I bought a new main wash motor/pump and to my very pleasant surprise it came with the whole lower assembly. So with that I bought a new drain pump too, because the bearing it it was a bit sloppy. Now, except for the main circuit board, all main operating parts in the dishwasher are new. The how-to-videos are very helpful. It's not a big job to replace the whole assembly, but took a little patience to get it to set in as it should. After completion, there were no leaks.
