Possible Causes
Faulty clock module on control board, Power supply instability to control PCB, Corrupted EEPROM on main PCB, Loose ribbon cable to display board
How to Fix / Troubleshooting
Safety first: Switch off power before accessing the control area.
Steps to check:
- Remove the control panel fascia to access the display/clock board and its ribbon cable.
- Reseat the ribbon cable and connectors between the display and main PCB.
- Inspect the PCB for signs of moisture or corrosion; clean with appropriate electronics cleaner.
- Verify that the mains supply to the oven is stable and that the terminal block connections are tight.
- If E12 persists and the clock loses time or settings, replace the control panel module or the main PCB depending on model design (some Gram ovens integrate the clock into the main board).
Warning: Do not spray cleaners directly onto the control panel; liquid ingress can damage electronics.
