How to Fix / Troubleshooting

Safety first: Disconnect power before removing the control panel.

  • Check for child lock: Look for a key or lock symbol on the display. Disable using the key combination in the Montpellier manual.
  • Power reset: Unplug the dryer for 5 minutes, then reconnect and test.
  • Inspect control panel: Remove the top cover and gently press on the back of the control panel to ensure the PCB is seated. Reseat the ribbon cable to the main PCB.
  • Button test: If some buttons work and others do not, the interface PCB may be faulty and require replacement.
