you will have to unplug the appliance first and take the back panel off. i think on this model there is 4 screws.
you will need a 13mm spanner to remove the two bolts holding the motor in place.
once removed unclip the connection block to the motor
remove motor.
at the back of the motor you will see two carbon brushe holders.
remove these and look for any sign of wear, original lenth of these is about 4"

See the source. Hope it helps.
