Just changed the brushes on my WD62P. Not quite as easy as Struan described, but not bad....
remove the screws (x3) at the back top of the washer.
slilde the top off.
The motor is held in place by THREE bolts - one at the top tensioning the drive belt and TWO below attached to the drum. Remove the electrics connection block from the motor, unclip the connections from the brushes and unfasten the bolt holding the earthing tag - this should have removed all the electrics from the motor.
I had to take the back of the washer off to get access to the bolt heads under the motor - remove the numerous screws holding the back on and slip off. However, even when you remove all three bolts, the motor will not slip off as there is a plate on the underside front bolt housing holding the motor in place.
However, the motor will now pivot enough to (just) get access to both brushes. Swing the motor back away from the drum and slip a screwdriver behind the brush to release the clip, then pull up and off.
Swing the motor towards the drum and remove the other brush in the same way. (this is the hardest bit - there is not much space to work in and you have to have small enough tools to get the brush unclipped and pulled out). From then on it is easy - slip in the new brushes, fold back the retaining tags to release the brushes then re-assemble as a reverse of the above. One working washer-dryer.
