I have a compact Bosch stackable washer and dryer model #WFK2401UC. When it goes into the spin cycle, mainly when the revolutions are slower, it makes a rattling noise like there is spare change rattling around in it.
I've had washers that get coins "stuck" in the washer drum fins but I don't see how this is the case on this one. The fins seal pretty tight.
Some searches indicate that it's the bearings in the drum. I'm almost afraid to ask, What could the problem be?
