I'd like to purchase a Sears Elite dishwasher (Whirlpool) pump and motor assembly (8535150 Whirlpool part). I've found it on this site but wonder how difficult the replacement would be. (I'm quite handy.) It looks to me that after disconnection a hose or two and a few electric connections the unit lifts out from the inside, and would hence seem easy. Although, I can't seem to remove the rotor to have a good look at the pump. Any comments?
