The Parts select video instructions for this part are pretty much spot on. The grinder assembly broke where it attached to the circulator pump impeller shaft. The screen became totally clogged and thus no water pressure to the diswasher spray arms. The only thing Id add would be to verify the circulator pump impeller is in good shape after removing the old grinder assembly and that you are able to rotate it by hand in case the impeller motor itself is seized or the impeller is jammed. Once the grinder assy was replaced good water pressure and cleans like a champ.
