Hi
Disconnect power supply, remove lid to access motor. Now there is a special tool that Hotpoint engineers use for brush removal, but they can be removed with a very small screwdriver! The idea is to release the plastic brush holder clip that locks the brushes to the motor, the slide out the brushes before finaly undoing electrical connection. The bottom brush is slightly more fiddly, if in doubt, it's easy enough to slacken the motor itself so it swings down to make access for the brushes easier!
Make sure the power supply has been turned off before you start tho! Good Luck
