Update - Main outer drum leak repaired using Milliput.
However during fast spin, on each revolution, there is a knocking noise, which gets extremely loud at 1200 rpm, like a machine gun going off !
Is it possible that there is some 'alien' object in between the inner and outer drums ? e.g. a coin ?
If so, how can access be gained to remove such an item ?
