I pressed the drain button and it drained out and refilled over a period of about 12 hours. So I knew that the water inlet valve wasn't closing all the way. First, I looked on the Sears website, which indicated the part was no longer available. Thank goodness I looked further and found the Appliance Parts Pros website, where I quickly found what I needed. I replaced the part and it fixed the problem. One more appliance kept out of the landfill and I only had to spend one tenth of the cost of a new dishwasher.
