Possible Causes
Loose harness between UI and main board, Failed user interface board, Failed main control board, Corroded connectors
How to Fix / Troubleshooting
Safety first: Unplug the washer before removing the control console.
- Check harness connections: Remove the console and verify the multi-pin connectors between the display/UI board and the main control are fully seated.
- Inspect for corrosion: Look for green/white corrosion or moisture on connectors. Clean lightly with contact cleaner if present (power disconnected).
- Visual board check: Examine both boards for burnt components or cracked solder joints.
- Component replacement: If connections are good and E90 persists, either the UI board or main control board may be defective. Many technicians replace the UI first, then the main board if needed.
