After checking the temperature of each heatsink in the control box (which, despite the decorative ventilation slits is taking the term "enclosure" rather literally) I decided to venture into the streaming business and start with something simple: air.
While I love hotspots for my tablet, those in the control box are less useful. Seeing that a whole washing cycle was completed after I brought some desperately needed fresh air into the domestic machine washing business, I think I found the culprit responsible for the dwindling loyalty of my washing machine.
Now I need to streamline my streaming activities...

👍 still might be an aging component - producing too much resistance and thus overheating. Won't be a solution for the long run. An IR thermometer or a heat cam would be nice to check which component is running hot over the washing cycle.
Jörg Walossek I used my IR thermometer to check the heatsinks, that's why I brought the fan out. I know it's not a final solution, but at least it's a beginning, now I know where to go on.
=)) I should have known you're already on with the IR thermometer! Maybe you can figure out what component is the overheating culprit.
I wonder if you find some aged capacitors being the reason...
Michael Kukat the caps look good from the outside, but I can't check them - epoxy... I'll see how far I can get, at least I can do laundry again, properly.
During the years of repairing capacitor related problems, I have seen many capacitors looking like fresh from the store but way off specs, sometimes zero capacity. Metal film and electrolytic caps. Sometimes even ceramic ones. And I had plenty of leaking electrolytic caps already destroying the PCB but still wird the nominal capacity.
Capacitors are evil :)
But I have an oscilloscope that gets hot in the PSU and the high speed signal processing for no detectable reason, so semiconductor aging might also be an issue.
If any semiconductor/diode gets hot double check the operating voltage... But you know that. Can be a malfunctioning power supply. And back to the capacitors. 😂
