How to Fix / Troubleshooting
Safety first: Unplug the cooker before troubleshooting.
- Hard reset: Unplug the unit for at least 10 minutes, then plug back in. This can clear temporary logic faults.
- Avoid rapid mode changes: Allow the cooker to stop and cool slightly between very different modes (e.g., from Sauté to Pressure) to reduce stress on electronics.
- Check environment: Ensure adequate ventilation around the cooker to prevent internal overheating.
- Persistent E18: If the error recurs frequently, the control board firmware or MCU is likely damaged. There is no user-accessible firmware update for most GreenPan models.
- Repair: Replace the main control board through an authorized service provider.
