Miele did go through a period of rebadging Bosch. one of which I was unfortunate to purchase 4 years ago These apparantly suffered lots of sensor failures and ours broke its hinge which dropped the door on one off my kids ( did not hurt him), and then lost its gas inside the foam filling
However AUIU Miele now only sell Liebher now and the mone we have got looks far better constructed. I imagine they dropped Bosch when they discovered their Fridge freezers have a 3 year life as our previous Bosch did and it was in serious danger of wrecking their reputation which serves Bosch right. in their fridge freezer falling to bits after 3 years so we bought a Miele not knowing it was a rebadged Bosch
Miele could not fix this rebadged 4 year old Bosch under warranty so replaced it with a Liebher with 2 years Warranty and took the old crappy one away
I iamgine it will live for at least 10 years
