Inspect and Reinstall the Sealing Ring

  • Remove the sealing ring from the lid and inspect for cracks, tears, or deformation.
  • Clean the ring with warm soapy water and dry thoroughly.
  • Reinstall the ring, making sure it sits snugly in the groove without twists or kinks.

Check the Lid and Gasket Alignment

Ensure the lid is properly aligned and locked into position. The sealing ring should be evenly seated around the lid groove. If misaligned, remove and reposition it carefully.

Clean the Components

  • Wash the lid, sealing ring, and lid groove thoroughly to remove residue or food particles.
  • Use a soft brush or cloth to reach tight spots.
  • Dry all parts completely before reassembling.

Replace the Sealing Ring if Needed

If the sealing ring is damaged or worn out after multiple uses, consider replacing it with a genuine Instant Pot sealing ring for safety and optimal performance.

It’s recommended to replace the sealing ring every 12-18 months or if you notice cracks, tears, or persistent odors that can’t be eliminated through cleaning.

Can I use a different sealing ring?
