Inspect and Replace the Sealing Ring
- Remove the lid of your Instant Pot carefully, following the manufacturer’s instructions.
- Locate the sealing ring inside the lid; it’s a silicone gasket that creates the pressure seal.
- Check for cracks, tears, or deformations in the ring. If damaged, replace it with an authentic replacement, like the Instant Pot Sealing Ring 5 & 6-Qt.
- To replace, remove the old ring and fit the new one securely into the groove, making sure it sits evenly without twists.
- Reattach the lid and test if the seal improves during your next cooking cycle.

Ensure Proper Lid Placement and Locking
- Align the lid correctly with the base, ensuring the arrow marks or indicators match up.
- Press down firmly and turn the lid clockwise until it locks into place, listening for the locking sound.
- Double-check that the steam release handle is in the ‘Sealing’ position, not ‘Venting.’
- Sometimes, misalignment or an incomplete lock can prevent sealing. Confirm that the lid is fully engaged before starting a pressure cycle.
Clean the Sealing Area and Valve
Debris, food residue, or mineral build-up can interfere with the seal. Remove the lid and thoroughly clean the sealing ring, the silicone gasket, and the steam release valve. Use warm, soapy water and a soft brush to remove any stuck particles. Rinse well and dry completely. Reassemble and test again.
Check for Proper Lid Fit and Internal Components
Inspect the lid for warping or damage, especially around the locking mechanism. Ensure the internal components, like the anti-spin design and steam release valve, are positioned correctly. A warped lid or damaged parts can prevent a proper seal and should be replaced if necessary.
Test the Fix and Troubleshoot Further
After performing the above steps, run a quick test cycle with just water. Seal the lid, select a short cooking time, and observe if the device builds pressure properly. If it still doesn’t seal, consider replacing the sealing ring or consulting customer support for further assistance.
