The timer of Dishwasher is a complex component, so you shouldn't attempt a do-it-yourself repair. Test the timer with a VOM set to the RX1 scale. To gain access to the timer, remove the front control panel. The timer is directly behind the main timer control knob. Disconnect one of the timer's terminal wires and clip one probe of the VOM to each terminal. If the meter reads zero, the timer is working. If the meter reads higher than zero, the timer is faulty and should be replaced.

If possible, use the same procedure to test the selector and cycle switches. The wiring hookup, however, may be too complicated to figure out on either of these switches. If you aren't sure you can deal with these switches, call a professional service person. Replace a faulty timer -- or a faulty control switch -- with a new one made for the dishwasher.

The timer is connected to several wires that supply power to operate the various functions of the dishwasher. To replace the timer, have a helper hold the new timer next to the old one. Connect the wires of the new timer one by one, removing the old wire and connecting the new, to make sure you connect the wires correctly. The wires may be friction-fit on the terminals. If they are, use long-nosed pliers to remove the wires. Don't pull up on the wires, or you may break the connection between the wires and the clips

After connecting the wires, set the new timer in position, secure it the way the old one was secured, and replace the control panel and knobs.

If your dishwasher won't fill with water properly or isn't drying the dishes, you most likely have a valve or heating element problem.
