Original Miele Washing Machine Electronic Power Unit (PCB) Card Miele 7108974

The electronic power board (PCB) part number 7108974 is the main board of Miele W1 and W6 series washing machines. The power board is responsible for managing the motor, heating element, and drain pump. Genuine Miele OEM part – replaces a faulty power board directly, without the need for field reconfiguration.

Is your washing machine completely dead – no lights, no response? First check that there is no tripped circuit breaker. If the problem persists, the power board is likely faulty. Check for compatibility by looking at the model number on the manufacturer’s sticker – the sticker is usually located on the drum door frame, drain filter cover, or the back of the appliance.

When is the power card the cause of the malfunction?

The power card SKU 7108974 often fails with clear symptoms. A machine has completely shut down and no lights are on – this is a classic symptom of a power card failure. Also, error codes F39, F41, F45, F50 or F100 indicate an electronic problem that usually originates from this card. A machine that responds to one button press but “freezes” on the rest – this situation is also typical of a partial power card failure.

Insight from the field (Daniel, Plrom's Miele expert): Power card failure is often caused by a burnt varistor on the board – the result of a transient voltage surge. Before ordering the card, check that the dedicated circuit breaker for the machine is working and that there is no recurring problem in the home's electrical network.

💡 Tip from the experts

Daniel, Plrom's Miele expert , recommends: Before ordering a power card, perform a basic reset – unplug the machine for 10-15 minutes (not 30 seconds!). Miele power cards require a longer time to discharge internal capacitors. Some failures that appear to be power card failures – are actually temporary failures that recover after a full reset.
