Ensure Lid Is Properly Aligned
- Close the lid securely, aligning the arrows or marks as indicated by your model.
- Turn the lid clockwise until it clicks into place, confirming it is fully seated.
- Check that the rubber gasket is evenly positioned around the lid for a tight seal.
Clear the Valve and Vent
- Inspect the steam release valve and float valve for food debris or blockages.
- Use a toothpick or small brush to clean out any buildup.
- Ensure the steam vent is in the ‘Sealing’ position, not ‘Venting.’
Avoid Overfilling
Check the maximum fill line on your inner pot. Do not exceed this limit, as overfilling can prevent proper sealing and cause leaks.
Remove excess ingredients if needed and adjust your recipe accordingly.
Test the Seal
- After completing the above steps, close the lid securely.
- Set the cooker to a short pressure cycle (e.g., 5 minutes).
- Observe if the lid maintains pressure and no steam escapes from the sides.
