Check the Sealing Ring
- Unplug your Instant Pot and remove the lid.
- Take out the sealing ring from the lid. Inspect it for cracks, tears, or deformations. A worn or damaged ring won’t seal properly.
- If the ring looks damaged, replace it with a new one. Consider the silicone sealing ring for 5/6 quart models, which is dishwasher safe and easy to clean.
- Ensure the ring is seated correctly in the lid’s groove. It should sit flush without any twists or gaps.

Verify the Lid Placement and Locking
- Align the lid correctly on the base, ensuring the arrows or markings are matched.
- Turn the lid clockwise or according to your model’s instructions until it clicks into place. The lid must be securely locked to create a proper seal.
- Check the rubber gasket around the lid for any misalignment or debris, which can prevent sealing.
Set and Check the Steam Release Handle
Ensure that the steam release handle or valve is in the ‘Sealing’ position. If it’s turned to ‘Venting’ or left loose, the cooker cannot build pressure or seal properly. Confirm it’s fully engaged in the sealing position before starting your cooking cycle.
Clean and Inspect the Float Valve and Vent
- Remove the lid and check the float valve, which is a small metal pin or post. It must move freely and be clean of any food debris or residue. A stuck float valve can prevent the lid from sealing.
- Similarly, inspect the steam vent and sealing ring for any obstructions or residue that might prevent a tight seal. Clean with a soft brush or cloth as needed.
Test the Sealing Function
- After cleaning and reassembling all parts, add a small amount of water (about 1 cup) into the inner pot.
- Secure the lid properly and set the steam release handle to ‘Sealing’.
- Press the ‘Steam’ or ‘Manual’ button and see if the cooker builds pressure and the pin or float rises. If it does, your seal is working.
- If not, repeat the above steps or consider replacing the sealing ring or lid if issues persist.
