Step 1: Ensure the Sealing Ring Is Properly Installed
- Remove the lid and take out the sealing ring from the lid.

Step 2: Check the Lid Placement and Locking Mechanism
- Align the lid properly on the Instant Pot, making sure the arrows or markings match.
- Turn the lid clockwise until it clicks into place, ensuring it is fully locked.
- Confirm the steam release handle is set to the sealing position.
Step 3: Clean the Sealing Surface and Lid Gasket
- Wipe the sealing surface on the lid and the rim of the inner pot with a damp cloth.
- Remove any food residue, grease, or debris that may prevent a good seal.
