KitchenAid and Bosch have been trading positions on Consumer Reports' dishwasher rankings for years, and these two models — the KDPM604KPS and SHE89PW75N — represent each brand's mid-premium offering around $1,100. Both are quiet, both have third racks, and both clean extremely well. The differences are real but narrow enough that your choice might reasonably come down to which brand matches your other appliances.
Bosch 800 Series SHE89PW75N
The Bosch SHE89PW75N edges ahead on quiet operation and drying performance; the KitchenAid KDPM604KPS wins on rack capacity and washing flexibility.

Cleaning and Wash System Comparison
Consumer Reports rated both machines 'Excellent' for washing performance. KitchenAid's ProWash cycle uses sensors to detect soil levels and automatically adjusts water temperature, cycle time, and pressure. The KDPM604KPS is particularly strong on baked-on soil — KitchenAid's high-pressure lower spray arm targets the bottom rack more aggressively than Bosch's rotor-based system.
Bosch's PrecisionWash also uses sensors and a multi-stage wash approach, but its design philosophy prioritizes even coverage across all racks rather than targeting the bottom specifically. For mixed loads with items on all three racks, Bosch's even-pressure system performs marginally better in Consumer Reports' whole-load tests.
Practically: if you load heavily soiled pots on the bottom and lighter items above, the KitchenAid's targeted lower-rack pressure is an advantage. For evenly distributed everyday loads, the Bosch's consistent coverage wins.
Drying: KitchenAid ProDry vs Bosch CrystalDry
KitchenAid's ProDry system uses a heated dry element and fan to force dry. It performs well on all material types, including plastics. Consumer Reports rated KitchenAid's drying 'Excellent' across all load types.
Bosch's CrystalDry on the SHE89PW75N routes humid air through a zeolite mineral layer that converts moisture to heat — delivering excellent drying without a traditional heating element. Consumer Reports found CrystalDry's plastic drying especially impressive, often better than heated dry on fragile items.
Owners on r/Appliances frequently cite CrystalDry as the feature that tips them toward Bosch once they've seen it in action. The KitchenAid's heated dry is excellent but uses more energy and can warp thin plastics on rare occasions.
Noise and Third Rack Design
The Bosch SHE89PW75N is rated at 40 dBA — quieter than the KitchenAid KDPM604KPS's 44 dBA. Neither rating is loud in any meaningful sense, but Bosch's 4 dBA advantage is perceptible in a silent kitchen.
Both machines have a third rack, but their implementations differ. KitchenAid's third rack is deeper and can hold full-size spatulas and serving utensils flat. Bosch's third rack is shallower and optimized for small items — espresso cups, lids, and cutlery laid flat. Which design serves you better depends on what you regularly wash.
KitchenAid's interior capacity is slightly larger overall. If you regularly run large loads with tall items, KitchenAid's extra vertical clearance in the lower rack is a genuine edge.
Reliability and Price
Yale Appliance reliability data shows Bosch dishwashers consistently outperforming KitchenAid (Whirlpool Corp.) on service call rates. Both brands are above industry average, but Bosch's manufacturing precision gives it a measurable edge in first-year service data.
The KitchenAid KDPM604KPS MSRP is $1,149. The Bosch SHE89PW75N lists at $1,199. Sale pricing regularly pulls both under $1,000. At price parity, Bosch's reliability data and CrystalDry technology edge it ahead. When KitchenAid is $100–$150 cheaper on sale, the calculus tightens considerably.
Both come with 1-year parts and labor warranties. KitchenAid's service network through Whirlpool is larger in rural areas; Bosch service is more concentrated in urban markets.
KitchenAid KDPM604KPS Strengths
- Deeper third rack accommodates full-size spatulas and cooking utensils laid flat
- Targeted lower-rack wash pressure handles baked-on soil better on heavily loaded bottom rack
- Whirlpool service network is larger and faster in rural and suburban markets
Bosch 800 Series SHE89PW75N Strengths
- 40 dBA — 4 dBA quieter than KitchenAid's 44 dBA at the same price bracket
- CrystalDry zeolite drying is best-in-class for plastics without a heating element
- Lower service rate per Yale Appliance reliability data for matched price tier
KitchenAid KDPM604KPS Weaknesses
- 44 dBA — noticeably louder than Bosch's 40 dBA at similar price points
- Heated dry uses more energy than CrystalDry; risk of warping thin plastics at high temps
- Higher first-year service rate than Bosch per Yale Appliance data
Bosch 800 Series SHE89PW75N Weaknesses
- Shallower third rack — limited to small items, not full cooking utensils
- Bosch service technicians less available in rural areas vs Whirlpool/KitchenAid network
- PrecisionWash is less aggressive on heavily soiled bottom-rack loads than KitchenAid's targeted spray
Best For
- a: Households that cook heavily and load big pots and utensils, or buyers in rural areas where KitchenAid/Whirlpool service is faster
- b: Anyone prioritizing the quietest possible machine and best plastic-drying performance in this price range
FAQ
Does CrystalDry actually work on plastic Tupperware?
Yes — and this is where Bosch users become evangelists. The zeolite mineral absorbs moisture and releases heat, drying plastic containers reliably without warping risk. Consumer Reports confirmed Bosch's CrystalDry outperforms heated dry on plastics.
Can I get KitchenAid's third rack design in a Bosch?
No — Bosch's shallow third rack is a fixed design choice across their lineup. If loading large spatulas and serving spoons flat is important to you, KitchenAid is the better fit.
How long do these machines typically last?
Both are designed for 10+ years in normal residential use. Consumer Reports' projected reliability survey data puts both brands in the top half of the category. Bosch edges slightly ahead on 5-year reliability, but either machine should reach 10–12 years without major issues.
