Display shows a lid-related error (e.g., "LID" or flashing lid icon); cooker will not start pressure programs.

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

Steps:

• Open and close the lid several times, ensuring it aligns with the body marks and that the handle fully rotates to the locked position.
• Listen for a distinct click from the lid lock when closing. If no click is heard, the lock lever or microswitch may be misaligned.
• Inspect the lid lock slot and latch for food debris or hardened residue. Clean carefully with a small brush and damp cloth.
• If accessible, remove the top cover or front panel to locate the lid lock microswitch. Check that the actuator from the lid mechanism fully depresses the switch when locked.
• Adjust the position of the microswitch bracket slightly if needed so that it is reliably triggered by the lid lock.
• Inspect the wiring harness from the switch to the control board for damage. Repair or replace as necessary.
