NOTE: Sold individually. This door spring is four and a half inches long. It is used for some dishwashers. These springs tend to wear out at the same rate, so you should replace both of your dishwashe...
First I noticed that the old gasket had disintergrated along the bottom. Next I removed the the gasket being careful to observe how it was installed. There are these notched areas of the gasket that belong in the lower corners. I think the notches are designed to help hold the gasket in place and make the gasket bend around the corner. The gasket made closing the door very hard at first but after one wash cycle the fit became much more comfortable. The heat probably made the gasket more pliable. Problem solved.
My door spring had broken and I was going to leave it until the door gasket failed and started leaking. After removing the parts, I got on-line and order what I needed. I found everything easier than I thought. I got the parts a few days later and put the gasket in first. Looking at it, you'll find theres slotted ribs at both ends. Those areas go in the bottom corners because of the "S" curve. Simply push in and voila, you're done. At first the door will be firm to shut, but gets better- NO LEAKS! As far as the door spring...you don't have to remove the whole dishwasher. Simply unscrew the bottom plate under the door and reach in, rehook. Piece of cake. This site is wonderful. All the parts and easy to use.
We removed the bottom access panel, and were able to remove the broken spring. As others have suggested, we ordered two new springs, so we could replace them both at the same time. Unlike others, we didn't have to move the dishwasher out a few inches to access the springs. An easier repair than it might have been!
