FreeMDU: Open-source Miele appliance diagnostic tools

what we miss is a universal control computer to control those washing machines. It is very often that part that breaks and that is "so expensive that you'd better replace the whole machine".

With a little work, it's sometimes surprising how easy things are to repair. My TV died a few years ago and just refused to power on. I don't really know much about electronics, but I assumed since there were no lights of any kind that it was probably a bad power supply. I opened it up and it turns out the power supply is a separate board with an easily detachable cable. I ordered a new one for less than $40 on eBay by looking at the part number and it only took a few minutes to replace and saved me several hundred dollars.

I'd imagine someone more familiar with electronics possibly could have figured out what specific component was wrong and replaced only that for an even smaller fraction of the cost.
