Possible Causes
Corrupted firmware, failed memory chip on PCB, unstable power supply to control board, PCB track damage
How to Fix / Troubleshooting
Safety first: Disconnect the oven from mains before removing the control board.
- Power reset: Turn off power for 15 minutes to fully discharge the electronics, then restore. If E020 returns, a hardware fault is likely.
- Check for surges: If the error appeared after a power surge or outage, consider using a surge protector for the oven circuit (if permitted by local regulations).
- Inspect PCB: Remove the control board and inspect for burnt components, cracked solder joints, or moisture damage.
EEPROM or firmware faults generally require replacement of the main control board. Reprogramming is not typically available to end users.
