U01 appears and the unit beeps; lid may not be closed properly.

Safety first: Ensure your hands are clear of the rim when closing the lid.

• Remove obstructions: Check the rim of the inner pan and the lid gasket for rice grains or food debris. Wipe clean with a damp cloth.
• Check gasket seating: Make sure the silicone or rubber gasket is fully seated in its groove around the lid.
• Close firmly: Lower the lid and press down until you hear a positive click from the latch.
• Restart: Press CANCEL/RESET if available, then select your program and press START again.

When to call a technician: If U01 appears even when the lid is clearly closed, the lid switch may be misaligned or faulty.
