Display shows E7 and the unit beeps; basket is inserted but cooking will not start.

Safety first: Disconnect from mains before opening the housing.

• Check basket insertion: Remove and firmly reinsert the basket/drawer until it clicks. Ensure no food debris is preventing full closure.
• Inspect actuator: Look at the side or underside of the drawer where a plastic tab or protrusion engages the internal microswitch. If the tab is broken or worn, the switch will not be pressed. Replace the basket/drawer assembly if the actuator is damaged.
• Test microswitch: Access the internal basket detection microswitch. With the unit unplugged, use a multimeter in continuity mode across the switch terminals while manually pressing the actuator. The switch should open and close reliably. Replace if intermittent or non-functional.
• Check wiring: Verify the switch wires are firmly connected to the main board and not damaged.
• Control board: If the switch and wiring are good but E7 persists, the input circuit on the main control PCB may be faulty and require replacement.
