Multicooker shows E7 and aborts the program; may occur when trying to start high-pressure modes.

Safety first: Disconnect power before working near the lid lock. Never force the lid open if the cooker may still be pressurized.

Steps to check:

• Inspect lid lock movement: With the unit unplugged and cool, open and close the lid while watching the locking pin (if visible). It should move freely without sticking.
• Clean around the lock: Remove any dried food or grease from the locking mechanism using a soft brush and mild detergent. Dry thoroughly.
• Check lid lock wiring (advanced): Remove the top cover or inner lid panel (depending on design) to access the lid lock assembly. Inspect the solenoid and sensor wiring for breaks or loose connectors.
• Test the solenoid: Using a multimeter, measure the resistance of the lid lock coil. An open circuit indicates a failed solenoid that must be replaced.
• Reassemble and test: After cleaning and reseating connectors, reassemble the lid and run a short pressure program with water to confirm the error is cleared.

When to call a technician: If the lock assembly is mechanically damaged or the control board is not energizing the solenoid, professional diagnosis is recommended.
