Over the past few months, our dishwasher has not been cleaning well.It is aprox 3 yrs old. I use cascade detergent, a rinse aide and ultimate scrub cycle. I also pre-rinse everything. The dishes come out w/soap residue, dried on food particles and water spots. I end up handwashing about half of what comes out. Some dishes look worse than when I put them in. We are ready to toss it. Help please!!!!

Re: not washing well
First of all please check the Water temperature by using a thermometer inside the dishwasher to measure the water temp. It should be as close to 125 degree F to 140 degree F as possible. Now try using the temperature boost feature if your dishwasher is equipped with this cycle feature and check if this will help your wash ability issues.
Now check the Powder soap by making sure that you store your soap in a dry environment and it is not stale and clumping together. Possibly try a different detergent like a liquid or gel. Also, make sure the dishes are loaded properly, or dishwasher is not overloaded.
To check the proper filling dishwasher will fill with water up to and around the heating element. If water is more below the heating element, you may have low water pressure or a problem with the fill valve. Try & listen if it sounds like it is spraying the water around with enough pressure.
For low water pressure, try to clean the screen at the entrance of the fill valve, sometimes the fill valve can fail and not allow the proper water into the dishwasher and may need to be replaced. And, check the spray arm and pump cover for splits or leaks
Low water fills are a very common trouble maker with today's dishwasher.

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!
Make sure you are running hot water to your dishwasher every time you run it. Then make sure you are using rinse aid. Then make sure you are using a quality detergent like cascade. If all that is good I would run some dishwasher magic through the machine to clean it out.
I have a Whirlpool Gold dishwasher and had the same trouble. I found the solution. Fill the detergent dispenser to the top with Cascade Complete liquid gel - it is in a green bottle, then put a half a cup of white vinegar in the bottom of the tub before you start the dishwasher. I have tried them all and Cascade Complete Gel works best. Don't use powder. It really builds-up on my dishes and only the gel keeps the film off my dishes.
I also add Jet Dry in the rinse-aid dispenser but I have a friend who use vinegar in that too. The dishes come out sparkling clean with no film or white build-up. If they still are filmy after three washes using this method, then you may have some build-up in the dishwasher and you can put a cup or two of white vinegar in the bottom - with no detergent or dishes and wash and rinse well. That helps get rid of build-up.
If the glasses are spotty from hard water try a rinse aid like Jet Dry. If they are actually dirty, depending on the brand of DW you may need to rinse them better before putting them in the DW. Not all brands are cerated equally, some do work better then others
Check the following: 1. Is the overfill protection float able to move up and down freely? Press down to release. 2. Be sure the water supply is turned on to the dishwasher.
3. Check for suds in the dishwasher. If foam or suds are detected by the dishwasher sensing system, the dishwasher may not operate properly or may not fill with water. Suds can come from: 1. Using the incorrect type of detergent, such as laundry detergent, hand soap, or dish detergent for hand washing dishes. 2. Forgetting to replace the rinse aid dispenser cap after filling (or refilling) the rinse aid, or spilling rinse aid into the tub (rinse aid causes suds to occur). 3. Using an excessive amount of dishwasher detergent.
its a lime build up from the quality of your water.goto home depot/lowes or a supermarket and buy clr (calcium lime rust) remover.pour a cup in the dishwasher and run a full cycle.this should do the trick.
