WIll need model #. Why are you trying to remove tub ? I'd first look at the support strut rods these are typically what causes the UL Code. The thin Silver rods have been upgraded to the Black rods that are thicker and stiffer. But to answer your question the center cap of agitator comes off then the agitator then there is the cam with either 6 stainless screws or a center nut that comes off counter clockwise to remove.
