Exact questions
Questions that only have an answer for the KitchenAid KDTE304 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.
My KitchenAid KDTE304 smells musty.+
Odour is the filter and trapped food. Rinse the manual filter at the bottom of the tub, wipe the tub floor and door gasket, and run a hot cycle with a dishwasher cleaner. Scrape plates before loading and leave the door ajar between uses so the tub dries. If water stands in the tub, that partial-drain water also smells — clean the filter and check the drain path.
