they are in the motor that if fitted on top of the drum,
be sure you unplug the machine before you remove the top of the machine,they are very easy to replace,we change them with the motor in place,but you may find it easier to remove the motor,they are in either black or white brush holders,on the side of the motor,you press the lug on the holder with a small screwdriver,and with draw the holder,remove the wire from holder before you remove the holder,
