Possible Causes
Unresponsive Start button on touch panel, Door/basket not detected as closed, Faulty main PCB logic, Child lock or safety mode enabled
How to Fix / Troubleshooting
Safety first: Disconnect power before removing the control panel.
User-level checks:
- Confirm the basket is fully inserted and the door is closed.
- Check the user manual for any child lock or safety lock feature and disable it if active.
- Try pressing other buttons to see if the panel responds normally.
Control panel inspection:
- If only the Start button is unresponsive, the touch panel may be worn or damaged.
- Remove the control panel and inspect the ribbon cable and connectors for damage or looseness.
Corrective action:
- Replace a faulty touch control panel assembly if specific keys no longer respond.
- If multiple keys fail or the display behaves erratically, replace the main control PCB.
