Dishes not getting clean in a whirlpool dishwasher model # DUB700xy-1

SOURCE: Whirlpool gold dishwasher leaves film on dishes

the problem is hard water i bet. there is a new product out that actually filters the water going into your dishwasher. this i think is awesome becasue who knows whats in the water cleaning the dishes you eat and drink with. my dishes use to be white and spotty and after the first load with the filter they came out spotless. you can get it at www.dishwasherfilter.com. you will be glad you did. oh it goes under the sink and is small and affordable.

The top rack is not cleaning because of low water pressure from the wash motor to the upper spray arm.
Assuming the top spray arms are clear of debris, remove the lower spray arm to access the wash motor. Remove the 4 torx screws and the filter (accumulator assembly). Remove the torx screw and the inlet protector that covers the chopper assembly. Make sure the chopper is not broken (broken chopper will fill with debris and block water flow). While holding the chopper blade, reach inside the "D" shaped opening on top of the motor and spin the wheel/motor by hand in each direction to make sure either the chopper gear or the motor gear that drives the chopper is not broken. Replace the chopper if necessary (part # 8268383). If the motor gear is broken, replace the sump and motor assembly (part # 8535150). Remove any debris from the sump area in the process.
You don't have to shut the power off to the dishwasher because the door will be open, but if you feel more comfortable, do so.
Good luck!

In my experience, you probably have a clog in the spray arm/arms for the top rack. Take the arm(s) out and see if the holes in them are clogged. Rice, plastic wrappers, and glass from dishes that broke in there are the most common culprits I've seen.

We also have a Quiet series 100 and had the same problem, the dishes always came out dingy or with food all over them. My washer is about 5 years old and worked well for about 4 of them but the last year has been doing a poorer and poorer job washing the dishes. I finally broke down and removed the racks and all of the plastic parts from the inside of the washer. Doing this revealed that the groves in the under side of most of the plastic parts was clogged with food and debris. After a good scrubbing with water and a brush then reassembly it worked like a new washer again, cleaning the dishes very well and the best part is it saved us about $700.00 for another washer.
