Hello, I was hoping someone might be able to help with this problem.
I have taken the turbine head apart and it seems as though the fan is fine (from reading other posts this seems a common fault), it is driving the belt but the cam that connects to the brush shaft is not fixed.
Is there a way of fixing the cam to the shaft or indeed replacing that mechanism? It'so quite difficult to access because of the brush fixing attachments either side of the plastic body cannot seem to be separated.
I'll attempt to attach some photos:
