Let me ask you this. Look under the sink, and if the drain hose hooks up to the garbage disposal, does it leave, the disposal on its way to the dishwasher, and go straight down, or does it leave the disposal, and go up about a foot, and then down? That is the way it should be. If you are walking up to the dishwasher after its done, that could be the problem. because all the water might not drain out, and leave some in the dishwasher. The other thing I would like you to check is to fill the dishwasher up with water, and then hit the cancel button twice to make it drain, and look down the sink, where the disposal is and see if it is draining out hard, or real slow. If it is real slow, you could have a partially clogged drain hose. If so, kill the power to the dishwasher, and make sure you have drained the water out before you kill the power, and then unhook the drain hose from the dishwasher, and the garbage disposal, and take it out side and either blow it out with an air hose, or a water hose. Check it out, and let me know. Tom ApplianceEducator.com

Roy, I did a little digging here on my thought process. The drain is clear, the drain is clear, and it drain fine, all through the cycles, except the last one. I have a feeling that it is in the control board. The control board, part # used to be 8528874, and now it is 8564542. This could be an indication of either a change in the board, which is good, or sourced up to be made by some one else. The only other thing that I thought you should do is to time the drain cycle in the begining of the wash cycle, and see if it compares with the same amount of time in the last drain cycle. I do not think it is the pump, because it is told what to do by the board. Let me know what you find. Tom ApplianceEducator.com
