Dishwasher racks

The motor in a dishwasher is normally cast Ali housing with a nice 'Copper on steel' winding in it.
The pumps another part with Copper wiring, normally 50 - 75grams and the two water inlet solenoids are 25 grams Copper each. They are both easy 'pick n pop' sources of Copper.
To get the Copper out of the solienoids, insert a screwdriver blade into each end and snap the plastic housing in 1/2, then pull opne end out and wind the Copper onto something. I can do 2 or 3 at the same time.

The stainless steel spray arms wear on their wear surface, there should be a Tefon washer there too.
5 out of 10 dishwasher are dumped because of that. They wear thru and the arm drops and suddenly the washer will not spray and clean the dishes.

Its a easy fix, just remove it and replace it. Easy to find out this problem, just grab the arm and wiggle it, if it moves up and down a lot, its worn thru.

I have found stainless steel dishwashers to be thing most likely to slice you. So I grab these bits and dump the rest.
Wear gloves when working with these, and arm/wrist protection.

A good many of the dishwashers I pick up have aluminum windings instead of copper on the motors, which makes them not worth messing with.
