Possible Causes
Faulty touch control PCB, Damaged ribbon cable between UI and main board, Moisture ingress behind control panel
How to Fix / Troubleshooting
Safety first: Disconnect mains power before removing the control panel or top cover.
Step-by-step checks:
- Dry the panel: If the error appeared after cleaning or a spill, leave the dryer unplugged for several hours to allow moisture to evaporate.
- Inspect the fascia: Remove the control panel fascia and check for signs of water marks, corrosion, or detergent residue on the PCB.
- Check ribbon cable: Ensure the flat ribbon cable between the user interface board and main control PCB is fully seated and not damaged or kinked.
- Look for cracked solder joints: On the UI board, inspect around buttons and connectors for cracks or lifted pads.
When to call a technician: If cleaning and reseating cables do not resolve E12, the user interface PCB may need replacement.
