Dishwasher is leaving dirt in cups and not washing it out

First check your rinse aid make sure you have some in there. I have been told that too much or too little of this can cause problems with etching glass and damaging dinnerware. . I would put a cup in right side up and wash a wash as usual and take the cup out and check that water after. Make sure your using a proper soap, and hot water is getting to your dishwasher. Or has it been full and not really coming out over a long period of time?
Another possibility is it is dirty inside the dishwasher, and not draining?

The dishwasher may need to be cleaned. Place one cup of white vinager in the dishwasher, without any dishes, and let the dishwasher go through a wash cycle.

HELLO.

This is the solution to the cleaning issue.

1. Wipe the microwave inside and out with a soft cloth dampened with a warm, mild detergent solution. Rinse with a soft cloth dampened with plain water. Dry with a soft, dry cloth.

2. Put 2 cups of water into a 4-cup measuring cup. Place the measuring cup in the microwave, then heat on high for 5 minutes to loosen food particles that are stuck to the inside walls. Leave the measuring cup inside the microwave for 1 to 2 minutes, then remove and wipe the interior as in Step 2.

3. Remove the glass turntable and wash it in the sink with mild detergent or in the dishwasher. Handle carefully, as the turntable is breakable.

Thanks.

Hello, Thank You for using FixYa. I will be helping you today.Start by running a bottle of dishwasher magic through it and make sure the drain line is clear.
Thank You and please rate my answer if it was helpful..

It sounds like you need to check the filters and clean them. It’s usually pretty simple to do but makes the dishwasher run like new. I think that it might be obstructed somewhere preventing it from being able to fully rinse the dishes. Is it draining all the water after the cycle has finished?

Hi


Thanks for using FixYa. You’ll need to check down the edge of the door seal, see if there is a lot of "gunk" there, this would cause grey marks on laundry. Try these steps--

You'll have to do a few maintenance washes to clear it out of the tub. Try these steps to remove the dirt, debris and odor from the washer—

1. Set your machine to 60 degree wash.
2. Now add 1/2 a cup of Washing Soda or 4 cups of baking soda Crystals and run the machine with no clothes in it.
3. Your drain will sparkle, and it will remove all the debris, lint & mold growth from the drain pump and drain filter. Also the mold from the door seal will be cleared
4. Add 1 desert spoonful of Washing Soda to every wash... I sprinkle it along the crease in the door seal.
5. Clean the fabric softener cup with a rag first, (bleach will not break up fabric softener as it is introduced in the rinse cycle with the fabric softener.
6. Also check the drain hose, it should not be clogged.

This will clean your machine and get rid of the gritty material in the bottom.

Please do rate the solution and revert for further assistance.


Thanks

Is the filter screen over the drain at the bottom of the dishwasher clogged? Maybe the drain hose is kinked or clogged. If not, check the fitting where the hose connects to see if it maybe clogged. Please rate this advice. Thanks!

There is a product out called the dishwasher filtration system. it filters the water going into your dishwasher reducing the hrad minerals that leave that white residue. it is very affordable and works amazing. it goes right under the sink and is easy to install. go to www.dishwasherfilter.com for more info on it.
