How to Fix / Troubleshooting

Safety first: Avoid leaving food unattended on Keep Warm until the issue is resolved.

  • Stir and add liquid: Stir food before switching to Keep Warm and ensure there is sufficient liquid to prevent sticking.
  • Clean heating plate and sensor area: Remove the inner pot and clean the plate thoroughly. Any residue can cause hot spots and misreadings.
  • Test with water: Fill the pot with water and run Keep Warm. Measure the water temperature after 30–60 minutes; it should be hot but not boiling. Boiling indicates a regulation fault.
  • Inspect sensor: If overheating persists, check the bottom NTC sensor and wiring for damage or poor contact.

Persistent overheating on Keep Warm usually requires sensor or PCB replacement by a technician.
