My Whirlpool Stylemaster 4214164, top loading washer started banging as it went into rinse. I opened it and the clothes seemed knotted on the agitator. The tub had drained but the clothes were sopping wet. I moved the agitator, it seems to be moving freely in 2 pieces, top and bottom. The tub also seems to move very freely towards the cabinet sides. I am thinking washer dogs.
