SOURCE: Dishes not clean
If your dishwasher is cleaning poorly, check these:
Water-inlet valve Most cleaning problems are caused by the dishwasher not getting enough wash water, so the water-inlet valve is often to blame. This valve is usually at the bottom left or right of the dishwasher, behind the lower access panel. It's the device with the main water line from the house, a rubber tube to the dishwasher, and two wires attached to it.
When a water-inlet valve is defective, you may hear the sound that's usually referred to as "water hammer." If the water-inlet valve is defective, you need to completely replace it.
Dishwasher Water Inlet Valve Replacement
Be sure to read and understand any instructions that come with the new water inlet valve.

Well, if the motor is moving, try adding a half gallon of /hot/ water before you start the cycle (just pour a saucepan full directly into the dishwasher). If that sounds like it is doing a lot more "blasting" than it was before- you probably need a new water inlet valve, or perhaps to take your water inlet valve off and try to clean out the screen. Problem being, you arent getting enough water into the washer before it starts washing.
It is located at the front of the machine behind the panel under the door.. but as a check, make sure that the valve under the sink that sends water to the dishwasher is all the way open, as this can cause the same problem.
If you do decide to remove the valve, be sure to cut the power at the breaker, or unplug the dishwasher, and turn off the water valve under the sink.

there is no filter except the screen in the water inlet valve to keep big pieces of grit in the water from defecting the inlet valve..
i dont know exactly why but it sounds like your unit was not installed with a recommended air gap in the drain or something similar and somehow dirty sink/drain/sewer water is making its way back into the unit and onto your dishes.
often times there is a little rubber check valve/flapper in the drain line either installed in the pump or the drain hose just after the pump to keep foreign material from entering the unit..
other than that it would just be mineral and calcium deposits if you are on well water or chunky city water..
hope this helps,
best of luck,
