A similar problem with my girlfriend. There it is the compressor (ultimately a rotating part) that makes contact with the housing somewhere. At least for us, a slight change in position/twist of the refrigerator (very minimal) helps. Adjust the little feet up or down. Otherwise, clearly: the dealer. They are then responsible.
Honest answer ? That's what I'm wondering now too! If the dishwasher is as loud as describes, then I'll lose it. Sorry, I'm usually not a complainer, but I've become sensitive to noises.
a different design and an expensive brand name. Almost all refrigerators now come from one manufacturer
We will also have a few appliances from Gaggenau. The built-in refrigerator not because design does not matter there.
Same issue with the dishwasher. Actually only one manufacturer left...
In the Siemens/Bosch manuals for refrigerators, there are very cute little pictures explaining what each sound means. I think this can also be applied to other brands.
We have the problem with our new No Frost Samsung refrigerator in the new kitchen. When you ask around, it seems to be somehow "normal". Humming, gurgling, etc., I have complained about it...
