Customer Questions and Answers for Lint Filter by Whirlpool

Hello Steve! If you remove the top agitator cap down inside the lint filter/upper agitator should be a bolt, this secures the upper agitator to the lower agitator and holds the two items secure in place. Check around the tub to see if you notice the bolt floating anywhere or if it is missing. The agitator bolt is part number WP358237 if you need it. Hope this helps!
