How to Fix / Troubleshooting
Safety first: Unplug the dryer before removing the control panel or accessing internal wiring.
- Check child lock: Refer to the user manual to see if a child lock icon is displayed. Disable the child lock by holding the specified button combination.
- Verify door closure: Ensure the door is fully closed and latched. Try gently pressing on the door while pressing Start.
- Test Start button: If accessible, remove the control panel and test the Start button switch for continuity when pressed. Replace the user interface PCB if the switch is faulty.
- Inspect control board fuse: Some models have a low-voltage fuse on the control board. Test and replace if blown, investigating the cause.
- Check wiring to door lock: Ensure the door lock connector is secure and wires are intact.
