Could be any one of a dozen different things i.e. no power at plug, broken power cable, blown fuse, door lock not working, faulty control board, broken wiring somewhere. Shall I go on or do you now see that this sort of question is impossible to diagnose without actually seeing the machine. If you haven't got test equipment and don't know how to fault find a problem then call some one out to do it.
