If you are REALLY handy, look for a stuck relay. The timer may control the motor directly without triggering a relay. If that's the case you need a new timer. Usually the wiring diagram (schematic) is on a folded piece of paper stuck under the dishwasher or sometimes in back. I have seen a lot of stuck relays AND bad timers. Good Luck
