Possible Causes

Damaged or dirty silicone gasket, Steam release valve not sealing, Debris on lid rim, Worn float valve seal

How to Fix / Troubleshooting

Safety first: Keep hands and face away from escaping steam. Turn off and release pressure before opening the lid.

  • Inspect and clean gasket: Remove the silicone gasket, wash it thoroughly, and check for cracks or stretching. Replace if worn.
  • Clean lid rim and body rim: Wipe both surfaces to remove food residue or oil that can prevent sealing.
  • Check steam release valve: Ensure the valve is in the Sealing position and that its silicone cap (if present) is intact and flexible.
  • Inspect float valve: Remove and clean the float valve and its silicone seal. Ensure it moves freely and reseats properly.
  • Test with water only: Run a short pressure cycle with water to confirm that the leak is resolved.
