Step 2: Check and Remove the Sealing Ring
- Open the lid carefully and remove the sealing ring from the lid.
- Inspect the ring for cracks, tears, or deformation. If damaged, replace it with a new one.
- 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.
