It is still worthwhile to try to troubleshoot something like a washing machine these days before calling someone to service it, or buying new.

We just had a ~8 year old washer start dying with an error code, with digging it turned out it was the hall effect sensor on the drum motor that needed replacing. Cost $12 and change and was over nighted from Amazon.

What would have been nice if we got a detailed diagnostic code and not just "FE" on the front panel.

Yeah, and for service manuals to not have this "DO NOT LEAVE WITH OWNER" notes.
