Possible Causes
Worn or cracked silicone sealing ring, Gasket not seated properly, Debris on lid sealing surface, Damaged lid rim
How to Fix / Troubleshooting
Safety first: Do not touch escaping steam. Turn off and allow pressure to drop naturally before opening.
- Inspect sealing ring: Remove the silicone ring from the lid. Check for cracks, hard spots, or deformation. Replace if any damage is found.
- Clean sealing surfaces: Wipe the lid groove and the top rim of the cooker body to remove food residue.
- Reinstall gasket correctly: Ensure the ring is fully and evenly seated in its groove without twists.
- Test with water: Run a short pressure cycle with only water to confirm the leak is resolved.
