When the dishwasher stopped working I took apart the door to access the electronics module. I discovered that there was a hole burned thru the circuit board where the tan wire (Line) connection P8 occurs. I thought that the heater element assembly was drawing too much current, however the heating element measured within spec (13.7 ohms) and I tested the thermostat which opened when heated up and closed when cooled down.
Since the tan wire comes from the door switch and there was no sign of the switch taking in too much current, I suspected that the spade connector to P8 was bad causing arching that resulted in a hole in the circuit board.
After replacing the circuit board and splicing in a new spade connector for the P8 connection, my dishwasher is back in business.
Are there any notices/recalls for my Kitchenaid dishwasher?
