This reminds me of my own troubles with my AEG washing machine.
Probably, the most important lesson (for someone who wants to fix their washing machine ASAP) that I learned from that was that there are non-userserviceable error codes and you need to perform an undocumented procedure on your machine to get those codes. I wrote about it in more detail here: https://andri.yngvason.is/repairing-the-washing-machine.html
I would have loved to have an open source diagnostics dongle for my AEG. Maybe next time I'll try and make one. :)
