I have a problem with my dishwasher and I'm not sure where to look for the problem. The dishwasher runs normally and it drains properly EXCEPT for the finally cycle. Then it leave clear clean water about two inches deep in the bottom of the dishwasher. The pump is working because I can hear and see the water moving through the drain hose into the Disposal. I've looked online but from what I've been able to find NO Where can I find anything stating this model has a Check Valve or Float, if anyone knows differently please let me known as I have no idea what is causing this issue.
