How to tell if a washer agitator is broken?

Determining whether a washing machine agitator is broken or worn out involves checking for specific physical symptoms and movement behaviors. The most definitive test is to manually grab the top portion of a dual-action agitator and try turning it by hand: if it spins smoothly and freely in both directions without clicking or locking, the internal plastic drive dogs are completely stripped and broken. You should also visually inspect the agitator fins and base for visible cracks, melted plastic spots caused by friction, or loose wobbling on the central drive shaft. Furthermore, if your washing machine motor and transmission are running smoothly during a wash cycle, but the clothes inside the drum remain completely stationary while the machine operates, the agitator mechanism or its mounting bolt has failed and requires immediate replacement.

You can easily determine if a washing machine agitator is broken by performing a simple manual inspection. Unplug the machine, open the lid, and try turning the top section of a dual-action agitator by hand: it should ratchet and spin freely in only one direction while locking in the other. If the entire agitator spins loosely in both directions, wobbles excessively on its mounting base, or if the motor hums loudly during a wash cycle while the agitator remains completely stationary, the internal drive components are broken.
