Hi Jordan, I have a top load Hoover A6590 washer which may be similar. At the bottom of the agitator is a plastic sleeve with a rubber flapper valve. You can pull this out with a piece of wire. Underneath is a 12mm bolt, which holds the agitator in. Unfortunately I have not solved the next riddle which is how to release the stainless steel drum from the spline shaft.
