Whirlpool washing machines use a ratcheting-style agitator. The ratcheting pawls (called “dogs”) can wear out with age, or break if you overload the machine. When that happens, the agitator won't rotate. The parts are cheap (less than $5 at appliance repair stores) and the repair is easy. Whirlpool used two ratchet designs, depending on whether the washer has a plain agitator or one equipped with a fabric softener dispenser. Replacing the dogs in a plain agitator is more complicated and that's the one we show here.
Remove the agitator cap by prying up around the outer edge with a small flat-blade screwdriver. Then unscrew the center hold-down (Photo 1). Reach in and remove the ratchet assembly. Turn it upside down and remove the snap-in retaining plate (Photo 2). Then install the new dogs and retaining plate (Photo 3). Then reinstall the ratcheting assembly, tighten and pop on the lid.
If your washer has a fabric softener dispenser, remove it and unscrew the ratchet assembly retaining bolt. Then lift the agitator out and tip it upside down. The ratchet assembly will fall out—there's no retaining plate. Replace the dogs as shown here. Then load the ratchet assembly into the upside-down agitator, flip it over and tighten the bolt. Snap on the fabric softener dispenser.
