Possible Causes

Aging NTC sensors, Incorrect inner pot type or thickness, Firmware calibration drift, Poor contact between pot and heater

How to Fix / Troubleshooting

Safety first: Unplug and cool the cooker before internal checks.

  • Use original pot: Confirm you are using the original AEG inner pot. Non-original pots can alter heating characteristics.
  • Clean contact surfaces: Remove any burnt-on residue from the heating plate and pot bottom.
  • Compare with manual: Verify that you are using the correct program and liquid ratios as per the AEG recipe guide.
  • Sensor check: If you have a multimeter, test the main NTC sensor resistance at room temperature. Replace if significantly off-spec.
  • Service calibration: Persistent calibration issues may require firmware update or PCB replacement by an authorized AEG service center.
