Higher ratedRanked #1 in Best Dishwashers

Bosch 800 Series SHX78CM5N

4.8

$1,349

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.

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

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

Ranked #3 in Best Dishwashers

LG LDTH7972S

4.4

$949

The LG LDTH7972S is the value pick that doesn't feel like one. At $949 it matches the Bosch 800 Series on noise (42 dBA), beats most everything in its class on warranty depth, and is the only machine in this comparison with a true steam generator. The lower rack has a documented cleaning dead-zone, but on the Heavy cycle with TrueSteam the LG removes over 99% of stains.

Strengths

— 42 dBA noise level matches the Bosch 800 Series at $400 less
— TrueSteam loosens baked-on food before the main wash, raising Heavy-cycle cleaning past 99%
— 10-year warranty on the direct-drive motor and 2 years on the stainless tub and racks — one of the deepest warranty stacks in the segment

Watch-outs

— Bottom-center of the lower rack can leave heavier stains during Normal cycles (Reviewed measured up to 70% residual staining there in testing)
— Plastics still require a wipe after the dry cycle despite the Dynamic Heat Dry fan
— Only 1 year on parts and labor — the deeper warranties are on specific components

How they stack up

Bosch 800 Series SHX78CM5N

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.

LG LDTH7972S

The single best value built-in in this comparison — matches the Bosch 800 SHX78CM5N on dBA and on Wi-Fi at $400 less. The Bosch and Miele G 7266 SCVi both clean more consistently across the full lower rack; the LG has a documented dead zone at the back-center bottom. Wins decisively over the KitchenAid KDTM604KPS on warranty depth (10-year motor coverage) and on cycle count (10 vs 5). Much louder and cycle-quicker than the Farberware FCD06ABBWHA countertop, as expected for a built-in.
