I had a failure in a bosch dish washer which probably would have been control board replacement and $$$$ if I had it fixed. But I happened to look up the issue on the internet and learned that it was a common problem - a bad solder connection on a particular pin on a relay on the control board.
Re-soldered it, and it has been fine for a couple of years.
This is why it’s a good idea to buy the most common model of anything, or whatever enthusiasts buy.
My family has kinda done the same by having a Toyota Corolla and an older bmw 3 series (without the turbo and 4wd thankfully). Also got the base model Bosch dishwasher.
At least if you can’t repair it or part it out yourself, there ends up being some efficient network of buyers that can fix it or at least harvest the remaining good parts.
