I love reverse engineering efforts, and like to partake myself from time to time, so I'm very happy to see this; but, for a fraction of an infra-red-wave period I thought Miele had decided to be cool and open source some diagnostic tools for everyone to benefit.
If I'm not mistaken, they were the first (and only?) to open source 3d models for vacuum cleaner accessories.
In contrast I had a great experience repairing a Smeg stove and buying all the necessary parts directly from them, so it’s not like it’s impossible.
False on both counts.
Both Apple and Miele offer Self Service Repair.
Specifically in the case of Miele (since its the subject of this thread), you can buy spares directly from Miele. They openly show exploded parts diagrams on their website, and if you can't find it, you can call their parts sales number.
The instant they stop selling a model, all the documentation is thoroughly whisked away and inaccessible to customers or anyone a customer can reach.
And they never gave me that kind of documentation so it’s not even something I “should have” saved myself.
