Possible Causes
Failed optical rinse aid sensor in dispenser, Disconnected dispenser wiring, Control board not reading sensor correctly, Use of incompatible rinse aid
How to Fix / Troubleshooting
Safety first: Disconnect power before removing the inner door panel.
- Verify rinse aid level: Confirm the dispenser is actually full and that the cap is sealing properly.
- Inspect dispenser wiring: Remove the inner door panel and check the connector to the dispenser assembly for a secure fit.
- Replace dispenser assembly: If wiring is intact and the code persists, replace the entire dispenser assembly, which includes the rinse aid sensor.
- Control board check: If a new dispenser does not clear the code, the main control board may be misreading the sensor and require replacement.
