My dishwasher makes an irregular whirring noise during every stage of the wash. I've checked various forums and read about impeller pumps, debris in parts, choppers and the GE broken fan problem. I'm prepared to tackle the repair, but I have no documentation on repair other than the diagrams that are posted on various sites. I'm assuming that I'll need to disconnect and pull the dishwasher out and flip it over to access the parts I need to inspect. I would appreciate any input that you experts may have on this subject. I can build a car from the ground up, but this is my first dishwasher project.

I cleaned the debris screen with no change to the sound. I pulled the access panel and there is a small leak under the motor.
