I have taken several dishwashers that are mostly plastic to the scrap yard and they have never turned them down. I always take the motor off and pull the wiring out. Sometimes their will be a small piece of brass for the inlet pipe.



My buddy owns a appliance repair shop and we took a 18ft dual axle landscaping trailer loaded down with about 25 dishwashers. All but a few were all plastic tubs, still got full price for the load. Not a word said.
