I've been doing some research online about how to repair a dishwasher.
After figuring out that my dishwasher doesn't have a chopper assembly in this thread, I figured I'd repost with my latest findings.

[Make/Model]
Whirlpool WDF510PAYSA Dishwasher

[Symptoms]
Dishwasher sounds like it may be trying to dispense water, but it's a lot quieter then usual.
Perhaps the spray arms aren't spinning due to a lack of water pressure or bad motor or pump.
After a while the cycle will complete, but the dishes come out dirty and the dishwasher detergent isn't properly dispersed.
I don't hear any motor running throughout the entire cycle, but I do hear something running during the draining phase.

[Troubleshooting] I've cleaned the filter at the bottom of the dishwasher. Everything is clean there. I've also removed the lower and uppser spray arm and ran a hose through them.
Water is indeed flowing nicely through them.
I've placed a couple of bowls in the lower rack facing up to see if water will collect in them, but after a full cycle I didn't see any water in the bowls.

Any help would be appreciated!

UPDATE!

I have gone through the trouble of un-installing the dishwasher and turning it on it's side, and I've also removed the pump.
I haven't encountered any thing suspicious that might be causing clogging.

I was playing around with the pump and my multimeter, and I noticed something that might be of interest. Now, keep in mind that I'm not an electronics expert nor do I know a lot about continuity tests other that "beep is good".
I attempted a continuity tests by touching the two end pins of the pump with the multimeter, and I didn't hear a any beeping. The multimeter didn't respond at all. Below is a picture of the circulation pump with the enclosure removed.

The two pins I touched are the ones sticking out on the right.

Does that mean my pump is dead?

Yes, correct, its bad.

Here's the wash motor pump for your model you can order:

Thanks Jake. I'll go ahead and order the pump and replace it. Once I have it installed I'll update the thread.

Thanks again!
