Standing water after cycle

Easy. I removed the dishwasher and all water from inside. After laying the dishwasher on floor, the valve flapper was installed using a pair of pliers. I then set the unit upright, and removed the rear screen from the inside back of the unit. This part has 4 nut screws, and runs the width of the unit. Under the screen, the Piston and Nut Assembly for Check Value simply unscrewed. When I looked at it, I knew this would do the trick. I simply screwed the new one in, and re-installed the dishwasher. After the first cycle, I smiled thinking of all the $$$ I saved.

Parts Select is great :)
