Bosch washer drum not turning, belt is moving.

[kartoffelsalat]

My Bosch washer sounds like its washing, it fills with water, I can hear the motor running. When the drum should be moving it doesn't and I can hear a clunk clunk clunk sound when the drum should be spinning. I took the back panel off and can see the belt moving and when it's moving I can hear the clunk clunk sound coming from the drum. I've tried moving the drum from the inside and it spins about half way around and then I feel more resistance and it feels like there is something in the way. Any help is appreciated!

Start by looking at the holes inside the drum to see if there is a screw or nail stuck in one of them. It sounds like some obstruction like that.
