Hi Kelvin, if you look alond the edge of the steel inner door,there may be a model number.I think it may be an ADP8332 or its family.If the motor runs and the water just bubbles out of the sparay arms,you will need a new recirculation motor,that is quite dear.If it fills and then you get a humming noise it may be the recirc motor or its start capacitor.Hope this helps, All the best.
