Pulled the dishwasher out and removed the old pump, inspected the old pump and it looked to be in good shape. I installed the new pump after looking at all drain lines. After seeing that the pump was ok I pulled the drain lines from under the kitchen sink and there was the problem, just about every drain pipe under the sink was full of gunk from whatever, cleaned all those pipe lines and the dishwasher is working great again, no more loud noise from the pump, the restricted line had to be causing the problem
