We purchased the complete handle assembly, the water pump, have a extra Oring one did come on the new pump, I had a broken wheel replaced. The repairs were simple enough put dishdetergent on O'ring & baffle than it went all together well. Nice to learn these pumps weep just like a car waterpump, for we have automotive repair experience mostly. The color coding on the handle assembly was quite beneificial it went together nicely also. We needed 2 Torx drivers I believe a T 10 & T 15, used a screw driver to seperate the wire clips on old handle. No more water on floor, no more water in tub basin nice clean dishes again. The door now opens & closes well. Thank you
