How to Fix / Troubleshooting
Safety first: Unplug the washer before removing the console.
- Access control console: Remove screws securing the top or front console and gently pull it forward.
- Reseat UI connectors: Disconnect and reconnect the ribbon cable or harness between the user interface and main control. Ensure a snug fit.
- Inspect for damage: Look for corrosion, burnt spots, or cracked solder joints on the UI board and main control.
- Replace faulty board: If reseating does not resolve E91, replace the user interface board first. If the error persists, replace the main control board.
- Test controls: Reassemble and verify that all buttons and display functions work and that E91 is cleared.
