That's their service department. The build quality is an entirely different story and Miele stuff in stores today is not of the same quality that it was 22 years ago. And it definitely isn't the same as it was 50 years ago (amazingly: some of that stuff still runs today).

Miele had a definite edge on build quality, that means that services are fewer and farther between than with other brands given the same amount of use.

The joke was that if you wanted to armor plate your car you could do so with the side panels of Miele washing machines. Not too far from the truth, they were also much heavier than competitor gear. But those days are - as far as I can tell - over.
