Looking for help to diagnose a Whirlpool undercounter dishwasher. The unit will not auto drain and then overflows on the floor but only on some of the settings.
When you press “CANCEL/ DRAIN” it drains fine. Thought maybe the float switch, but why would it work ok on some settings?
Please help.
Hi.
The problem you described could be caused by the defective control board
Or bad float switch assembly.
