Our dishes come out dirty with particles and residue on them after a full wash cycle - Even if it is a small load with fairly clean dishes. It also seems there are pieces of food left at the bottom of the dishwasher after a large load it washed. I thought there was some type of disposal system to eliminate the debris.

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.
Your screens are plugged with food residue in the bottom of the unit. clean it out. You can use 1 gallon of white vinegar for your wash after you clean the screens. Start your washer to fill with water but after the water starts, open your door and pore all of the gallon in the unit. Let it now run for 4 minutes and stop it by opening the door. Leave the door slightly open for 1 hour. close the door and let the cycle continue for 4 more minutes. open the door and repeat it a couple of more times. Let it sit all night with the vinegar in it and in the morning - close the door and let the cycle continue to the end. This should help soften and clean out the food particles in the unit. You can repeat the process and get a better cleaning then too. All the scale should be off your dishes now.
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.
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
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.
Gel dishwasher detergent
Switch to a liquid or gel dishwasher detergent. Any brand will do.
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!
Load the appliance with dirty dishes, placing soiled pots and pans on the lower rack where they will be subjected to the most vigorous cleaning. Glassware and dishwasher-safe plastics should go on the top rack. It is not necessary to rinse dishes before loading them in the Hotpoint appliance, unless the dishes have been sitting for awhile and the food particles have dried.
Fill the detergent compartment with your preferred brand of dishwashing detergent, and add glass rinse solution to the rinse reservoir on the inside of the door if your model is equipped with one, then close the door to lock in place.
Select the cycle you wish to use and press the button. For pots and pans, use the heavy-duty cycle. Normal wash is fine for dishes and utensils.
Save on your energy bill by running the dishwasher only when it is full and by allowing the dishes to air dry instead of using the heat dry function on the appliance.
-Try to use a name brand powder, rather then a generic. Even a small box. I had similar problems with my LG dishwasher when I tried to save money by buying a generic powder. My dishes did not get clean and white marks were left behind on my stainless steel DW liner and the dishes. When you ad the powder, do not over fill the dispenser. Add less than the full dispenser cup and close it. Place some powder in that shallow square indent on the dispenser lid to help the pre-wash cycle. Also, run the water in the sink until hot water runs immediately before you start the DW.
-If, after using Electrosol or Cascade for 2 - 3 loads and your dishes do not come out clean, then I would run a load of dishes without adding the soap. Start the dishwasher and wait for it to fill and begin to wash. Open the door and add one cup of vinegar (white vinegar is fine.) Feel free to ad another cup after the first wash water drains and the second wash water enters and the DW begins the wash cycle again. Run a load of dirty dishes with the soap and check for good cleaning.
-If the problems continue, it is time to remove the filter assembly by removing the 9 silver phillips screws from the filter assembly. You will also need to remove the lower sprayer arm by pulling straight up and then out. With a flashlight, inspect the sump area that was hidden by the filter assembly, looking for any debris that has jammed into anywhere down there. Watch out for broken glass as you feel around. Reassemble and test with a load of dirty dishes.
The poor drying may be caused by not keeping the rinse aid re-filled. Check that first.
Also, these water and energy conserving dishwashers actually use the "dirt" from the dirty dishes to help clean the dishes during the first two wash cycles. Simply clear the big chunks off the dishes and put the dishes in the DW.
Please report back what you find or if you have more questions. OK?
Recommend that you run another cycle with no DW soap aded, waiting until the dishwasher has filled with hot water and begins to do the first wash cycle. Then add 1/2 cup of bleach to the water and close the door. Allow the cycle to finish. Run it normally with a standard load of dirty dishes. Note: These high efficiency dishwashers count on the "dirt" of the dirty dishes to help wash/clean the dishes. Recommend you not rinse/wash the dishes before you put them in the dishwasher.
Watch for any occurrence of the black dots and repeat the bleach treatment.
www.dishwasherfilter.com has a great product specifically for this problem. it filters the water going into your dishwasher removing the hard minerals that cause this problem. after the first load my dishes looked amazing. it is very affordable and fits right under your sink.
On the quest to save water, dishwashers are very frequently overloaded. On the quest to save detergent, they often don't have enough detergent to wash the residues out of them. Try making your dishwasher run with a full load of detergent, no dishes and a nice amount of bleach in it. Do this once in a while and your dishwasher will eventually work much better. Do be careful about any chlorine fumes.
