Possible Causes
How to Fix / Troubleshooting
Safety first: Unplug the cooker before removing the control panel. Glass edges can be sharp if cracked.
Steps to resolve:
- Check for impact damage: Inspect the front display for cracks or signs of impact. If the glass is broken, the display module must be replaced.
- Reseat connectors: Remove the control panel and reseat the ribbon cable between the display and the main or interface PCB.
- Inspect for corrosion: Look for signs of liquid ingress around the display connector. Clean gently with isopropyl alcohol and a soft brush if needed.
- Test operation: Reassemble and power on to see if the display is stable.
When to call a technician: If E20 persists or the display remains unstable, replacement of the display module or control board is required and should be done professionally.
