Re: Dishwasher leaving residue inside unit after wash is...
THere is a no filter on this unit just a strainer which is visible when opening the door.(its located near back on the bottom) You can take it off and check for pieces of trash or things that have made it by. The best idea is to take a few cups of vinegar (white) and put it in the soap dispensing door. Also take a big Glass and leave it upright and fill it with vinegar. Then run a normal load but dont use any other soap. ALso if your unit has a spot use Jet Dry or simliar products they really do help.

Dishwater residue is a fairly common occurrence, and several things can cause it. Even the newest dishwashers may leave residue, and it might have nothing to do with the actual dishwasher function itself. However, there are things you can do to prevent, limit or completely remove dishwasher residue during every washing cycle.
Modern phosphate-free detergents are the main culprits when it comes to detergent residue. After every wash, many leave a slight whitish residue behind. After several washings, the residue becomes caked on and leaves a noticeable white tint to your dishes. Some dishwasher detergent brands are better than others, and either minimize residue or do not leave any. Once residue is present, however, the only way to remove it is by hand scrubbing or scraping.
Hard-water residue comes from non-softened water from your hot water tank. Non-softened water leaves a white tint on dishes, but no amount of scrubbing will remove it. Only by wiping a small patch of the dish with vinegar or lemon juice will you be able to ascertain whether the white residue left is hard water or detergent. The slight acidic action of the vinegar or lemon juice removes hard-water stains, but they have no effect on detergent residue.
If the dishes feel greasy when they come out of the dishwasher freshly washed, you are dealing with a greasy residue. There are two main reasons for this: either the detergent is not an effective grease remover, or the hot water inside of the dishwasher, either from the hot water tank or the dishwasher's heating elements, is not hot enough. Boosting the hot water temperature on the water tank may solve the problem, and a second wash cycle may be needed for the dishes. A preventive measure of running the dishwasher empty with a full load of detergent also removes the residue inside of the dishwasher.
Streaking and Spotting Residue
If you have spotting or streaking on your dishes, that may be a sign you need a rinse agent. Many modern dishwashers recommend a rinse agent to prevent spotting or streaking, and without one, your dishes will never be crystal clear or streak-free. The next time you do a dishwasher load, add a rinse agent. If the dishes come out spot- and streak-free, the problem is solved.
The cloudy residue that is left on your dishes is soap that has not completly broken down.
There are a few solutions to the problem. First off, you want to ensure that you are using the "high temp wash" option. This will boost your water temp during the wash cycle to ensure that all the soap breaks down.
The second thing that you want to do to give your dishwasher a boost, is run the hot water in the sink and make sure it's pipping hot before you start your dishwasher. What this will do is ensure that the water that goes in for the "pre wash" portion of the wash is hot and will improve the wash quality.
In my case the counter mounted breather for the drain tube was being restricted ... finally to the point it would not drain the tub at all. I disassembled the above counter drain assembly and cleaned it out as it wass completely blocked and things work very well again. I would suggest this foirst as it is an easy task and is done 'above the counter'.
I then ran 2 cups of CLR with wash cycle ... no dishes to clean out the rest of the washer as on dissaembly of the internals to diagnose they were and very scummed up with a hard white crusty substance that was completely blocking some of the drain sump performations.
