Customer Questions and Answers for Dishwasher Electronic Control Board by Whirlpool

Gary, With the clean light flashing 7 times then pausing then you would have a issue with the heating circuit. If the light just continues to flash without a pause would be a control panel problem. The heating circuit issue you will want to check at the main control board when the unit is on and when the heater is supposed to be on to see if there is 120 vac going to the heater. If there is not then replace the control board. If not then test the heater and thermostat.
