Ensure Proper Lid Placement
- Close the lid securely, aligning the marks or arrows if your model has them.
- Make sure the lid is fully sealed and locked into place, with the steam release handle in the ‘Sealing’ position.
- Double-check that the lid isn’t warped or cracked, which can prevent a proper seal.
Clean the Valves and Steam Release
- Remove the steam release valve and clean it thoroughly to remove any debris or blockages.
- Use a small brush or toothpick to clear the valve opening.
- Ensure the valve moves freely and is reinstalled correctly.
Test the Seal
After reassembling, add a small amount of water, close the lid, and select a short cooking cycle. Watch for steam escaping from the edges. If it’s sealed properly, the pressure indicator will rise and stay up.
Additional Tips & Warnings
- Always use the correct size sealing ring for your model—this model uses the same ring as the 5 & 6-quart versions.
- A damaged or old sealing ring is a common cause of sealing failure. Replace every 12-18 months or sooner if damaged.
- Never attempt to force the lid closed if it doesn’t seem to fit properly—this can cause safety hazards.
