Inspection TipsCheck for damage, debris, or improper placement of parts.
Step-by-Step FixesFollow clear instructions to resolve sealing problems quickly.
Safety FirstAlways ensure the lid and parts are properly aligned before cooking.

Check the Seal Ring

  1. Remove the lid and carefully inspect the sealing ring for cracks, tears, or deformations.
  2. Ensure the ring is clean and free of food residue or debris.
  3. Replace the seal ring if damaged or worn out, ideally with an authentic Instant Pot sealing ring for 5 & 6-quart models.

Ensure Proper Lid Placement

  • Align the lid correctly with the sealing ring seat and turn it clockwise until it clicks securely.
  • Make sure the float valve is in the ‘sealing’ position and not stuck or obstructed.

Check the Pressure Release Valve

  1. Remove and clean the pressure release valve and silicone gasket thoroughly.
  2. Ensure the valve moves freely and is correctly seated in its position.
  3. Replace if damaged or malfunctioning.

Test the Lid and Valve Assembly

After cleaning and reassembling, run a quick test without food to see if the cooker seals properly. If it still doesn’t seal, check for any misalignment or damage.

Additional Troubleshooting Tips

  • Ensure the inner pot is correctly positioned and clean.
  • Avoid overfilling the cooker, as excess food can interfere with sealing.
  • If using accessories like a steamer basket, remove them during sealing tests.
