I wrote to the seller. The racks do not show signs of rust. The wash arm is the 4 way Hydrosweep and the control panel is just a dial on top. Of course, we do not know the condition of the control panel or the inside of the machine. Since the tank is porcelain, I would guess that the stuff that looks like rust is just dirt. I am grateful for the answers to my questions. I would have gone to Scranton if it had the big blue wash arm, because this would have been the model that combined the old pump with the detergent cup and the cycle with the prewash. They are pretty rare. On the other hand, the machines like this with the front half of the upper rack that lifts with the lid do not have the loading flexibility & capacity of the KD2P, nor do they have the double wall tank.
