Update: The drain hose was full of water from the elbow that goes into the wall to the pump. I took off the drain hose and the coin catch. The coin catch and the washer tub both had brown sludge in them like they weren't draining. They weren't plugged, but did have a small amount of it in there.
I ran the pump for a second to verify it was spinning and it was but I have no way of knowing if it is pumping effectively.
I will say that the pump was growling much louder than I would have expected a pump to sound.
Is there any way to verify the pump is bad?
