Possible Causes

Faulty door switch, Defective Start/Pause button, Broken wiring in start circuit, Failed relay on main control PCB

How to Fix / Troubleshooting

Safety first: Disconnect the dryer from mains before testing switches or opening panels.

  • Confirm power and settings: Ensure the dryer is plugged in, the door is fully closed, and a valid program is selected. Check that the child lock is not active.
  • Test door switch: Listen for a click when closing the door. Access the door switch and test continuity with a multimeter when the door is closed. Replace if faulty.
  • Check Start/Pause button: Press firmly and repeatedly. If unresponsive, access the control panel and test the switch or keypad contacts.
  • Inspect wiring and PCB: Check the harness from the door switch and control panel to the main PCB for damage. If switches and wiring are good, the start relay or PCB may be defective and require replacement.
