If it is a cheaper brand/model of dishwasher, you may have to rinse the dishes, especially if they have been sitting for a while. While there are dishwasher who are powerful enough to clean even crust off the dishes, most need to have the dishes rinsed off even just with cold water right after use....If you do not use alot of dishes per day and let the washer build up dishes after a few days then I would recommend a warm/hot water rinse even with a dish sponge and some soap. While some may think that this defeats the purpose of using a dishwasher, remember that a dishwasher is more sanitary that using a dish rag or sponge that had the opportunity to build up bacteria and other gunk over a period of time ;-)

Instructions Things You'll Need:

• Vinegar or lemon juice
• Gel dishwasher detergent

1. dishwashers have a rinse aid dispenser. If your dishwasher has this dispenser, fill it up periodically and it will release the appropriate amount of rinse aid automatically at the right time during the wash cycle. This will help your dishes rinse more cleanly.
2. Rinse aid in solid form
   Some older dishwashers or basic models do not have an automatic rinse aid dispenser. In this case, you can buy rinse aid in solid form that attaches to your dishwasher rack. Solid rinse aid can be hard to find in stores because it is not commonly used, but it can be purchased online.
   
3. Vinegar or lemon juice
   Appliance repairmen will tell you that one of the common problems they see with dishwashers is the buildup of excess detergent. If there is too much detergent in your dishwasher, your dishes will not rinse cleanly, no matter how good the dishwasher is or how much rinse aid you use. To clean the excess detergent that has built up inside your dishwasher, put 3 tablespoons of vinegar or lemon juice (concentrate is fine) in the empty dishwasher and run the dishwasher through a complete cycle with no dishes. Do this twice, for two complete cycles of the empty dishwasher with only vinegar or lemon juice added. The acid in the vinegar or lemon juice will break up the detergent that has built up in your dishwasher's interior.
   
   After you have cleaned the detergent buildup from the inside of your dishwasher, follow the steps below to keep the buildup from happening again and to help your dishes rinse cleanly and prevent residue from accumulating on the dishes.
   
4. Gel dishwasher detergent
   Switch to a liquid or gel dishwasher detergent. Any brand will do.
   
5. Fill one compartment half full Dishwashers will effectively clean dishes with much less detergent than manufacturers often recommend. The bleach in the detergent, combined with the extremely hot water used in the dishwasher wash cycle, will clean and sanitize your dishes completely, even in small amounts, and using less detergent helps prevent buildup and residue from accumulating on your clean dishes.
   
   Fill only one detergent compartment(the one that snaps closed) half full with gel detergent. Snap the opening closed and run your dishwasher as you normally would. Your dishes will come out sparkling clean with no buildup or residue, plus you'll save money by using less detergent!
   

Try cleaning the rinse aid with hot water. Clean all the orifices.
Or you can try the two in one soap tablets.

Check all the water jet orfices in the moving arm. Try cleaning without loading the top rack.

If cleans well, mostly the upper rack dishes not arranged properly.

I hope you are using the main wash detergents. Rinse aid is just to remove the stains after the main wash rinse.

Have you run out of Rinse Aid ?
This has a large effect on drying as well as how clean the dishes come out. Rinse aid [breaks up] the water dispersion, so at the end of the final rinse, the water just falls off the dishes, takes the sediment with it. So with the heat of the final rinse, & less water left on the dishes, they dry better.

Make certain you do not use dish soap when rinsing the dishes. Make sure you only use DISHWASHER soap when running the DW.
In fact,there is no need to rinse dishes. Remove visible scraps and put them in the DW. If it is a quality DW it will clean your dishes. Do not crowd the dishes in the DW. Most JennAir DW's are quality. Make sure the top rack can get washing action from the bottom spray arm. No pots or other water stopping utensils on the bottom rack.

Our Bosch does a pretty good job of washing dishes. But we rinse most of the time. Not a hard rinse, but a rinse.

Are both spray bars rotating? You can test by seeing that the bars rotate easily by hand, and also by starting a cycle and opening the door real quick when you hear the spray hit the door.

Make sure the spray bar nozzles are all clear.

Has it ever done a good job of cleaning dishes?

DI you leave a heavy build-up of food on the dishes, and allow it to dry before washing?

Dishwasher seems to cycle through but dishes are still dirty, like there is no water being sprayed?
