As I said: I don't want to be at their mercy even if they handled my case well. What especially bothered me is the fact that among the parts changed was an item (the controller) which had 250€ on the price list. It apparently had not been sealed water tight although construction wise it could be exposed to hot vapour. For that price point I expect everything being IP67, parts and connectors. It's not exactly hard, I've done this myself. The parts are only protected by a cooling fan designed to keep also the moisture away. For some reason, the fan did not work at one cycle. There is no detection in place to detect this, leading to a bricked oven. In my book this is engineering fail on many levels. Edited to add: Miele offers a 10 year warranty extension, at roughly 20% of the original price. It is left as an exercise for the reader what such a premium means for the expected failure rate...
