Whirlpool WDP370PAHB Portable Dishwasher vs Whirlpool WDTA50SAKZ Dishwasher

The WDTA50SAKZ is the better dishwasher for most people.

The WDP370PAHB is a portable unit on wheels that hooks to the kitchen faucet, so it suits renters or kitchens with no built-in slot. Owners rate the built-in higher, 4.6 from over 7,000 ratings against 4.4 from 742.

Questions and answers

Which is better for a rental kitchen?
The WDP370PAHB. It is portable and hooks to the faucet, so you can take it with you and leave the cabinets alone. The WDTA50SAKZ needs a permanent built-in installation.
Which one is quieter?
The WDTA50SAKZ at 47 dBA. The WDP370PAHB is listed at 55 dB, with a 64 dB noise level also listed, so it is noticeably louder in an open kitchen.
Is the third rack worth stepping up for?
Yes if you cook with long utensils and lids. The cutlery tray on the WDTA50SAKZ frees space in the lower racks, and the extra place setting helps on big loads.
Which holds more dishes?
The WDTA50SAKZ holds 13 place settings against 12 for the WDP370PAHB, and its third rack adds room for cutlery and small items.
Does either one have smart features?
No. Neither connects to an app or voice assistant. Both offer a delay start and a Quick Wash cycle.
Which lasts longer?
The WDTA50SAKZ has a stainless steel tub, which generally resists staining and holds up better over years of use. The WDP370PAHB uses a plastic tub and is built to be moved.
