How to Fix / Troubleshooting
Safety first: Unplug the unit before removing the control panel.
- Dry the display area: If condensation is visible under the display window, leave the cooker unplugged in a dry, warm room for 24 hours.
- Inspect display connector: Remove the control panel cover and locate the small connector or ribbon cable going to the LCD/LED display. Reseat it carefully.
- Check for cracks: Examine the display glass or plastic for cracks or impact damage. A cracked module must be replaced.
- Test operation: Reassemble and power on. If E12 persists and the display remains unstable, the display module or driver circuitry is defective.
Replacing the display often requires replacing the entire control panel or main board assembly, depending on model design.
