The gray upper dishrack kit replaces the original dishrack in select dishwashers. It does not come pre-assembled, so you may need to transfer rollers from your old rack if your model is non-adjustable...
Well, when you put the back cover on and screw it down make sure you have nothing touching the white wire leading to the oven light. I did and it blew the push switch when I threw the 220 breaker. Actually, the light was on when I came in the room, but when I pushed the switch on the front panel it sparked in the rear and popped the breaker. Then I saw the short and when I tested the switch it would not click. The install was fine.
