Washer-dryer will not start cycle; display works but Start button does nothing.

Safety first: Ensure hands are dry when operating controls.

• Step 1 – Check display icons: Look for a key or lock symbol indicating child lock. Disable it according to the user manual (often by holding specific buttons).
• Step 2 – Confirm door closure: Open and firmly close the door until you hear the latch click. Check for obstructions around the gasket.
• Step 3 – Test door lock: Start a program and listen for the door lock engaging. If there is no click and the door symbol flashes, the door lock assembly may be faulty.
• Step 4 – Check Start button: If other buttons respond but Start does not, the button or control panel PCB may be defective and require replacement.
