Display shows a lid icon or LID error and the cooker refuses to start pressure programs.

Safety: Ensure the cooker is unplugged when inspecting the lid mechanism.

• Verify correct closing: Follow the user manual to close and lock the lid. Rotate until you hear a clear click and the lid mark aligns with the body mark.
• Clean lid area: Remove food debris or dried sauce from the lid rim, hinge, and locking slots. Sticky residue can prevent full engagement.
• Inspect lid sensor: Locate the lid position sensor or magnet/switch pair (often near the hinge). Clean the area and ensure the magnet is not loose.
• Test switch: If accessible, test the lid switch with a multimeter while opening and closing the lid. Replace the lid position switch if it does not operate reliably.
