How to Fix / Troubleshooting

Safety first: Unplug the washer before removing the control panel.

  • Power reset: Leave the washer unplugged for 10 minutes to allow electronics to reset. Reconnect and test.
  • Inspect control panel: Remove the top cover and, if necessary, the front fascia to access the user interface board. Check for signs of moisture, corrosion, or burnt components.
  • Check connectors: Reseat the ribbon cable or wiring harness between the UI board and main PCB. Ensure connectors are fully engaged and not damaged.

If E14 persists and the display or buttons remain unresponsive or erratic, the user interface board or main PCB may need replacement. This should be done by a qualified technician.
