Display shows a lid-related message (e.g., “LID” or lid icon) and the cooker refuses to start pressure programs.

Safety first: Ensure the cooker is unplugged and cool before adjusting the lid.

• Re-seat the lid: Open and close the lid several times, making sure to align the arrows or marks and rotate fully into the locked position.
• Clean hinge and rim: Inspect the hinge area and the top rim of the cooker body for dried food or foreign objects. Clean thoroughly with a damp cloth.
• Check lid lock movement: Observe the locking mechanism as you open and close the lid. It should move smoothly without sticking.
• Test non-pressure mode: Try starting a sauté or brown program (if allowed with lid open). If that works but pressure modes still show a lid error, the lid sensor is likely at fault.

If the lid message remains even with a clean, properly locked lid, the lid detection switch or hinge sensor may need adjustment or replacement by a technician.
