Is it white and coudy looking? it could be hard water and there is a new product out at that actually filters the water going into your dishwasher. it reduces minerals and rust and sediments. it worked great for me. its affordable too.

I would suggest calling whirlpool to have a tech come out and look at it. Your appliance is still under warranty if it is under 1 yr old. It will cover parts and labor.

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.

Other People Are Reading

  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.

Soap residue on glasses, dishes & flatware...what can I do..I use Cascade & JetDry

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!

We bought a new dishwasher because we were finding a hardened residue was being left on our dishes, it was ruining our dishes. Although we have a brand new dishwasher this problem is still occurring and...

My best advise is to reduce the amount of detergent to the least amount that you can use, and still get the dishes clean. We do rinse the dishes a bit, as the soft food disposer isn't made to act like a garbage disposer, but rather, to catch incidental food residues. We no longer fill the closed detergent dispenser. We sprinkle about 1/2 of the normal amount (that goes in the open cup) on the inside door and close it up. Our dishes get very clean, with no residue. Also, use a good drying agent as this will help sheet the water off of the dishes. It may take several cycles to see improvements, but you should see improvements nonetheless.

It is leaving an enormous amount of white residue on our dishes and is causing all of our metal dishes to come out dark.

The white residue could be from one of two sources.

Detergent Residue:
Using too much detergent or poor circulation of water can leave a white residue on the dishes. If the residue is easily rinsed off with warm water then it is detergent. Use less soap, especially if you pre-rinse the dishes or have soft water. Use a hi temperature wash to help dissolve the soap better.

Hard water deposits:
See this link where I put together some information on this.

Dish washer \does not rinse good leaves white flim

Some things you can do to try to improve your dishwasher's performance:

1) Make sure your dishwasher rinse agent dispenser has rinse agent in it. The filler is usually close to where you put soap in the dishwasher.,
2) Consider switching brands of dishwasher detergent, if you are experiencing problems. Depending on the water condition in your area, certain brands work better than others. Ask your neighbors what works well for them.
3) try different wash cycle's with your dishwasher. Sometimes the economy cycle doesn't work as well as it should.
