Possible Causes

Worn or stretched silicone sealing ring, Food residue on lid or pot rim preventing seal, Lid not fully locked, Damaged or warped lid

How to Fix / Troubleshooting

Safety first: Do not place your face or hands directly over escaping steam. Turn off and allow pressure to release before opening.

Steps:

  • After depressurizing and cooling, remove the silicone sealing ring from the lid. Wash it and the lid groove with warm soapy water, then dry thoroughly.
  • Clean the top rim of the inner pot where the seal contacts, removing any dried food or oil.
  • Inspect the sealing ring for cracks, flattening, or hard spots. Replace if any damage is found or if it no longer fits snugly.
  • Reinstall the ring evenly in the lid groove, ensuring it is not twisted.
  • Perform a water-only pressure test. If steam still leaks around the lid, inspect the lid for warping or damage and consider replacing the lid assembly.
