amana alw480daw water leaking at outer tub at tub bottom on to lip of tub?

water was leaking out of the bottom of the washer upon fill. After power down and some dissassembly I could see water was leaking around the plastic outer tub bottom and onto the lip of the metal tub bottom and from there it poured over the lip and into the cabinet bottom. Underneath the metal tub bottom it was completely dry. I bailed out most of the water leaving about 4" to see where it would drop to. A day later It is at about 2" Just below the inner tub. My guess is that the leak is a bad seal. Does the remaining water level help determine what seal it is most likely to be? Also any suggestions with agitator removal? I have pulled on it until I turned purple and it's still in place. Also I could not see any cracks or holes in the outer tub.
