Check the Sealing Ring for Damage or Misplacement
- Remove the lid from your Instant Pot and carefully take out the sealing ring. The sealing ring is usually made of silicone and sits in the lid’s groove.
- Inspect it closely for cracks, tears, or deformations. If the ring appears damaged, it will need replacing.
- Ensure the ring is seated properly in the lid’s groove, with no twists or misalignments. A misaligned ring can cause leaks and prevent sealing.
- For best results, clean the ring with warm, soapy water and dry thoroughly before reinserting.

Verify Proper Lid Placement and Locking
Always ensure the lid is aligned correctly with the body of your Instant Pot. The lid should sit flush and lock securely into place. Many models have a locking mechanism that clicks when properly closed.
Double-check that the sealing ring is inside the lid, and the lid’s handle is aligned with the markings or indicators. If the lid is not securely locked, pressure will not build, and the unit may display a not-sealing error.
Inspect and Clean the Steam Release Valve and Float Valve
- Remove the steam release handle or valve (if removable) and clean it thoroughly with warm water. Debris or dried food can block the vent, preventing the lid from sealing properly.
- Check the float valve (the small metal or plastic pin that pops up when under pressure). If it’s stuck or dirty, press it gently to ensure it moves freely and is not obstructed.
- Clean all components with a soft brush or cloth to clear any buildup that might interfere with sealing.
Test the Lid and Components for Proper Functionality
After cleaning and inspecting, reassemble your Instant Pot and try a test run with water. Close the lid securely, set to pressure cook, and observe whether the unit reaches pressure and maintains a seal.
If it still doesn’t seal, try replacing the sealing ring with a new one, such as the compatible silicone sealing ring for 5/6-quart models. Proper maintenance and timely replacements are key to consistent sealing performance.
Additional Tips and Warnings
- Always use genuine replacement parts like the Instant Pot Sealing Ring (ASIN B008FUUQJW) or silicone rings designed for your model.
- Never force the lid shut or lock it if it doesn’t close easily. Forcing can damage the locking mechanism or gasket.
- Regularly inspect and replace the sealing ring every 12-18 months or sooner if it shows signs of wear.
- Avoid using abrasive cleaners or sharp tools on silicone parts to prevent damage.
- Ensure your model’s vent and float valve are free of debris before each use for optimal sealing.
