Whirlpool WDTA50SAKZ Dishwasher vs Whirlpool WDT740SALW Built-In Dishwasher

Both are Whirlpool built-in dishwashers with stainless tubs and five cycles, so the real split is noise and capacity versus layout. The WDT740SALW is the quieter machine on paper and fits one more place setting, which suits open-plan kitchens and larger households. The WDTA50SAKZ adds a third cutlery tray and an adjustable second rack, which helps with awkward utensils and tall items. Owners of both lines report solid cleaning and few repairs; the trade-off is that the quieter model gives up the flexible third-rack layout.

• Choose the WDTA50SAKZ if you want a third rack for cutlery and an adjustable middle rack for tall pots and stemware.
• Choose the WDT740SALW if a quieter run and one extra place setting matter more than a third rack.
