Inside the top half of a standard agitator sits a set of small plastic ratchet inserts called agitator dogs. They let the agitator drive the load in one direction and freewheel on the return stroke. They are made of plastic, they wear, and when they do the agitator starts slipping — you can often hear a rapid clicking as it tries to grip. This accounts for a large share of all top-load agitation failures, and it is one of the least expensive repairs on the machine. It matters enormously that it gets checked first, because the symptom looks dramatic and owners frequently assume the transmission has failed.
On direct-drive machines the same plastic coupling that stops the tub spinning also stops the agitator moving, because both run off the transmission. The tell is that the motor is clearly running and nothing is moving at all — not the agitator, not the tub. It is a sacrificial part doing its job, and an inexpensive fix.
If the agitator will not move at all, the coupler is intact, and the noise underneath the tub has changed, the transmission is a real possibility. This is the expensive end of top-load repair — often $300 to $450, sometimes more — and on an older machine it opens a genuine conversation about whether the repair makes economic sense. An honest technician prices the job against what the machine is worth and says so plainly rather than quoting a gearbox and leaving you to work it out.
High-efficiency top-loaders have no agitator at all. They use a low-profile impeller plate and a gentler wash action, and clothes move much less visibly than in an agitator machine. If yours is an impeller model and you are worried because the load is not being thrashed around, it is probably working exactly as designed. That is not a repair, and you should not be charged for one.
Run a cycle and listen. A motor running with nothing moving points at the coupler or belt; a clicking agitator points at the dogs; complete silence points at something electrical — the lid switch, the timer or the control board. Check the machine is not simply stuck in a soak phase. Beyond listening, the agitator cap and dogs are an accessible repair on many models, and a decent technician will tell you if that is all you need rather than quoting a larger job.
Agitator repairs generally run $80 to $280, with agitator-dog replacement commonly $180 to $260. A motor coupler is typically $100 to $200. A transmission runs $200 to $600, and $300 to $450 on older agitator models. The spread between the cheap fix and the expensive one is wide enough that an accurate diagnosis is worth more than a fast one.
