How to Fix / Troubleshooting

Safety: Unplug the appliance before removing the control panel.

Steps:

  • 1. Power cycle: Unplug for 5–10 minutes, then reconnect. Transient communication faults can sometimes clear.
  • 2. Reseat ribbon cable: Remove the front control panel and access the flat ribbon cable. Disconnect and reconnect both ends, ensuring they are fully seated.
  • 3. Inspect for damage: Look for kinks, cracks, or burn marks on the ribbon and both PCBs. Replace damaged cables.

Resolution: If reseating and replacing the cable do not resolve E14, either the UI board or main control board must be replaced. This is typically a technician-level repair.
