Possible Causes

Stuck or shorted keypad button, Moisture ingress into control panel, Damaged control panel ribbon cable, Faulty display/control PCB

How to Fix / Troubleshooting

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

Step-by-step:

  • 1. Inspect buttons: Check if any buttons feel stuck or do not click properly. Wipe the panel with a dry cloth.
  • 2. Dry out moisture: If the panel has been exposed to condensation or spills, leave the unit unplugged in a warm, dry room for 24 hours to allow moisture to evaporate.
  • 3. Check ribbon cable: Remove the top/front cover to access the display board. Reseat the flat ribbon cable connecting it to the main PCB.
  • 4. Test again: Reassemble and power on. If F2 persists and buttons still do not respond correctly, the control panel PCB is likely faulty.
  • 5. Replace control panel: Order the correct De'Longhi control panel/display board assembly and swap it, transferring any mounting hardware.
