Published specification
What is true of this model and changes how you fix it
These are the properties that decide which procedure applies. Each is read from the manufacturer’s own published figures for this model, not carried over from a sibling that shares its retail name.
- Drying — ProDry (fan + heating element)
- KitchenAid's ProDry uses a heating element AND a fan for strong drying, including plastics — much stronger than Bosch condensation. Keep plastics off the tub floor to avoid melting on the element, and keep rinse aid filled. If dishes are wet, confirm ProDry/heated dry is selected.
- Wash & racks
- Premium stainless tub, a FreeFlex 3rd rack, and a very quiet operation. A manual filter at the tub floor must be cleaned periodically.
- Drain path
- 'Won't drain' is usually the filter, drain hose, air gap, or an un-removed disposer knockout plug. KitchenAid is Whirlpool-built, so Whirlpool-style parts and logic apply.

Exact questions
Questions that only have an answer for the KitchenAid KDTM604 dishwasher
Each answer below uses this model’s own published figures. The same question asked about a different model in the line has a different answer, which is why it is answered here rather than on a general page.
How well does my KitchenAid KDTM604 dry plastics?+
Well — KitchenAid's ProDry uses a heating element plus a fan, so it dries plastics far better than a condensation-only dishwasher like a Bosch. Make sure the ProDry/heated-dry option is selected and the rinse-aid tank is filled. The trade-off of having an element is that a plastic item that falls onto the tub floor can melt against it, so keep plastics on the racks.
