Display shows a lid-related message (e.g., "LID" or flashing lid icon) and the cooker will not start a pressure program.

Safety first: Ensure the cooker is cool and depressurized before manipulating the lid.

• Remove and reseat sealing ring: Take out the silicone sealing ring from the lid, clean it and the groove thoroughly, then reinstall it evenly. An improperly seated ring can prevent full closure.
• Check for obstructions: Inspect the rim of the inner pot and the lid mating surface for food, rice grains, or debris. Wipe clean and dry.
• Close lid firmly: Align the lid marks (if present) and rotate until you hear or feel the lock engage. Apply gentle downward pressure while turning.
• Inspect lid detection mechanism: Look for a small tab or magnet on the lid that interacts with a sensor on the body. Ensure it is not broken or missing. Clean any magnetic sensor area with a dry cloth.
• Test in non-pressure mode: Try a non-pressure program (like sauté or slow cook). If it works but pressure modes still show a lid error, the lid detection switch or sensor may need adjustment or replacement.

Warning: Never force the lid closed against resistance; identify and remove the cause of obstruction first.
