If your dishwasher isn't draining this is probably the reason. I took the old pump off to try cleaning it and inspecting and, and while it made noise it just wasn't moving water. I should have taken it further apart for a better analysis but I was just happy to have the dishwasher drain again.

The whole process takes about an hour, assuming you include time to get the tools, drain the dishwasher cup by cup, and aren't familiar with the underside of the dishwasher. It's literally two electrical connections, one worm drive hose clamp, and two spring style hose clamps. I think I was the most frustrated with ONE of the spring style hose clamp that took 5 minutes because I perhaps wasn't using the right pliers.
