How to replace a dishwasher timer
This DIY repair guide explains how to replace a dishwasher timer. The timer is behind the cycle control knob in the control panel. A small electric motor inside the timer advances the control knob and rotates cams inside the timer. The cams turn on and off the electro-mechanical components in the dishwasher such as the wash pump, drain pump, water inlet valve and heating element. Replace the timer with the manufacturer-approved dishwasher part if it won’t advance or if the cams fail to properly turn on and off components in the dishwasher.
This guide shows the GE and Kenmore dishwasher timer replacement procedure. You also can use the same basic process to replace the timer in Whirlpool, KitchenAid, Frigidaire, Electrolux, Maytag and Amana dishwashers.
To find the dishwasher timer replacement part you need, search for your model number to find a complete list of the repair parts for your dishwasher.
Instructions

Shut off electrical power
Flip the house circuit breaker switch to the Off position to completely disconnect electrical power to the dishwasher (instead of a breaker, some older homes have a fuse that you remove from the fuse box). To verify that power is disconnected, make sure the display on the control panel can't be activated.

Remove the timer knob
Pull the timer knob straight off of the front of the control panel.

Attach wires to the new timer
Attach the wires to the new timer the same way they were connected to the original timer.
Reinstall the timer mounting screws.

Reattach the outer door panel to the inner door panel
Close the outer door so that it mates up with the inner door panel.
Grasp the inner and outer door panels and open the door. Keep the inner door panel postioned against the outer door panel.
Line up the mounting screw holes and reinstall the screws that hold the inner door panel and outer door panel together.
Tip: The mounting screws that fit in the bottom corners of the door are machine threaded screws. These machine threaded screws must go back into the bottom corners of the inner door panel to properly secure the inner door panel to the door frame. - 08.

Slide the latch handle knob back onto the door latch handle and reinstall the screw.
