Possible Causes
Failed backup capacitor on control board, Faulty clock IC, Voltage drop due to weak mains connection, Internal control board fault
How to Fix / Troubleshooting
Safety first: Turn off power before accessing the control board.
Checks:
- Verify mains stability: Ensure the oven is on a dedicated circuit and that the cooker switch and wiring are in good condition.
- Inspect control board: Remove the control panel and inspect the PCB for bulging electrolytic capacitors or burn marks.
- Reseat connectors: Loose low-voltage connectors can cause resets. Reseat all plugs on the control board.
- Replace board: If E12 persists and capacitors appear damaged, replace the electronic control board. Component-level repair is possible but not recommended for non-professionals.
Note: Frequent power cuts can also cause clock resets without a fault; use a surge protector if your supply is unstable.
