Bosch WAS24460 noise

[Ksh]

Please can someone kindly comment on this Bosch washing machine noise when on a spin cycle. I suspect it is bearings but the noise disappears when on faster speed cycles so before I buy the costly bearings I would appreciate some expert advice. Thank you.

Check the drum pulley isn’t slightly loose. Check the condition of the belt too as they can cause funny noises. 

Take the belt off and spin the drum by hand from the front. Turn it slowly and lift it all the way round its circumference to feel if the drum has more give at any point indicating a possible problem with the drum spider.

So I rotated the drum by hand as you said and there is a notchiness as it is rotated at a certain point. By notchiness I mean that I can lift the drum at a specific point and it makes a 'knocking' noise. Does this indicate a spider issue?

It could be a cracked drum spider or a spider coming away from the drum. It would have give and lift at a very specific point if so. There are 3 points where the drum spider attaches to the drum.
