Dishwashers, washing machines, dryers, threadmills, all have common issues and fairly simple fixes, if spare parts are available. I'm actually surprised there aren't general purpose boards, electric motors, heaters pumps etc out there that could be just swapped in. As long as the enclosure is in presentable state, that is

I found a place* that repairs appliance control boards. They replace the caps and relays and then reflow the whole thing. They give a 2-year warranty, which is 24 times what you get buying a new board. FedEx the board to them, they turn it around in a day and FedEx it back. We no longer dread the oven throwing errors at Thanksgiving, etc.

* Circuit Board Medics, but I understand there are others.

I recently came across a slew of replacement boards that basically completely take over your washing machine and runs it. Some Chinese generic stuff that is meant to install in any machine missing its original control board.

The Chinese seem to be pumping a lot of those type of things out lately. I have recently found a driver for quite niche of CRT.
