Safety first: Cancel the program and ensure there is no pressure before opening the lid.

• Verify valve position: Set the steam release valve to Sealing.
• Check sealing ring presence: Ensure the silicone sealing ring is installed and properly seated.
• Free the float valve: Clean around the float valve and ensure it can move freely up and down.
• Increase liquid: Add more liquid to meet the minimum requirement and restart the pressure program.
• Monitor first minutes: Watch for steam leaks. If steam continuously escapes, replace the sealing ring or float valve cap.
