However, Miele has a reputation that they don't care about warranty; if it breaks, even after warranty, they may fix it for free unless it's clear you've done something wrong (like it breaks because you didn't do regular maintenance and clean the filters as you should).

Worked for me at least: when I had a problem, and I will buy the same brand again.

There were other similar brands but they've all gone bankrupt or been acquired (I had a UPO Pesukarhu washing machine which was maybe 15 years old when I bought it second-hand as a poor student, and it worked another 10 or so for me, and I only got rid of it because the 1970's color of the device didn't fit the interior in our new house, and later I regretted this. Now I've had the Miele for around 10 years.)

Some of the control boards can be repaired, see https://youfixit.eu/en/ I did this after an electrical surge blew out a component.
