Dishes are cloudy and have soap residue. Have cleaned upper &lower spray arm often, as good as posible (find holes plugged). water level & temp. seems normal . Water intake screen appears clean

It sounds like you have a faulty float switch. It's cutting off the water inlet before the tub is full.

Most dishwashers dispense the detergent via gravity and the sprayer arms spraying against the soap dispenser once the little door flips open during the wash cycle. Since it sounds like the soap door is opening I would look at the sprayer arms and make sure they are free of food particles or other debris that might be keeping them from rotating and spraying properly. Here are some instructions for performing this check.

Remove the lower dishrack from the unit. Reach into your dishwasher and spin the lower spray arm. Take note of whether or not the arm moves freely or if its movement is restricted. It should not be restricted in its path of motion. Now gently pull up on an end of the spray arm. The spray arm should be free to wobble up and down. Unscrew the arm retaining knob (some of these are left hand threads) and take the arm out for inspection and carefully examine the spray arm seams. If they have split or are damaged, the dishes may not receive the amount of water pressure required to fully clean the dishes or to rotate the arm properly. What’s more, if water is in fact spraying out of the spray arm from its seams, it is possible that it can cause your dishwasher to leak. Make sure there is no debris in any of the holes.



If your dishwasher has a spray tower, pull up on it as far as it will go and then let it fall back down. Again, this movement should not be restricted. It should be a fluid and smooth motion. Also, unscrew the spray tower and examine it for any debris or foreign objects. Remove any that you find.
Gain access to the upper spray arm by removing the upper dishrack. Perform the same tests for the upper spray arm as you just did for the lower spray arm. Keep in mind that the upper spray arm may not wobble as much as the lower spray arm.
On a final note, some dishwasher models have a water tube that meets up with the upper spray arm once the upper dishrack is pushed back. It is a good idea to check to make sure this tube is aligning properly with the upper spray arm and that this has not split or is damaged in any other way.

Check the outlet holes on both spray arms for clogs. If necessary, remove the spray arms, clean out the holes and empty out any debris inside the spray arms. Verify that the upper arm is turning also.

If the machine does not drain completely at the end of the cycle, the pump drain outlet is partially blocked and you are retaining dirty water for the next load.

You may have a chemistry problem - inferior soap, empty rinse agent dispenser, or extremely hard water.

Improper arrangement of the dishes can prevent some from being washed. Make sure no dish blocks the spray to another.

Hello, W/D here.
Check the spray tips on the washing arms for blockage. If the arms are removable, take one off and place it over the sink. Take a paper clip, and bend it into an "L" shape. Use this to rake debris out of the slots near the end of the wash arms, and poke the debris in any of the nozzles back into their hole. Back wash the spray arm over the sink, flushing the residue out of the arms and re-install. For those arms that you can't remove, use the paper clip to rake the ends clean, and poke the debris in the nozzles back in the holes. You will have to check and remove the debris several times with these arms, over several cycles.
I see that you use good soap, and that's good, but consider using less of it. The detergent is abrasive, and can contribute to material on the dishes, most notably on the glassware. We have cut our detergent to about 25% of the recommended amount, and the dishes get cleaned just fine. Try cutting yours about 50% and then adjust up or down from there, depending on your washer's demands and the water quality in your area.
Preheat your water at the sink and run an empty load with two cups of vinegar, and just a sprinkle of detergent. This will help to clean out the sump of your machine.

Hi

If you are noticing that the dishes are not clean, then there are a few things to check for. Check the soap powder if it's kept in a dry environment. Also try replacing the powder with something like a gel or liquid. Next thing to check for is the water pressure and fill valve. Check if the water is filling in and the spray arms are throwing the water with enough pressure. Try and listen to the sound if you hear a proper spraying action sound.

If it seems as a low water pressure then check the fill valve. Now, check if dishwasher is draining the water or not. While the dishwasher is working check whether the dishwasher is draining and there is not much left out water after the cycle is complete. Try cleaning the spray arm with a soft brush. The water temperature plays a major role in cleaning of dishes. The temp should be between 125 and 150 F for dishwasher to clean the dishes. Hope this helps...

Hi,

It sounds like a washability problem. A couple of things to check.

See if the bottom and top spray arms are free turning. Then look closely at the holes to make sure they are not plugged with anything.

The rest of this applies if you have mode KUDG25SH, if you have a different model number on the tag inside the door let me know and ignore the rest here.

You may have a split in the upper spray arm feed tube. If you slide the upper rack out and look under it you will see the spray arm(propeller looking) under and behind there is a vinyl tube also attached to the rack, look that tube over good, if it is broken or cracked you are loosing water pressure that does the washing.

Let me know what you find and I can help more if needed

plugged spray arm holes, pump intake partially blocked, too little water getting in tub cuz screen in fill valve has debri

Check the following to address this issue.


1. No water
Make sure you get water to the dishwasher. Check to see if the water shut-off valve (located under the sink) is open. If you get water to the dishwasher, but there is still no water inside during the fill cycle, the problem might be with a faulty water valve (located at the bottom of the dishwasher, behind the kick panel, on either side), in which case replace the water valve.

2. Not enough water
If there is not enough water, the dishes would not get cleaned. This could be caused by a partially closed water shut-off valve (located under the sink), or a faulty dishwasher water valve (located at the bottom of the dishwasher, behind the kick panel, on either side).

3. Clogged spay arms
There is usually two, sometimes three spray arms in a dishwasher. Make sure there is no debris blocking the holes inside each spray arm.

4. Water temperature is too low
To get the best results, the water has to be at 120 degrees Fahrenheit when entering the dishwasher.

5. Not enough soap
If you only fill one part of the soap cup, try adding soap to both parts.

6. Smoky film on dishes and glasses
This problem occurs due to excessive calcium build up inside the dishwasher. Try cleaning you dishwasher using a dishwasher cleaner.

Remove each arm and inspect the small spray holes for plugging. Use a vacuum in the center hole and poke out each plugged hole. Unless your vacuum allows wet pick-up, make sure the arm is dry first. Try using a capsule type of detergent instead of liquid. You might have to tear down the lower spray arm assembly to the deck to clean the large screen which may be plugged with water/food deposits. Use hot water, detergent and white vinegar to clean the screen. Hope this helps!
