It's really annoying when the dishwasher does not clean properly. In my case the bottom rack of the dishwasher was cleaning well, but the top rack of the dishwasher was not coming out clean at all. In fact, the top rack was barely getting wet.
When this happens the wash water is not being cycled correctly or completely.
The possible causes are either there is a clog somewhere in the system, or there is a problem with the pump. Fortunately in my case the problem was a clog - easier and cheaper to correct.
The clog can be anywhere in the system path from the pump up to the sprayer at the top of the dishwasher. In my case the clog was at the food chopper down near the pump. It's relatively easy to get to, with a little patience:-) But it helps a lot to know what to expect.
This video features a Kitchen Aid dishwasher Model # KUDS03STWH3.
Even if you have a different model dishwasher this video should help give you an idea of what to expect and how to do things.
While you are going through this process it's a good time to give the dishwasher a good cleaning. A clean dishwasher produces cleaner dishes. Using vinegar in the dishwasher will help to clean out the systems in general, but vinegar alone will not give it the dishwasher the cleaning it may need from time to time. A dishwasher can accumulate a lot of build up grime and just plain gunk from food and hard water. The only way to really clean the dishwasher well is to give the dishwasher a good scrub down. This video shows you how to do that too.
Here is a picture of some of the crud I cleaned out of my dishwasher just today (March 16, 2014). Yes, that is a pick for things like nuts. The rest is pieces of broken plastic from the dishwasher silverware rack, pieces of wrapper, bone fragments from meals, a tooth pick and just junk. I have kids. Do I need to elaborate?
I hope that you find this video helpful.
