I can relate to your dilemma. I mean, when it comes down to it, it might be easier and more cost effective to just get a new one. But, if you're anything like me, it pains you to throw something out that is otherwise still perfectly fine, but for one broken piece like the pump or motor. I wish you the best of luck, although, I think more specific advise may be hard to come by. It sounds like a take it apart, clean components, put back together, and pray as you plug it in, type of situation.
