Display stuck on “PrE” or “PREHEAT” for an unusually long time; may time out with an error or never reach pressure.

Safety first: Ensure the cooker is not under pressure before removing the lid. Unplug the unit.

• 1. Check steam release position: Verify the steam release valve is set to the Seal position, not Vent.
• 2. Inspect lid gasket: Remove the silicone lid gasket and check for cracks, deformation, or food buildup. Clean it with warm soapy water, rinse, and dry. If it is stiff or damaged, replace it.
• 3. Examine float valve: Ensure the float valve moves freely up and down and that its small silicone cap is intact and flexible. Replace the float valve and cap if worn.
• 4. Check lid seating: Make sure the lid is properly aligned and locked. Look for warping or damage to the lid rim.
• 5. Water test: Add 2–3 cups of water and run a pressure program. Watch for visible steam leaks around the lid. If leaks persist, replace the lid gasket and re-test.
