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.
