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?

I found the problem. Indeed it was change in the washer. I removed the lower trim panel, drained the water out (there is a small hose with a cap), then removed the cover for the pump. Out fell a penny. That's right, a single penny made all that noise. The edges of the penny were silver from rolling around in the pump area. What uncovered this process for me was the manual detailing how to clean the pump: https://www.manualslib.com/manual/19311/Bosch-Wfk-2401.html?page=19#manual What a relief! Machine works great, no issues or noise now!
