Possible Causes

Incorrect or non-original temperature sensor installed, Sensor value out of calibration range, Control board expecting different sensor type, Loose sensor mounting causing poor thermal contact

How to Fix / Troubleshooting

Safety first: Unplug and cool the cooker before accessing sensors.

  • Confirm original parts: If a sensor was recently replaced, verify that it is an original Lagostina NTC with the correct specification for your model.
  • Check sensor mounting: Ensure the bottom sensor is firmly clamped to the heating plate and the lid sensor is properly seated against the metal surface, not hanging loose.
  • Inspect connectors: Reseat the sensor connectors on the control board to ensure good contact.
  • Factory reset: Perform a factory reset if supported, to clear any stored calibration offsets.

If E18 persists with correct sensors installed, the control board may require replacement or reprogramming.
