Dishes come out feeling gritty. Using Finish doesn't help

Do you pre wash the food off before the main wash?

before loading the dishes rinse it first outside then wash the complete cycle and instead of powder use the liquid one

Use a good quality powder detergent.
Check your incoming water temperature, 120 degrees plus.
Use a rinse aid such as Jet Dry.
Start the DW without soap and no dishes.
Once it starts the wash cycle pour in 1 quart of WHITE vinegar and let it finish the full wash cycle.
Then load up with dishes and powder detergent and run a load.

Kay - Cloudy or gritty dishes are due to hard water deposits. Starting in summer 2010, many states have passed laws that prohibit phosphates in dishwasher detergent. The phosphates were good at removing hard water deposits. After the law changed, detergents don't work very well anymore. So I created a product that solves the problem. It's all-natural, contains no phosphate, and it works great! It's a powder. You add 1-2 tablespoons to each wash cycle and you use a lot less of your normal detergent. So your cost per wash does not increase. See my website at www.CitriClean.net

The problem is hard water. Go to www.dishwasherfilter.com and get their new product. It filters the water and takes out the hard minerals that cause spots and clog dishwashers. It is very affordable and has a money back guarantee.

Try these things in order:

-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?

gritty ? This can be either the poweder or detergent you are using.Cheap HOME BRAND type. Other than that it is possibly hard water buildup where calcium is now being baked on the dishes in the drying mode.
Try using a Dishwaher Cleaning package by FINISH to see if this helps it

use less soap.....excess soap in the rinse cycle will not allow the dishes to rinse properly causing white etching on the glasses and the dishes will have that gritty feeling

Try putting a cup of white vinegar in the empty dishwasher & running it on fast wash. Should eliminate film; do you have hard water where you live? If so lime build up could be the problem.
Hope this helps.Cheers.
