Check and Replace the Sealing Ring
- Open the lid and remove the sealing ring from the lid assembly. Check for cracks, tears, or deformations. If the ring appears damaged, replace it with a new one designed for your model (e.g., the Instant Pot Sealing Ring 5 & 6-Qt).
- Ensure the sealing ring sits properly in its groove. It should be snug and evenly positioned around the lid.
- For best results, wash the sealing ring with warm soapy water and dry thoroughly before reinstalling. A clean, flexible ring creates a better seal.

Verify the Lid and Locking Mechanism
- Close the lid firmly, aligning it correctly with the markings. Ensure the lid is properly locked into place; you should hear a click when it’s securely engaged.
- Check that the anti-spin design is properly aligned to prevent the lid from moving during pressure buildup.
- If the lid doesn’t lock or feels loose, inspect the locking mechanism for damage or obstruction.
Inspect the Float Valve and Steam Release
The float valve plays a critical role in sealing. When the lid is locked, the float valve should be in the upward position, indicating a proper seal. If it sticks down or is blocked, pressure cannot build up.
- Remove the lid and clean the float valve and steam release with a soft brush or cloth to remove any debris or food residue.
- Ensure the float valve moves freely and returns to the upward position when reassembled.
Clean and Maintain the Lid and Gasket Area
Build-up of food, grease, or mineral deposits can impair sealing. Regular cleaning of the lid, gasket groove, and surrounding areas helps maintain optimal sealing conditions.
- Use a damp cloth or soft brush to clean the lid’s groove and around the sealing ring.
- Check for any stuck debris or residue that could prevent a tight seal.
- Avoid using abrasive cleaners that could damage the silicone gasket or lid surface.
Test and Confirm Proper Sealing
- After performing the above checks, add a small amount of water to the inner pot and close the lid securely.
- Set your Instant Pot to the pressure cooking mode and observe if the lid seals and the pressure indicator rises accordingly.
- If it still won’t seal, repeat the previous checks or consider replacing parts.
