After some research, I found that the sump and pump assembly would address the issue. I could have tried a few other items first, but did not want my dishwasher to be down longer than it was. I ordered and replaced this assembly. I have a Whirlpool gold series that is less than 2 years old as on Jan 2017. I had to reuse the connection to the upper level sprayer tubes as the one that came with did not fit. It was difficult to keep the assembly seated in order to close the 3 clips. It worked and my dishwasher is no longer leaking.
