Except that they clearly never tried to incentivize customers into frequent upgrades. Quite unlike most other brands that have a habit of dying months out of warranty.

Anecdata: In my wive's house, we have a Miele wasching machine from the year 2000. Its been used daily. It is as good as on the day it was purchased - quiet, and does not vibrate even when spinning at its max 1600 rpm. Its pretty amazing.

I believe when it was last cleaned they did install new firmware -- though to be entirely hoenest, I doubt a lot of people really know or care how efficient their wasching machines are -- water is way too cheap.
