How to Fix / Troubleshooting
Safety first: Avoid leaving the cooker unattended on Keep Warm for many hours until the issue is resolved.
- Limit keep warm time: Manually turn off Keep Warm after 1–2 hours and store food safely.
- Stir and add liquid: Stir food before activating Keep Warm and add a small amount of liquid to prevent drying.
- Check inner pot: Ensure the pot is not warped and that the bottom is clean for even heating.
- Test with water: Run Keep Warm with only water and measure the temperature with a food thermometer. If it is significantly above typical holding temperatures (around 60–75°C), the sensor or PCB may be faulty.
Persistent overheating on Keep Warm suggests a control issue; contact a service center for sensor or PCB evaluation.
