Whirlpool Washer Agitator (22001821)

The Whirlpool Washer Agitator is the central post inside the wash tub that moves clothes through the water during the wash cycle, creating the back-and-forth motion that loosens and removes dirt and debris. It connects directly to the drive system below and uses fins or vanes to push water and laundry in a rotating pattern for effective cleaning.

The Whirlpool Washer Agitator can wear out over time due to cracked plastic, broken drive lugs, stripped splines, or damage from overloading the washer with heavy items. Hard water deposits, repeated stress from large loads, and normal use can all weaken the agitator's structure until it can no longer grip the drive shaft or move clothes properly.

These symptoms can help you decide if your agitator is the source of your washer problem:

- Agitator spins freely in one or both directions without moving clothes

- Visible cracks, breaks, or missing fins on the agitator body

- Clothes come out poorly washed or tangled after a full cycle

- Agitator wobbles, feels loose, or shifts side to side during use

- Grinding or clunking sound coming from the center of the tub during washing

- Agitator does not move at all while the motor and tub are running
