Possible Causes
Loose UI harness connection, Damaged ribbon cable, Failed user interface board, Failed main control board
How to Fix / Troubleshooting
Safety First: Turn off power at the circuit breaker.
- Access wiring: Remove the inner door panel screws and carefully separate the console to expose the user interface and wiring.
- Reseat connectors: Disconnect and reconnect the ribbon cable and harness connectors between the UI and main control board. Ensure they are fully seated and locked.
- Inspect for damage: Look for pinched wires, broken insulation, or burn marks on the connectors or boards. Replace any damaged harness.
- Check continuity: If you have a multimeter and skills, test continuity of the ribbon cable from end to end. Replace if open.
- Board replacement: If wiring is good and the error persists, either the UI board or main control board is defective. Whirlpool service manuals often recommend replacing the UI first, then the main control if needed.
