"I don't feel like dancing"
Hah, how I like that song...
But on topic: I could actualy be both. A starting tub bearing failure with only a few balls being wrong causing noise. Heard this on several Miele machines and kind of sounds like your noise.
These few balls in the bearings "fly" around inside the bearing as they got to small and knock against everything else at high frequencies. This is caused by an uneven wear-out again caused by uneven material mixes in these bearing-balls and\or minor producing errors in the bearings housing where the balls rub against the metal surfaces.
The same could of course happen to motorbearings.
But if it happens that early in a life-span, you either put a ton of mileage on the machine (Do they have a run-time counter as it is common in the EU?) or there was a production error.
And, back of topic, yes, I sad balls...
