Loud pipes during the spin cycle

This World Cup is on its own during the spin cycle a loud, very unpleasant to the ears of high-frequency whistle (well betw. 2000-3000Hz), especially when revving and at lower revolutions of 800-1200 U / min. Those who intend to set it up in the kitchen or in the bathroom, it should think carefully about.

It trickles even (occasionally?) From the detergent drawer, probably at higher temperatures; because I have the World Cup only very briefly, I have to watch this even further, what is at stake there.

Whether these are specific defects of my WM or general "Features", is still hopefully determined by the already ordered technicians.

Otherwise, the World Cup, however, seems to be in order.
