Kitchenaid Dishwasher Error Codes

Kitchenaid Dishwasher Error Code 3-3 or F3E3

Disconnect the dishwasher drain hose connection from the air gap or the garbage disposal if you have no air gap. Pour water through the drain hose to see if water backs up into the dishwasher tub. If so, replace the portion of the drain hose that connects to the drain pump because the check valve in that hose failed. If water doesn’t back up into the dishwasher through the drain hose, reconnect the hose and run the Service Diagnostics Test according to the instructions in the tech sheet. You should see low soil level indicated during the OWI test in the diagnostic mode. If you see high soil level during the OWI test, unplug the dishwasher and clean the OWI sensor. Reassemble the dishwasher and plug the dishwasher back in to restore electrical power. Run the diagnostic test cycle so the electronic control board will calibrate the OWI sensor on the next cycle. Run a normal wash cycle. If you still see the error code, replace the thermistor/OWI sensor.
