KitchenAid Dishwasher Error Code F2E2 — User Interface Communication Failure
What this means
The F2E2 error code on KitchenAid dishwashers indicates a communication failure between the user interface control panel and the main electronic control board. The two boards cannot exchange data, so the dishwasher cannot accept commands or display status. This is typically caused by a loose wiring harness, a failed interface board, or a failed main board.
Alternate codes: 2-2
Step-by-step fix
3 stepsReset the dishwasher
Unplug the dishwasher for 5 minutes, then restore power. Communication errors can sometimes be caused by a temporary glitch.
Check the wiring harness
Unplug the dishwasher. Open the door panel to access the wiring between the user interface and the main control board. Ensure all connectors are fully seated and check for damaged or pinched wires.
A loose ribbon cable or connector is the most common cause of F2E2.
Replace the user interface board
If the wiring is intact, replace the user interface control board first, as it's less expensive than the main board. If the code persists, replace the main electronic control board.
When to call a professional
If replacing the interface board doesn't fix the issue, both boards may need diagnosis. A technician can test which component has failed.
