KitchenAid Dishwasher Error Code F1E1 — Control Board (ACU) Failure
What this means
The F1E1 error code on KitchenAid dishwashers indicates a stuck relay on the electronic control board (ACU — Appliance Control Unit). The relay is an electrical switch on the board that controls major components like the wash pump or heating element. When a relay gets stuck, the board cannot properly control the dishwasher's functions.
Alternate codes: 1-1
Step-by-step fix
3 stepsReset the dishwasher
Unplug the dishwasher or turn off the circuit breaker for 5 minutes. Restore power and run a cycle. A temporary electrical glitch can sometimes cause a false F1E1.
If the code clears after a reset and doesn't return, no further action is needed.
Check wiring connections
If the code returns, unplug the dishwasher and access the control board (usually behind the door panel). Check all wire connectors on the board for loose, burned, or corroded connections.
Look for any signs of heat damage or melted plastic around the relay area on the board.
Replace the control board
If the relay is stuck, the electronic control board must be replaced. Photograph all wire connections, disconnect them, remove the old board, install the new one, and reconnect all wires.
Match the part number to your specific model — KitchenAid uses different boards for different dishwasher series.
