Possible Causes
How to Fix / Troubleshooting
Safety first: Unplug the microwave.
Reset attempts:
- Leave the unit unplugged for at least 10–15 minutes to allow capacitors to discharge and the control to fully reset.
- Plug back in and check if the error clears.
Surge protection:
- If the error occurred after a storm or power cut, consider using a surge-protected outlet for future use.
Next steps: If E18 remains, the control board firmware or memory is likely corrupted. This typically requires control board replacement or reprogramming by an authorized Candy service center.
