Bosch WFD2061 Washing Machine - Very Noisy

I have a 3 year old Bosch WFD 2061 washing machine.
In the last couple of weeks it has become very noisy.
when the drum rotates it seems to catch.
When on Spin it sounds more like a machine gun!!!

Today the drive belt came off, when I put it back on, the machine runs OK, but is still as noisy.

I can't think that it's a bra wire, as no Bras have been washed in the machine.

I hope someone will be able to help me out.

Thanks

Jim

Check for play in the inner drum. Rotate it by hand, does it feel rough?
If there's a lot of play and it feels rough then bearings are gone.

Thanks for that.

I've rotated the drum as you said, it feels fine, very smooth.
Can't feel any play.

The noise is really bad on rinse/spinning, not really that bad on wash.
