Error codeF43 Electronic module fault
ApplianceWasher
Quick answer
F43 on a Miele washer or washer-dryer is an electronic module fault. It may follow an Extras combination the machine does not support.
Model compatibility
Miele reuses codes across series and model years, so F43 Electronic module fault may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What thiscode means
Electronic module fault; may follow unsupported Extras combination in the app.
F43 on a Miele washing machine or washer-dryer is shown as a technical fault with the electronic module. Miele also names one cause tied to the app.
Extras that cannot be combined
If the app was used to combine Extras that the machine does not support, for example “SingleWash” with “Water+”, F43 can appear. Select only the Extras that are available and can be combined on your machine, then restart the programme without that combination.
If that is not the cause
The module fault itself is one you cannot remedy yourself, so book a repair appointment online.

Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
