Step 2: Verify Lid Alignment and Locking
- Place the lid on the cooker, aligning the arrows or marks as indicated in your manual.
- Ensure the lid locks securely into place; a loose lid can prevent sealing.

- Remove the pressure release valve and float valve from the lid (if removable).
- Wash them thoroughly with warm, soapy water and dry completely.
- Check for blockages or debris that could prevent the valves from functioning properly.
Step 4: Test the Lid and Valve Assembly
After reassembling, fill the pot with a small amount of water and set it to pressure cook. Observe if the lid seals and the pressure builds as expected. If not, repeat the inspection and cleaning process or consider replacing the sealing ring.
