I used to work with a guy who was a consultant to all sorts of companies, including many of the large washing machine brands. He said two things that stuck with me….
1. He would never leave a washing machine on in an unattended house, unless it was a Bosch. He didn’t rule out other brands, just that he was confident that a Bosch wouldn’t leak/catch fire. Of course there is a bit of irony there, as I think it was Bosch dishwashers in the news recently for catching fire. Not seen him since to ask him about that.
2. Secondly, and probably most interestingly, was that most of the major manufactures (including Bosch and Miele if memory serves) farm out their cheaper models to other companies. Its not till you get mid-range and above that you get the real deal. This, I think, is evident in the fact that the longer warranty’s only come on these models, and not the bottom of the range ones.
YMMV
