You may have a defective "flapper valve". Look at a diagram/parts list. It is a $3 part and the installation is simple. The "flapper valve" serves as a check valve to prevent the drain water from flowing through the spray arms when the DW is emptying to the drain. The drain water has a lot of particulate matter from the dishes. Mine was stuck open with a long strip of hard soap scale. I probably could have reused the existing valve and just cleaned it. I believe the problem was caused by using the cheap DW detergent from Sams Club rather than the more expensive name brand. It had a tendency to build up a hard white crust that wouldn't dissolve. I replaced the flapper valve and cleaned the spray bars, and changed detergents. It cleans like new.

    It took about two years to clean out all of the residue from the cheap DW detergent. The spray bar holes kept getting cloged with a white hard substance which was the cheap DW detergent that had built up in the DW piping. If you're having this problem try changing the DW detergent. The outcome was amaizing for me. I am using Cascade Complete and having no build-up problems. BK

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.

  1. Detergent Residue
    • 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
    • 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.
    Greasy 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 problem is most likely that there is still water residue at the bottom of your machine. If the machine is not fully drained it picks up some of the residue and sprays that onto the dishes during the final rinse, leaving an unhealthy and unsightly film on everything.
Remove the bottom strainers and make sure that there is nothing obstructing the outlet pipe and the pump. If possible back flush through the outlet pipe and try draining the machine again before using it again.

Dishes not coming out clean


Check your hot water supply. It should be at least 125 degrees. Are the dishes spotty or still dirty with old food? Try to pre-rinse your dishes before putting them into the dishwasher. You can also run your hot water until it's nice and hot coming from the sink before turning your dishwasher on. If they're spotty, use less or better quality detergent. My guess is going to be water temperature or pressure.

My dishwasher leaves a cloudy residue on my dishes


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.

Good luck!

White Residue


most likely it is your detergent. palmolive eco is notorious for leaving a white chalky residue on dishes. try this out before calling a service tech: put unclean glasses in the dishwasher and in your soap dish and rinse cycle cup put 1/2 cup of distilled white vinegar. if it cleans (or improves) your dishes, then your detergent is the culprit.

Bosch dishwasher


Although I previously posted with the same problem of a film on the dishes after cleaning, I did find a section in the owner's manual which solved my problem. Lift up the rinse aid cap on the inside door - the factory setting is on "4". The rinse aid works in conjunction with your local water, which has variations in it's hardness or softness. When your dishes are streaky, lower the rinse aid setting to 1 or 2. If your dishes are spotted, raise the rinse aid setting higher.
