Possible Causes
Door not fully latched, Faulty door switch, Defective start button or touchpad, Control lock (child lock) enabled
How to Fix / Troubleshooting
Safety first: Disconnect power before mechanical checks.
- Check for control lock: Look for a key or lock icon on the display. Disable child lock per the user manual (often by holding a specific button combination).
- Ensure door is latched: Close the door firmly until it clicks. Remove any items blocking closure.
- Test start button: Press other buttons to see if they respond. If only Start is unresponsive, the user interface panel may be faulty.
- Door switch test: Gently press on the door while pressing Start. If the cycle begins only when pressing, the door latch switch is likely failing.
Replace the door latch assembly or user interface panel if they do not reliably start the cycle.
