Inspect and Replace the Sealing Ring
Remove the sealing ring from the lid and inspect it for cracks, tears, or deformities. A damaged ring can cause leaks or prevent sealing.
If damaged, replace it with a new one. The Instant Pot Sealing Ring (ASIN B008FUUQJW) is a reliable replacement option.
Clean the Lid and Valve
- Wash the lid, sealing ring, and steam release valve with warm, soapy water.
- Ensure the steam vent and float valve are clear of debris or buildup.
- Dry all parts thoroughly before reassembling.
Check the Steam Release Handle Position
The steam release handle must be set to ‘Sealing’ for the pot to pressurize. If it’s open or in the venting position, the pressure won’t build up.
Set it firmly to the ‘Sealing’ position before cooking.
Test for Proper Seal and Function
- Close the lid, lock into place, and set the steam release handle to ‘Sealing.’
- Start a quick pressure test by running a short cycle or using the ‘Steam’ function without food inside.
- Listen for the hiss of pressure build-up or any leaks.
