Properly Close the Lid

  • Align the lid correctly on the base, making sure it sits flush.
  • Turn the lid clockwise until it locks securely.
  • Confirm the steam release handle is in the ‘Sealing’ position.

Clean and Check for Debris

Food residue, dried liquids, or debris can prevent a tight seal. Remove the sealing ring and wash it thoroughly with warm, soapy water. Also, inspect the lid’s groove and the edge of the pot for any food particles or buildup that might interfere with sealing.

Test the Seal

  1. Fill the inner pot with 2 cups of water.
  2. Secure the lid properly and set the cooking mode to ‘Pressure Cook’.
  3. Start the cooker and observe if it reaches pressure within 10 minutes.
  4. If it does, the seal is likely functioning correctly; if not, revisit the above steps.

Additional Tips & Warnings

  • Always use genuine replacement parts for safety and compatibility.
  • Never force the lid closed if it doesn’t lock easily; check for obstructions.
  • A damaged or deformed lid or sealing ring may require professional repair or replacement.
