Dishwasher not draining

Dec 30, 2008

-   My Dishwasher was working alright until a couple of days ago. It runs through all the cycles, but at the end when I open it up it still has dirty water in the entire bottom of the machine. It does not over flow during operation. I drained it by unhooking my drain hose and using my Rainbow vac to **** all the water and debris into it's water bowl. I dumped more water into the machine and did it again. it emptied out with no problems. I ran a new cycle last night but it still had water in the bottom this morning. So why is it not draining and is there a sensor or something that maybe is not sensing the water left inside and not draining it all?? -   newmantaray
