Upper dishes not clean on KUDS01FLSS2

Check your water inlet for the right pressure and then the water float valve for the right amount of water in the tub for washing. The tub has to have the right amount of water in it to pump it up to the top. It is also possible that the pump has debris in it that is restricting the flow. Clean out the screens and check the bottom of the washer tub for debris at the pump inlet. Use white vinegar to clean out your washer. Start your washer - open the door and pour in a lot of vinegar. Let it run for a few seconds and stop it. Let the vinegar work on the scale and debris. Start and stop it several times during the day - not completing the wash cycle until in the morning - after it has sat with the vinegar 10 -12 hours.

DISHWASHER NOT CLEANING WELL??
Here are 5 common reasons why not.
Here are Improper Water Temperature
I can tell you from personal experience that water temperature has a direct impact on how well your family's dishwasher operates. If the water entering your dishwasher is not hot enough, your dishes are likely to come out coated with grease and dish detergent residue. As such, you will want to make sure that the temperature of the water inside your dishwasher is somewhere between the range of 120 degrees Fahrenheit and 140 degrees Fahrenheit. If it's not it could be a faulty heating element.
Dirty Pump
Based on my experience, a dirty dishwasher pump will also cause your dishwasher to produce less than stellar results. Therefore, you may want to consider cleaning your dishwasher's pump every six months. In many instances, it is an easy task to complete. In order to clean your dishwasher's pump, you'll most likely have to remove the dishwasher's spray arms. Once the spray arms are removed, you'll want to clean and inspect the pump's impellers, blades and pump guard. I should also mention that there are appliance companies that sell dishwasher pump repair kits should you notice that a part needs to be replaced. A basic dishwasher pump repair kit will tend to cost you $20 to $60 depending on your dishwasher's unique needs.
Dirty Spray Arm
Dirty spray arms may also be to blame. After all, if the spray arms' holes are clogged, the hot water won't be able to reach the dishes properly. A dishwasher's spray arms are very simple to clean. In order to clean them, you will need an old toothbrush and a bread twist tie that has been stripped of its paper. Use the toothbrush's bristles and the wire from the bread twist tie to unclog all the holes.
Broken Dish Detergent Dispenser
A broken dish detergent dispenser is another likely culprit when it comes to dish cleanliness problems. Sometimes the dish detergent dispenser's door will not open or shut properly, which prevents the dishes from getting nice and soapy. The good news is that most dish detergent dispenser problems may be solved relatively inexpensively. The cost of a replacement dish detergent dispenser will vary based on the make and model of your dishwasher. There are also instructional videos online that will help you with the installation of your dishwasher's new detergent dispenser.
Dirty Filter
A filter has an impact on a dishwasher's effectiveness as well. Hence, you will want to inspect your dishwasher's filter for obstructions. The location and type of filter will vary based on your dishwasher's make and model. I would recommend that you check out your dishwasher's operator's manual. It should contain instructions on how to clean your particular unit's filter as well as where you can order a replacement part if need be.

Hello Mike,

What ya want to try is to clean the filter screen on the wash pump and see if that helps to circulate water better resulting in better washability.

Check that the arms spin freely when spun by hand, then check the outlet jets at the trailing end of the arms are not blocked with food particles and other solid matter. This often happens and the arm is unable to turn because the water jet that is supposed to drive the arm does not have the force to rotate it with the result is that the upper dishes do not get enough water and chemicals. .

The problem is hard water. There is a new product out called the dishwasher filtration system. It filters the water before it enters your dishwasher. It works amazing and has a money back guarantee. You will love the way your dishes look after the first load. It is also very affordable (like 70 bucks). Go to www.dishwasherfilter.com to find out more info.

Hello there:
There are 6 areas that could cause this to happen Please follow these simple steps ok
Investigate each of these six areas if your dishwasher is not completely cleaning your dishes:

Water Inlet Valve

A dishwasher's water inlet valve is its most common part to fail. When your dishes are not being fully cleaned, quite often a faulty water inlet valve is to blame. Test your dishwasher's water inlet valve, and if it is no longer functioning as it should, you will have to replace it.

Upper or Lower Spray Arm

Your dishwasher has a lower spray arm. It may also have an upper spray arm at the top of the dishwasher. These spray arms are designed to shoot high pressure, high temperature water at your dishes. It is possible that the holes of the spray arms, where the water comes out, are blocked with debris, affecting wash quality. You should inspect your dishwasher's spray arms regularly. Clean out the spray arms as need be.

Heating Element

Water temperature is a key element in achieving clean dishes. A dishwasher's heating element is not designed to heat the water that enters it. Rather, the heating element is designed to maintain the heat of the water that enters the dishwasher. Its a good idea to run the hot water in your sink for a couple of minutes before you run the dishwasher. Just to make sure the water is nice and hot before it enters the dishwasher. If the water is unable to stay hot, it can adversely affect your dishwasher's cleaning ability.

Filter/Drain Grate

There is a filter in your dishwasher. Its function is to keep large particles of food and foreign objects away from the pump. Many of the newly-manufactured dishwashers have self-cleaning filters, and routine cleaning isn't a concern. However, some other dishw ashers need to have the filter removed and cleaned regularly. If the filter or grate is clogged or blocked with debris, it may interfere with the normal functioning of your dishwasher. Consult your owner's manual for specific directions for removing your dishwasher's filter and cleaning it.

• Find a filter for your dishwasher.

Detergent or Detergent Cup

It could just be that you aren't using enough soap to completely wash your dishes. Your dishwasher may be designed to dispense soap at two different times during the wash cycle. If you don't fill all of the detergent cups, then the diswasher will lose a cleaning cycle. Also, if you use a gel-type detergent, try switching to a powered kind. Powders tend to dissolve better in hot water. And don't buy in bulk. Detergents are most effective in the first two weeks. After that, they decrease in potency.
Alternatively, your dishwasher's detergent cup could be defective in some way. It is possible that it is gunked up full of built up detergent, and a thorough cleaning may be enough to get it working again. If that doesn't do the trick, you probably need to replace the entire detergent cup assembly. If your cup isn't even opening, please see our section My dishwasher detergent cup won't open.

• Find detergent dispenser parts for your dishwasher.

Cycle Selector Switch

Sometimes a dishwasher's cycle selector switch is the reason why dishes are not coming completely clean. Test your selector switch to determine whether or not it has become defective. If it has, replace it.

Check the upper spray arm for debris plugging the spray holes, if clean then pull off lower spray arm and filter screen, and clean and remove any debris found in the sump, check the disposal blades as well. You will need a torx style screwdriver to remove the sump screen on this unit. You can buy a set for under $10 at your local hardware store.

Look in the inside for any screen that would be easily removed, some dishwashers have a self cleaning filter so you may not find it. I have a lot of other tips for you if your dishwasher is not cleaning so check it out.

Penrod, sounds like a circulation problem. Two things to check first. make sure the upper spray arm is not clogged with debris or split. Second is to twist and remove the filter and clear out any debris where the water enters the circulation pump impeller. If something has jammed the impeller, you would have to remove the dishwasher, remove the tank, remove the circulation motor and clean out the impeller...Catriver...post back.
