Lid Seal / Gasket Failure
Multicooker heats but never reaches pressure; steam constantly escapes from the lid area.

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.
