Whirlpool Washer Agitator (WPW10131112) (Replaces WP63377)

The Whirlpool Washer Agitator is the central post inside the wash tub that moves clothes through the water during the wash cycle. It rotates back and forth to create the scrubbing action that loosens dirt and detergent from fabrics, making it one of the most essential moving parts in a top-load commercial washer.

Important Compatibility Note: Part number WPW10131112 is the current manufacturer-approved replacement for the following discontinued part number(s): WP63377. If your appliance documentation or old part uses any of these numbers, this is the correct, updated component for your repair.

The Whirlpool Washer Agitator can wear out over time from heavy commercial use, repeated overloading, or damage to the agitator dogs and drive components that connect it to the motor. Cracks, broken fins, or a stripped drive connection can prevent the agitator from moving properly, leaving clothes poorly washed or tangled at the end of a cycle.

Look for these symptoms to help determine if the agitator needs to be replaced:

- Agitator does not move or oscillate during the wash cycle

- Agitator moves in only one direction instead of back and forth

- Clothes come out poorly washed or unevenly cleaned

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

- Agitator spins loosely or wobbles on the drive shaft

- Loud clunking or skipping noise during the wash cycle

- Agitator feels stripped and does not engage with the drive system
