Whirlpool Washer 4-Vane Agitator Base (WP3347288)

The Whirlpool Washer 4-Vane Agitator Base is the lower section of the agitator assembly that sits at the center of the wash tub and moves clothes through the water during the wash cycle. It uses four vanes to create the churning action that lifts and rotates laundry, helping water and detergent work through the load effectively.

The Whirlpool Washer 4-Vane Agitator Base can wear out over time from constant friction against wet laundry, heavy or unbalanced loads, and general use. The vanes and base body can crack, break, or strip at the mounting point, reducing the agitator's ability to grip and move clothes properly through the cycle.

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

- Clothes come out tangled, bunched, or poorly cleaned after a full wash cycle

- Agitator moves weakly, unevenly, or not at all during washing

- One or more vanes are visibly cracked, broken, or missing

- Agitator spins freely in both directions instead of ratcheting as designed

- Base feels loose or wobbles when you move the agitator by hand

- Loud clunking or scraping sounds coming from the center of the tub during the wash cycle
