compares
Cleans as well as the Miele G 7266 SCVi and the KitchenAid KDTM604KPS at a noticeably lower price than the Miele. Drying is a real step above the LG LDTH7972S because of CrystalDry, especially on plastic containers. Quieter than the KitchenAid KDTM604KPS by 2 dBA, and much quieter than the Farberware FCD06ABBWHA countertop unit. Lacks the AutoOpen door of the Miele but the zeolite drying largely compensates.
