How to Fix / Troubleshooting

Safety first: Ensure the cooker is not under pressure.

  • Check lid alignment: Open and close the lid, aligning any arrows or marks as indicated in the manual.
  • Set valve correctly: Turn the steam release knob to the pressure position.
  • Inspect hinge: Look for obstruction or damage at the hinge that prevents full closure.
  • Sensor issue: If the code persists with the lid clearly locked, the lid position sensor may be faulty and require replacement.
