Not cleaning properly

it would be improbable that you put too tall an item on the top rack every time you wash, but it is also impossible to check without a see thru tub. Just make sure there are no tall items and maybe lower the top rack.
Some dishwashers have the top arm on the bottom of the rack and use a connection in the back when the rack is pushed in. If yours does make sure it isn't deformed and not making properly.

Use a magic eraser.
Also there is an excellent product from Home Depot, Krud Kutter.
Also googone, not goof off ( Goof Off is a stronger , more potent chemical and Goo Gone isn't as dangerous but very effective and works great!)
Goo Gone is at almost every store.
If these don't work, let me know.
Thanks and good luck !

see please the next video for your fix it: God bless you

Hi,

I have an older dishwasher also and recently my wife also complained about it not cleaning right... so me being the man I am tried in vain to clean the things... Bought new spray arms online and installed them in minutes...now the thing works like new... However I have also found that if the heating element goes bad then that also can mess things up bad... So I would buy new spray arms, and also check out the heating element to make sure it is working... Here is a tip that will help you with the online buying...

First perform a vinegar cycle wash in the dishwasher. Pour a cup of vinegar into the bottom of the dishwasher. Keep the temperature at the highest setting possible and perform a wash cycle.Then start using a dishwasher most probably that would solve the problem. If this does not solve the problem then there must be some parts worn out or faulty creating the problem.

There are many probable causes of failure .

To clean the dishes the water temperature is essential.It the water is not hot then the dishes will not be cleaned properly.So check the water temperature.

Also check the filter in your dishwasher.Clean the filter if there is accumulation of debris in the filter

If you are in an hard water zone , then try reducing the amount of detergent used and then try cleaning the dishes.

Did you check the tube that carries the water to the spray arm?

A common cause of poor washing is improper loading—dishes block or impede the spray arms or prevent the soap dispenser from opening. On the other hand, if your dishwasher has chronic problems with washing, the problem may not be your dishwasher. Your home's water pressure may be too low, the water may be too hard, you may not be using the right amount of detergent, or the water temperature may not be hot enough

Yes there is the Water Div valve, it diverts the water between the wash arms.

there is a new product out that filters the water going into your dishwasher. it works great and my dishes look fantastic. they use to look dirty with a white film on them. after the first load when i hooked up the dishwasher filter my dishes looked brand new. it is affordable and works everytime. you can get it at www.dishwasherfilter.com.
