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.
