This thread was marked as solved. Here's a summary of the problem and the fix, generated from the discussion below.
Miele W5740 cuts out mid-cycle with no display fault
- The problem
- The Miele W5740 starts normally but goes completely dead part way through any programme. It does not trip the house electrics or blow a fuse. Power can be restored by switching it back on at the front, after which it can be started again.
- Likely cause
- The accepted reply suggests an internal power supply interruption rather than a normal wash fault. The most strongly supported possibilities mentioned are the on/off switch, mains filter, wiring connection, or the main control board/power supply section. No exact failed part was confirmed.
- What fixed it
- Recommended action was to isolate the machine from the mains, check the external supply first, and inspect accessible internal areas for heat damage or loose connections if competent to do so. Because the fault points towards mains electrical diagnosis and no confirmed repair was posted, further diagnosis should be carried out by a suitably qualified appliance engineer.
- Checks to try
- Checked that the fault does not trip the electrics or fuse
- Advised to check plug, wall socket and mains lead
- Advised to note whether the cut-out happens at a particular stage such as heating or spinning
- Advised to inspect mains filter, on/off switch area and wiring plugs for heat damage, discolouration or loose connectors
- Advised to observe door lock behaviour after the machine dies
- Parts or tools mentioned
- on/off switch
- mains filter
- wiring connection
- main control board/power supply section
Safety: Isolate the washing machine from the mains before any internal inspection. Further diagnosis should be carried out by a suitably qualified appliance engineer.

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
