Periodic reminder just leaving shit unplugged for hours does fix things. Fucking capacitors/resettable fuses are everywhere and you have to defeat them with waiting it out with ALL POWER REMOVED. Even your USB devices and screens with their own power. No power in contact with anything that’s connected.
Fixed a washing machine like this. Just fixed my motherboard despite me hitting the reset to defaults button AND removing the battery.
Sometimes you got to just give things a time-out in a corner to think about what they did.
