Possible Causes

Worn or damaged silicone lid gasket, Gasket installed upside down or twisted, Debris on lid sealing surface, Warped lid or inner pot rim

How to Fix / Troubleshooting

Safety first: Keep hands and face away from escaping steam. Turn off and unplug the cooker before detailed inspection.

  • Inspect gasket: Remove the silicone gasket from the lid. Look for cracks, flattening, or hard spots. Replace if any damage is found.
  • Clean sealing surfaces: Thoroughly clean the gasket groove, lid sealing ring, and the top rim of the inner pot. Dry completely.
  • Reinstall correctly: Fit the gasket evenly into the groove, ensuring it is not twisted and is fully seated all around.
  • Check inner pot rim: Inspect the rim for dents or warping. Replace the pot if the rim is not perfectly round and smooth.
  • Test with water: Run a short pressure cycle with water only to confirm that steam no longer leaks around the lid.
