Re: Bosch WF02064gb/01 noisy motor?
In most situations new brushes fitted correctly should repair the motor.
Unfortunately if the commutator/armature is damaged or overheats(when the brushes fail)
then the internal fuse can blow or you can damage the motor windings -then a new motor is required.(imho)
There are plenty of sources for new,2nd hand or recon motors via the internet.
Part number for the motor is 141875
