Ensure the Sealing Ring Is Properly Installed and Intact
- Remove the lid and take out the sealing ring from the lid’s groove.
- Inspect the ring for cracks, tears, or deformation. If damaged, replace it with a new one.
- Place the sealing ring firmly back into the lid groove, ensuring it sits evenly without twists or pinches.
- Reattach the lid, making sure it aligns properly with the base.
- Double-check that the ring is seated correctly before closing the lid.
A damaged or misaligned sealing ring is a common cause of sealing failure, so regular inspection and replacement are vital for safe operation.

Clean All Components Thoroughly
Residual food, grease, or debris can prevent the lid from sealing correctly. Carefully clean the sealing ring, lid, and the pressure release valve.
- Remove the sealing ring and wash it in warm, soapy water. Rinse thoroughly and dry completely.
- Clean the lid, paying special attention to the silicone sealing ring groove, the steam release valve, and the float valve. Use a soft brush if necessary.
- Ensure the steam release handle is in the ‘Sealing’ position.
- Inspect the lid gasket and the float valve for any blockages or damage.
Regular cleaning prevents buildup that can interfere with sealing and ensures safe pressure cooking.
Check the Lid Alignment and Steam Release Handle
- Place the lid onto the pot, aligning the tabs or marks indicated by your model’s instructions.
- Turn or lock the lid into place, ensuring it is securely fitted.
- Verify the steam release handle is set to the ‘Sealing’ position. If it is in ‘Venting,’ the cooker will not seal.
- Ensure the float valve is clean and can move freely. It should pop up when pressure builds.
- Test by manually pressing the float valve to ensure it moves smoothly and isn’t stuck.
Proper lid placement and correct handle positioning are crucial for achieving a proper seal and safe operation.
Inspect and Replace Worn or Damaged Parts
If the sealing ring appears cracked, deformed, or excessively worn, it’s time for a replacement. Using a worn gasket can prevent the cooker from sealing properly and compromise safety.
Use a compatible replacement like the Instant Pot Sealing Ring 5 & 6-Qt or a food-grade silicone gasket designed for your model.
Install the new sealing ring carefully, ensuring it seats evenly. Avoid stretching or twisting it during installation.
Always keep spare sealing rings handy for quick replacement when needed.
Check other components such as the lid gasket, steam valve, and float valve periodically for wear and tear.
Replacing worn parts maintains the safety, performance, and longevity of your Instant Pot.
Test the Seal and Final Checks
Once you’ve inspected and cleaned or replaced parts, perform a test run.
- Fill the pot with 1 cup of water and secure the lid properly.
- Set the steam release handle to ‘Sealing.’
- Select a quick pressure cook setting and start the cycle.
- Monitor the display for the ‘Sealing’ indicator. If it seals properly, the float valve should rise within a few minutes.
- If it doesn’t seal, recheck all components, especially the sealing ring placement and lid alignment.
Repeat this process until the cooker seals reliably. Always follow safety procedures during testing.
