Inspect and Clean the Sealing Ring

  • Remove the sealing ring from the lid and examine it for cracks, tears, or deformation.
  • Wash the ring with warm, soapy water and dry thoroughly.
  • Reinstall the ring ensuring it sits flat and snug within the lid groove.

Check for Obstructions or Debris

Look around the rim of the lid and the sealing ring groove for any food particles, residue, or debris that could prevent a proper seal. Clean these areas carefully with a soft cloth or brush.

Test the Seal and Perform a Water Test

  1. Fill the inner pot with 1-2 cups of water.
  2. Close and lock the lid securely, ensuring the sealing ring is in place.
  3. Set the Instant Pot to ‘Pressure Cook’ for 2-3 minutes.
  4. Observe if the unit reaches pressure and seals properly; if it does, the issue was likely debris or misalignment.

Replace the Sealing Ring if Necessary

If the sealing ring is damaged, cracked, or no longer pliable, replace it with an authentic Instant Pot Sealing Ring for 5 & 6-Qt models. This is a common fix for persistent sealing issues.
