How to Fix / Troubleshooting
Safety first: Unplug the cooker before further steps.
- Power reset: Unplug the unit for at least 15 minutes to allow capacitors to discharge, then plug back in and test with a simple program like Saute.
- Check for other codes: Some models show 'Err' followed by a number. Note any additional code and refer to specific troubleshooting.
- Inspect for visible damage: Look for burn marks, melted plastic, or a burnt smell from the base. If present, discontinue use.
- Surge protection: If the error followed a power outage or surge, consider using a surge protector after repair.
- Board replacement: If 'Err' persists with no other code and basic resets fail, the main control board is likely defective and should be replaced by a qualified technician.
