Error Code: ER-09 Difficulty: Moderate
Problem: There is a communication failure between the user interface control and the electronic control board.
How to Fix ER-09 Error (Step-by-Step)
- Reset the dishwasher’s power. Turn off the circuit breaker dedicated to the dishwasher for at least five minutes to allow the internal electronics to fully discharge and reset.
- If the code persists, turn the power off again at the circuit breaker. You will now inspect the wire connection to the user interface in the door.
- Open the dishwasher door and remove the Torx screws holding the inner door panel to the outer panel. Be sure to support the outer panel as you remove the last screws so it doesn’t fall.
- Locate the main wire harness that connects to the user interface control at the top of the door. Carefully disconnect the plastic connector by squeezing its locking tab and pulling gently.
- Inspect the connector and the pins on the board for any signs of corrosion or damage. If it looks clean, firmly plug the connector back in until you hear it click into place, ensuring a secure connection.
- Reassemble the door panels, restore power at the circuit breaker, and run a test cycle to confirm the error is resolved. If the error returns, the main control board or user interface may need professional service.
- Turn the appliance off, wait about 2 minutes, then turn it back on.
