Error Code: E91 Difficulty: Hard
Problem: User interface board or UI/main board communication failure.
How to Fix E91 Error (Step-by-Step)
- Power down the washer completely by unplugging it from the wall outlet.
- Access both the main control board (usually at the bottom or back) and the user interface board (in the top console).
- Carefully inspect the wiring harness that runs between the two boards.
- Look for any signs of pinched, broken, or disconnected wires.
- Reseat the connections on both ends of the harness to ensure a firm connection.
- If the wiring looks good, the issue is likely one of the boards. Replacing the user interface board is often easier for homeowners.
- If replacing the UI board doesn’t solve the issue, the main control board will likely need to be replaced.
- Turn the appliance off, wait about 2 minutes, then turn it back on.
