Display shows 'LID' or a lid icon and the cooker will not start pressure or rice programs.

Safety first: Ensure the cooker is unplugged before manipulating the lid lock mechanism.

• Close lid firmly: Open and close the lid several times, pressing down until you hear a clear click from the lock.
• Clean lock area: Use a damp cloth to clean the lid hook and the lock slot on the body. Remove any dried food that may prevent full engagement.
• Check lock movement: With the lid open and the unit unplugged, gently move the lock hook to ensure it moves freely and springs back.
• Sensor inspection (advanced): If the lock is mechanically sound but 'LID' remains, the lid sensor switch or magnet sensor may be faulty and require replacement.
