Problem: No error code stored – communication failure between control boards preventing code retrieval
How to Fix Washer Error
- Unplug washer for 10 minutes to fully reset all control boards.
- Remove top panel to access main control board (CCU) connections.
- Disconnect and reconnect all wire harnesses at CCU, especially serial communication cables.
- Inspect harness routing for pinch points between cabinet panels or near moving components.
- Check for moisture damage or corrosion on board connectors – clean with electrical contact cleaner if needed.
- Verify 120V AC power supply to CCU is stable (no voltage sags during operation).
- Enter diagnostic mode per model-specific procedure to force error code display.
- If F0E0 persists after harness reseating, suspect corrupted EEPROM on CCU.
- Replace main control board assembly W
- After replacement, run full diagnostic cycle and document any new error codes that appear for further troubleshooting.
