Display flashes "CLOSE" and beeps when trying to start; cooker will not proceed.

Safety first: Ensure the cooker is not under pressure when adjusting the steam release valve.

• Set valve to Seal: Rotate or flip the steam release knob to the Seal position as indicated on the lid markings.
• Check valve seating: Remove the valve cap and verify that the stem is correctly inserted and can move freely. Reinstall firmly.
• Inspect valve gasket: Look for a small silicone ring or gasket on the valve. Replace if cracked, hardened, or missing.
• Clean valve channel: Clear any food residue from the valve channel that might prevent full seating.
• Replace valve assembly: If the valve cannot be set to a stable Seal position, install a new Gourmia steam release valve assembly.
