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. :)
After having used their repair service for over 10 times for my dishwasher during its warranty period and having broken off its front handle (well, the entire front panel really) after 2 more years, I'm never buying an AEG device ever again. I opened it up and fixed it myself, and oh my god, the whole thing just screamed cost cutting. They literally used the power button of a different model or machine, and then just mounted a different power button on top that presses the underlying one. And of course the load bearing thing that holds the front panel and display onto the door frame is a just two tiny bolts in the corners. Great idea to have the entire thing flex constantly in one place. Absolute junk.
This is the downward spiral for a lot of brands. They sell out to an investor, who uses their brand reputation inertia, reduces cost and quality, etc. There's barely any brands left. IIRC Miele is still one of the few good brands for home appliances, but they're also significantly more expensive. At least for the initial purchase, I'm sure it evens out long term.
How new is your washing machine? Mine (US market, Electrolux branded) displays fault codes through the main 8 segment LCD and makes component tests available from that same diagnostic menu. Service literature was available directly from Electrolux — from a paid service with a free trial, although there are plenty of youtube videos covering the same information.
The blog post that I linked to answers your question.
I was able to get at the diagnostics menu (also explained in the blog), but I had to interrogate a service tech in order to learn how to trigger it (also mentioned in the blog).
The manual did not contain this information and I could not find it via Google.
Where did you sign up for the "paid service with a free trial"?
