Possible Causes

Shorted NTC temperature sensor, Sensor detached from heating plate, Stuck triac or relay causing continuous heating, Firmware calibration error

How to Fix / Troubleshooting

Safety first: Unplug the cooker and allow it to cool completely before further use.

  • Check cooking settings: Confirm you are using the correct mode (e.g., "Slow Cook Low" vs "Sear").
  • Inspect inner pot: Ensure the pot bottom is not warped and that the non-stick coating is intact; damaged surfaces can cause hot spots.
  • Clean sensor and plate: Wipe the heating plate and central sensor to remove any burnt residue that may affect temperature sensing.
  • Test with water only: Run a low-temperature program with only water. If it rapidly boils or overheats, the control system is faulty and requires professional repair.
