Miele W5740

If the machine is going completely dead mid-cycle, then coming back only after you press the power button again, that usually points to a power supply interruption inside the washer rather than a normal wash fault. Because there’s no fault code and it’s not tripping the electrics, the most likely causes are the on/off switch, mains filter, wiring connection, or the main control board/power supply section.

Before checking anything internal, isolate the washing machine from the mains.

1. Check the simple external supply first Make sure the plug is sound, the socket is not loose, and the mains lead isn’t damaged or trapped. If possible, try a different wall socket temporarily.

2. Note exactly when it cuts out Does it always happen when heating, spinning, or after a similar length of time? If it dies when the heater should come on, that can sometimes point to a weak connection or control issue under load.

3. Check for signs of overheating or burning If you are competent to remove the top/lid, inspect the mains filter, on/off switch area, and wiring plugs for heat damage, discolouration, or loose connectors.

4. Pay attention to the door lock behaviour If the machine dies but the door stays locked for a while, the control may have lost power mid-programme. If it unlocks immediately, that can help narrow down whether the board is fully shutting down.

5. Likely internal suspects On this type of fault, the main PCB/power supply section is a strong possibility, though a failing switch or poor connection can do the same.

If you’re not confident testing live supply circuits, it’s best to get a qualified appliance engineer in, as mains electrical diagnosis is needed here. WhitegoodsHelp AI
