I've successfully detached the sprayer arm from the "hub" that it was attachd to.

How can I disassemble the rest of it? I've got gunk clogging the holes of the sprayer arm, so want to get it out of there to take it apart and clean it out. Further, I'd like to check everything under the hub to be sure no junk is stuck in there.

Thanks!

Rick,
I moved your question over here from the plumbing page.. Regards, Tom)

Thanks, Tom.

In the meantime I figgered it out!

You can barely see a disk/washer looking thing surrounding the center spray hole. With vice grips I was able to unscrew it and remove the sprayer arm... which has TONS of crap in it. Boy, this dishwasher should work twice as well now!
