Ensure the Lid is Properly Seated
Sometimes, an improperly aligned lid prevents sealing. Make sure the lid is aligned with the body and securely locked into position. The lid should turn easily and click when in the sealed position.
Check the Float Valve and Steam Release
- Ensure the float valve is clean and free of debris. It should move freely and sit flush when sealed.
- Make sure the steam release handle is set to ‘Sealing’ and not ‘Venting.’
Clean and Replace Parts as Needed
Dirty or worn sealing rings and float valves can cause sealing issues. Clean all parts thoroughly with warm soapy water and replace worn parts like the sealing ring or float valve if necessary.
Perform a Test Run
After completing the above steps, run a short pressure cycle with water to test if the pot seals properly. If it still doesn’t seal, recheck the lid and parts or consider replacing the sealing ring.
