Customer Questions and Answers for Dishwasher Door Switch by Whirlpool

Hello Chris. Turn off the dishwasher in stand by mode (no lights on control panel). Press heated dry, Normal, Heated dry, Normal and the dishwasher will start. Let it run through the complete cycle. Always get the water hot at the sink before starting the dishwasher. If the problem continues, you will need to test the heater WPW10082892 and the thermostat WP661566. They should read closed for continuity. Hope this helps.
