Ensure the Lid is Properly Locked

Align the lid correctly with the base. Turn the lid clockwise until it clicks and locks into place. The lid must be fully seated and aligned for a proper seal.

Inspect the Sealing Ring for Debris or Damage

  • Look for food residue, grease, or debris on the sealing ring and lid groove.
  • Clean the ring and groove with warm soapy water if needed.
  • Replace the sealing ring if it shows signs of cracking or wear.

Check the Lid and Valve for Proper Closure

Ensure the steam release valve is set to sealing position and not venting. Confirm the lid is fully closed and the anti-spin feature is engaged, keeping the pot steady during sealing.

Additional Troubleshooting Tips

  • Try resetting the Instant Pot by unplugging it for a few minutes, then plugging back in.
  • Make sure the float valve is clean and moves freely; a stuck float can prevent sealing.
  • If the problem persists, consider replacing the sealing ring with a new one, such as the Instant Pot Sealing Ring 5 & 6-Qt.
