dishwasher would not shut down, it stayed on first cycle

First I turned off the breaker so all the power was off to the dishwasher. Then I removed the door handle, which has one screw on the bottom side. Next i pulled the timers handle off, just pull it straight out. Next i opened the door on the dishwasher and removed the 8 screws on the back of the door. Next i pulled the door panel apart to get to the timer. I disconnected the three plugs from the old timer, then unsrewed the two screws holding the old timer in place. Put the new timer in, and put it all back together. The new timer works great and it solved the problem
