How to Fix / Troubleshooting

Safety: Disconnect power before removing the control panel or top cover.

Steps:

  • Power cycle: Unplug the refrigerator for 5–10 minutes, then reconnect. Observe if F8 returns.
  • Inspect control panel: Remove the top trim or control housing according to the user manual. Check the ribbon cable or wiring harness between the display panel and main board.
  • Reseat connectors: Carefully unplug and reinsert the ribbon cable, ensuring it is fully seated and locked.
  • Check for moisture: Look for signs of condensation or liquid spills behind the control panel. Dry gently if present.

If F8 persists, either the user interface board or main control board is likely defective. Replacement and programming should be performed by a Miele technician.
