Display shows “PrE” or similar preheat error and the cooker fails to reach pressure.

Safety first: Cancel the program and allow any built-up steam to vent before opening the lid.

• Check liquid level: Open the lid and verify there is at least the minimum required liquid. Add more if needed.
• Inspect gasket and lid: Ensure the silicone gasket is properly seated and undamaged. Clean the lid rim and cooker rim.
• Set valve to sealing: Confirm the steam release valve is in the Sealing position.
• Look for steam leaks: Restart with water only and watch for continuous steam escaping around the lid or valve. Persistent leaks indicate a sealing problem.

If the unit consistently times out on preheat with proper sealing and liquid, the pressure sensor or control logic may be faulty and should be serviced.
