I had the same problem. The dishwasher would run, and at theend of the cycle there was water still inside the machine. I'm not an applianceexpert, but I just went through some troubleshooting.
Turn the power off, pull the unit out, and disconnect all the hoses. Get some towels because water will start leaking out of the bottom. In my case, I removed all the hoses, including the one that connected to the disposal. I blew through the ends of each hose, and right away I found one hose that was obstructed .This stuff builds up over time, almost like someone's artery, and once clogged, your best bet is to throw it out, and get a new hose. Its a cheap solution, and is usually the cause.
Your problem sounds identical to mine...so see if my video helps, cause I've gotten feedback from others who found it useful.

There is an insert in the sump that that screen clipped to, squeeze that and pull up, and clean it. now stick your hand down in the sump, and pull out whatever it is that is clogging the drain hole.

Very helpful to me also, but I cannot get the plastic liner out of the sump hole, even with squeezing it and pulling with hands and prying with screwdriver. My goal is to get the flat metal screen off the floor of the dishwasher in order to clean the gunk off of it, but the sump liner has a lip that holds down the screen around it.
