Step 2: Check and Clean the Sealing Ring
Remove the sealing ring from the lid. Inspect it for cracks, deformation, or any signs of wear. If it looks damaged, replace it with a genuine replacement, such as the Instant Pot Sealing Ring (ASIN: B008FUUQJW).
Clean the sealing ring thoroughly with warm, soapy water to remove any food residue or grease that might prevent a proper seal. Dry it completely before reinstalling.
Step 3: Verify the Lid and Pot Contact
Ensure the lid is sitting evenly on the pot. Sometimes, food or debris on the rim can interfere with sealing. Wipe the rim of the inner pot with a clean, damp cloth to remove any residue.
Check that the anti-spin design of the pot remains aligned and that the lid’s locking mechanism engages fully without obstruction.
Step 4: Confirm the Valve and Vent
- Ensure the steam release handle is in the ‘Sealing’ position, not venting or venting partially.
- Open and close the pressure release valve to check for any blockages or debris.
- Clear any obstructions that may prevent the valve from sealing properly.
Step 5: Test the Seal and Pressure
Fill the pot with a small amount of water and secure the lid correctly. Set the cooker to a pressure cooking mode and start it. Watch for the pressure indicator to rise and the steam to begin releasing from the valve.
If it reaches pressure and maintains it without releasing steam prematurely, the seal is now working. If not, revisit the previous steps or consider replacing the sealing ring.
Tips and Warnings
- Use Genuine Parts: Always opt for authentic replacement seals to ensure compatibility and safety.
- Regular Maintenance: Clean the sealing ring and rim after each use to prevent buildup.
- Safety First: Unplug the Instant Pot before inspecting or replacing parts to avoid electrical hazards.
- Replace When Necessary: If the sealing ring is cracked or deformed, replace it promptly for safety and performance.
- Avoid Overfilling: Do not fill the pot beyond the maximum fill line, which can affect sealing and safety.

Yes, a damaged or worn sealing ring can prevent the proper pressure seal, leading to failure in reaching or maintaining pressure.
How often should I replace the sealing ring?
It’s recommended to replace the sealing ring every 12-18 months or sooner if you notice cracks, tears, or persistent odors.
