Possible Causes

Pressure not fully released, Starch residue acting as glue on gasket, Warped lid or pan rim, Faulty pressure release path

How to Fix / Troubleshooting

Safety first: Never force open a lid that may still be under pressure. Keep face and hands away from vent.

  • Wait longer: Allow additional time for natural pressure release and cooling.
  • Check pressure indicator: On pressure models, ensure the indicator has dropped before attempting to open.
  • Gently break seal: Once safe, press the lid release button or lever firmly. If still stuck, unplug and allow to cool completely before trying again.
  • Clean gasket and rim: After opening, clean the gasket and pan rim thoroughly to remove sticky residue.

When to call a technician: If the lid repeatedly sticks or the pressure release mechanism seems blocked, professional service is required.
