Step 2: Check and Remove the Sealing Ring

  3. Clean the ring with warm, soapy water and dry thoroughly.

Step 3: Ensure Proper Lid Alignment and Closure

  • Position the lid correctly, aligning the markings and locking it into place securely.
  • Make sure the lid is fully closed; it should click or lock into position.

Step 4: Clean the Float Valve and Vent

Remove the float valve and check for any debris or food particles blocking it. Clean gently with a soft brush or cloth. Confirm the vent is clear and unobstructed.

Step 5: Test the Seal

Reassemble the lid with a fresh or cleaned sealing ring, close it securely, and try to build pressure. If it still doesn’t seal, check the lid gasket seating and the condition of the lid itself.
