Possible Causes
Loose or damaged ribbon cable between UI and main PCB, Faulty user interface (control panel) board, Moisture intrusion into control panel, Main control board communication failure
How to Fix / Troubleshooting
Safety first: Unplug the washer before opening the control console.
- Dry the panel: If the control panel was exposed to steam or splashes, allow it to dry completely for several hours, then retry.
- Inspect connections: Remove the control console cover and locate the ribbon cable or harness between the user interface and main board. Reseat both ends firmly.
- Check for corrosion: Look for green or white corrosion on connectors. Clean lightly with contact cleaner and a soft brush if present.
- Test operation: Reassemble and plug in the Insignia washer. If E12 persists, the UI board or main board may be defective.
- Replace UI board: Start by replacing the user interface/control panel board, as it is often the source of communication errors. Match the Insignia part number exactly.
- Main board replacement: If a new UI does not resolve E12, the main control board likely needs replacement by a professional.
