to gain access to the fan/motor you will have to remove the top and rear panels on the appliance .you will need a 8mm socket to remove the screws .two screws are located behind plastic covers on the bottom and the rest are visible on the bottom /sides/top.you will see one that goes into the fan/motor casing aswell .once all these are removed you can remove rear panel ,there may also be two phillips screws securing the water inlet valve/solenoid to the rear panel.
