How to Fix / Troubleshooting

Safety: Steam can cause burns. Always keep hands away from the steam path.

Step 1 – Inspect sealing ring:

  • Remove and clean the silicone sealing ring and its groove.
  • Check for cracks, cuts, or permanent deformation; replace if any damage is found.

Step 2 – Clean lid surfaces:

  • Wipe the metal or plastic sealing surface on the lid and the top edge of the inner pot.
  • Remove any food residue or dried starch.

Step 3 – Check valves:

  • Ensure the steam release valve is in the sealing position.
  • Inspect the float valve gasket and replace if hardened or cracked.

Step 4 – Test:

  • Run a water-only pressure test to confirm that pressure now builds and steam leakage has stopped.
