> If it's a brand of good quality (Miele, Henry, DeLonghi) it probably does not need to be advertised, as word of mouth and price point is generally enough.
Nah, they advertise (probably) for a similar reason as car brands do, to make the people who bought it already feel better and more reassured about their choice.

I'm guessing high-end appliance brands are enough of a niche market that it just doesn't make sense for them to advertise in relatively unfocused ways. You'll see plenty of ads for high-end appliances and cookware if you frequent gourmet-oriented websites and magazines.
