This DIY washer repair guide explains how to replace the agitator dogs in a top-load washer. The agitator dogs grip the teeth inside the agitator to create a one-way ratcheting motion in the upper part of the agitator. That one-way motion combines with the back-and-forth motion at the bottom of the agitator to move garments through the water during the agitate cycle. If the top part of the agitator moves in two directions, the agitator dogs have likely worn out. Replace the agitator dogs with a manufacturer-approved replacement part.
Use these steps to replace agitator dogs in Kenmore, Whirlpool, Maytag, Estate, Crosley, Roper and Amana top-load washers.
