Whirlpool gold push button controls on top of the door, leaks bad on fill up from under the bottom center on fill up, all the water runs out, with it off if I dump about 12 ounces of water in it , it all runs out, I suspect it's a O RING OR BIG WASHER ON THE CENTER SHAFT, I cant find a diagram for it, about 3 years old, maybe a grommet, bushing or something, thanks if you can help, richard
