Exact questions

Questions that only have an answer for the KitchenAid KDTM804 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 KDTM804 cycle runs very long.+

Long cycles are normal on the Auto/ProWash and heavy modes — the sensor tests soil and adjusts, and ProDry adds heated drying time, for a thorough result. Use a one-hour or express cycle when you do not need the full clean. If it seems to hold at one time, that is usually the sensor waiting while it heats water; a hotter incoming supply shortens it.
