Possible Causes
Loose harness between display module and main board, Damaged user interface PCB, Faulty main control board, Electrical noise or surge damage
How to Fix / Troubleshooting
Safety first: Disconnect power before accessing control panels.
- Power cycle: Unplug the machine for 5–10 minutes, then reconnect and test. Some transient communication errors clear after a reset.
- Check connectors: Remove the top cover and control panel. Inspect the wiring harness between the user interface and main board. Reseat connectors firmly.
- Inspect for damage: Look for signs of moisture, corrosion, or burnt components on both boards.
- Replace modules: If wiring is intact but F95 persists, either the user interface or main control board may need replacement. This typically requires programming and should be done by a Miele technician.
