Not completing the wash cycle

Does this happen every time or once in a while? If it happens everytime, I would guess there is a shorted spot in the timer. If you can put it into the spin cycle manually, then the motor is not shorted. It will be hard to diagnose it from long distance, but if it is tripping the house breaker it has a dead short somewhere. If it only happens sometimes, check to see what else is on the circuit that might be running at the same time. It pulls the most amps when it goes into spin, spiking around 16-20 amps. If you have other things running on a 20 or 30 amp breaker it could just be the curcuit is overloaded at that point or the breaker is weak. If we can narrow it down to the timer, it is a pretty simple repair, but some of the timers are pretty expensive. Post back with the exact model number if you need more help.
