Ensure Proper Lid Placement

  1. Align the lid correctly, ensuring the arrow aligns with the lock indicator.
  2. Press down firmly until you hear a click or feel the lid securely in place.
  3. Check that the sealing ring is not pinched or displaced during closure.

Clean and Replace Components

  • Wash the sealing ring with warm, soapy water and dry thoroughly.
  • If the ring is cracked or deformed, replace it with a genuine Instant Pot sealing ring.
  • Consider replacing the sealing ring every 12-18 months for optimal sealing.

Test the Seal

After reassembling, close the lid securely and turn the steam release handle to the sealing position. Check for any steam escaping around the edges. If steam escapes, double-check the ring placement or replace it.

Additional Tips & Safety Warnings

  • Always use authentic replacement parts for safety and compatibility.
  • Avoid forcing the lid closed, as this can damage the lid or sealing ring.
  • Ensure the bottom of the lid is clean and free of food debris.
  • Never operate the Instant Pot if it’s not sealing properly, as it can be a safety hazard.
