Customer Questions and Answers for Dishwasher Electronic Control Board by Whirlpool

Hi Don. Remove the drain hose indside the sink along withe a bucket to see if the hose is clogged or the sink connection is clogged. Use a screwdriver inside the sink pipe is clogged. Remove the drain hose at the pump to see if the pump is clogged. Make sure the impeller is not spinning loose on the motor shaft. If the chopper blade is clogged and the sump filter is clogged, then it will not drain properly. There is a optical water sensor that shoots infra red between 2 prisms to see if the water is dirty or clean. It also has a thermistor which reads the water temperature. So complete drain and inner clean ability are sensed to work properly. Inside the inner door by the control panel or in the back of the toe kick panel is a supplied tech. sheet. It allows you to put the unit in a diagnostic mode which brings up fault codes and tells you which circuit needs assistance. If the start is flashing then the door latch part # WPW10404409 contacts are not closing. Thank You.
