Dishwasher does not stop filling and already replaced float switch...PLEASE HELP

I have had this problem with the dishwasher and I found out that that it would be a bad float or float switch. So I went on the net and ordered up a new float and float switch I replaced them both made sure everything was put back together the same way. Didn't work, still have the same problem also if I cut the power off from the breaker it still dosen't stop filling as crazy as that sounds it's true the red light on the control pannel goes out and every thing stops but the water. Any advice would be a major help. Thanks...
