Understanding the Problem
Top‑load washers with a two‑piece agitator use small plastic one‑way pawls called agitator dogs (or directional cogs) that allow the upper portion of the agitator to ratchet one way and lock the other. Over time these little dogs wear or break, allowing the agitator to spin freely or slip during the wash cycle, so the clothes won't agitate properly. Replacing the agitator dogs is a common, inexpensive repair. The job typically requires removing the fabric softener cap (if present), removing the agitator retaining bolt, pulling the agitator assembly, swapping the worn dogs in the lower agitator half (or replacing the entire cam/dog assembly), and reassembling. With basic hand tools the repair is usually straightforward and can restore full agitation without replacing the whole agitator or transmission.
Common Symptoms
Agitator slips or spins without moving clothes, weak/no agitation, clothes bunched at the side of the tub, unusual grinding or clicking noise during agitation.
Common Causes
- Worn or broken agitator dogs (directional cogs) that no longer engage
- Cracked or worn agitator cam or splines inside the agitator
- Damaged agitator bolt, coupling, or splines causing intermittent engagement

Helpful Repair Tip
Before disassembly, run a short agitation cycle and watch the agitator (with the lid open and power off before touching) — if it spins freely in both directions or ratchets only faintly, the dogs are likely worn. Also note the agitator model (imprinted on the plastic) to match the replacement kit.
Frequently Asked Questions
Can I replace the agitator dogs myself?
Yes. Replacing agitator dogs is a DIY job for most people with basic tools: a socket set (often 7/16" or 1/2"), pliers, and a rubber mallet or block of wood to help remove the agitator. Always unplug the washer or shut off power first and refer to your model’s service sheet for any model‑specific steps.
How long does installing an agitator dog kit take?
On most top‑load washers it takes about 20–45 minutes from start to finish. If the agitator is corroded or frozen on the splines, removal can take longer and may require penetrating oil or additional leverage.
