RESIDUE ON DISHES-NOT CLEANING WELL-DETERGENT NOT DISSOLVING-LONG CYCLES

I have had this dishwasher for about a year now--it seems to be getting worse and worse upon use--I have removed it from under the cabinet several times and ran it thru the cycles and all of the water seems to be flowing through the system fine. It seems the more we were using it the longer the cycles were taking. Now we have all of the issues listed--bearely cleaning the dishes, not rinsing well and leaving residue all over dishes and especially silverware and the detergent(no matter which brand I have used-several different kinds--tabs,liquid, powder)doesnt seem to dissolve. I have tried running it through the cycles with a degreaser solution and it seemed to do better for about  or five times after that. I have not been happy with this dishwasher from the beginning and should have returned it. It has never done an excellent job on the dishes but I considered it well enough considering I paid only $198.00 for it on clearance brand new. Guess it wasnt such a good bargain after all. If I had the money I would just ditch this one and get a new one. Any suggestions on what could be going on with this machine?? should I just get used to dishpan hands???

    The dishwasher came with the house with recently purchased, It is a hotpoint, i don't think it is one of the better models. I always have residue on the botton of the glasses and dishes and the utensils look horrible. I tried a cleaning solution to cleanse the machine while empty; followed by washing the dishes and it didn't solve the problem. We have well water and I don't know if it is because the water is very hard or not? Any suggestions would be helpful.

    I have the exact same problems AND feelings. The dishwasher has become a storage area for dirty dishes until I can hand wash them. It might take a little longer to get them clean, but I don't have to worry about, whatever, stuck in the tongs of a fork. I can't find the source of the residue.

    Our dishwasher is leaving almost a sandy residue on some of the dishes.

The first thing to check with any of the newer dishwashers is the water temprature coming into the machine and the amount of water coming in. Since you are having trouble with the detergent dissolving, I expect the water is not hot enough. Many of the detergents require 140 degrees f to dissolve properly.

The incoming water should be 120 degrees minimum, then the dishwasher will heat it up some more. The cooler the water, the longer the cycle will take. It won't advance to the next step until the water reaches a certain temp, depending on the cycle selected and the model of dishwasher.

If the dishwasher has to heat the water too much, it will cause the heat element to fail prematurely.

If your water heater is set to the average 130-135 setting, then you may be able to solve your problem by running the hot water at the sink before turning the dishwasher on. This will get the cold water flushed from the pipes so the washer fills with hot water on the first fill.

Also. start the washer in a cycle, let it fill and start washing. Open the door and see how much water is in the tub. It should come up to the bottom of the heating element.

Post back and let me know what you find out.

    Thanks for rating the answer. Did running the hot water help? How is it washing now? I don't know if we can get you completely satisfied with the machine but I would like to get it working as well as possible to solve your problem. Also, we have found that the detergent gel packs do not always dissolve properly and cause a lot of cleaning issues and clogged pumps.

    Thanks/Mike

Residue on your dishes can be caused by inadequate drainage of the machine. Most new machines are pumping the gray water through 6+ feet of hose to an air gap,(that chrome thing next to your faucet) and then on in to a disposal or right into the sink drain plumbing. The problem is occuring when the pump finishes and then all of the gray water remaining in the 6 feet of hose flows back into the machine!!! So in a nut shell you are never getting all of the dirty water with its associated food particles(which tend to collect in the bottom of the machine due to this feature of gravity ) The ONLY way to fix this problem and get your dish machine to drain everything all of the time is to re-route the drain connection to a point lower than the pump in the bottom of the machine. If you have a basement than you can drain it to a laundry sink downstairs .Having the drain connection lower than the machine will do wounders for your dishes. Keep in mind that you must maintain an air gap for the prevention of the sewer system from potentially backing up into the dishwasher. GOOD LUCK!!!

Run a product called "Dishwasher Magic" once a month. It's citric acid, and it will descale and clean the entire unit. Costs about $4.00.

If you have hard water, adjust the rinse agent setting to the highest it will go, and use a bit less detergent than normal.

Posted on Feb 13, 2010

  • bigclaw May 06, 2011

    If your supermarket doesn't have Dishwasher Magic, you can also try using 2-3 packets of Kool-Aid (no sugar) Lemonade powder.

Model FDB510LCB0, same problem, cleaned out the traps, opened it right up, mine is 6 years old and up to a month ago it was working great. Was concerned that the upper arm wasn't getting water but took out the lower arm, put a glass over it, then the tray with a heavy wrench on it and it works. Have run CLR, vinegar, increased the spot solutions but still no better. The only thing I can figure, Electrosol change it compound to include the "diamond brite" rinse solution and my machine don't like it. I've change soap but no luck - any further ideas.... next stop is a commercial dishwasher. Looks like all the domestic ones are made by the same company, the dials and appearance may be different but its all the same inside.

I had the same issue! I had to rewash everything by hand and even then it just didn't get crystal clear. I was ready to get a new dishwasher, even though ours is 5 years old and should still be okay. I kept trying to clean it with white vinegar and it just didn't work. Then I read about lemi-shine. people swear by it, and now I cam one of them! I just bought some at WalMart today - it's a couple bucks and it is next to the dishwashing detergent. WOW - what a difference. No more white stuff inside my dishwasher or on my glasses. amazing. SO glad I tried it before replacing the dishwasher. Go get some now. It works.

Hmm ... I've had the same problem w/ my Frigidaire dishwasher model FDB510LCB0. Dishes are always a mess w/ a think white residue .... doesn't wash off. I just changed the heating element. As it at the white stuff all over it ... I'm thinking the white stuff was creating from the heating element.

Anyway I'm wondering why the problem started in the first time and I'm wondering if it is not getting enough water. When you say the water should come up to the bottom of the heating element do you mean it should actually be touching it? Mine comes to about a centimeter below the heating element.

The issue is hard water. I hated my dishwasher for this very reason. We have hard water and it appeared that all of the dishes were permanently etched with this white etching. A quick inspection of the interior of the dishwasher revealed a huge buildup of lime and calcium inside the dishwasher itself. I took the dishwasher apart numerous times to little or no relief. Then one day I found Lemony Shine. It has made all the difference in the cleanliness of the dishes. I no longer have that residue build up in the dishwasher as using it started reversing the hard water buildup in the dishwasher itself and the added bonus, the dishes are clean! I use less than 1/8 cup of the product and 1 of the cascade complete or finish tablets/pouches they sell. No vinegar, lemon juice, no rinse aides and no more cycles of limescale remover nor dishwasher magic.

I found the Lemony Shine at a Wal-Mart in the aisle along side the Dishwasher Magic products as well as the detergents. It is well worth the $2 - $3 dollars a bottle and one bottle lasts my large family of 8 about 3-4 weeks.

We're on well water, and according to our plumber we have a water softener. However, even after purchasing a new dishwasher, the glasses come out with a white residue, and the dishwasher's pull-out trays are difficult to pull out, after less than a month. Should I have a professional well water person look at our system, and, if so, what should I have them look for?

Posted on Jan 30, 2010

  • bigclaw May 06, 2011

    White residue could be detergent build up. Try running Lemony-Shine, Dishwaher Magic, or Vinegar or Citric Acid through to clean out dishwasher tub, and then decrease the amount of soap you are using.

  • mr_spork Sep 21, 2011

    If your plumber told you that you have a water softener, but you aren't maintaining it (salt or potassium chloride tablets) then it's not doing anything. I have a water softener too, and I have more or less this same problem with my dishwasher, but I have not put salt in my water softener's salt bin for years, so I know that I have hard water. Locate your water softener, there should either be a big round barrel thing next to it, or a rectangular thing that looks like a tall garbage can - put three or four big bags of salt (they cost about $4.50 ish at Walmart) in there and then pour enough water in to cover the salt. Then just make sure the water softener is plugged in (it has a timer on it that needs electricity) and that it's not bypassed (valve associated with the softener) and you should be all set. This won't take away the buildup you already have, but it will prevent new buildup so if you use a citric acid cleaner you may be able to get rid of the existing buildup and prevent it with a properly maintained water softener.

Hi- I am glad I am not the only one in Washington Phosphorous free detergents became mandatory almost a year ago. That is when I began having problems. 1 a month I run CLR through my dishwasher. If I have glasses to run they are run at this time, I am still looking for better solutions. I am not convinced it's my dishwasher but the drastic change in detergent does not work with well water

Posted on Jan 07, 2010

Citric acid can do wonders - just pick up lemony shine from your local grocery store and use it in your dishwasher with your normal detergent and it will remove the white residue. Place lemony shine in the dishwasher detergent section that has a cover (second wash), and your normal dishwahing detergent in the other cup.

    I just bought a new dishwasher, and have noticed my glasses are really foggy looking. The guy at the appliance store said it's because they've taken the phosphates out of the dish detergents. He mentioned the "Lemony Shine" product and also gave me a box of, Finish Glass Magic, (this product does contain phosphates). I live in AZ and phosphates were not outlawed here, yet. I may try the Lemony Shine since it doesn't contain phosphates.

The problem is hard water and there is a new product out called the dishwasher filtration system. it actually filters the water going into your dishwasher and leaves your dishes spot free. after the first load i was amazed that the white film was gone and my dishes were sparkling. you can get it at www.dishwasherfilter.com.

SOURCE: powder not dissolving drain/inlet light sometimes flashes

I would guess the detergent door is open and the powder comes out so, If water is going in then the pump is not pumping.

Listen for the water to fill then after it stops open the door to make sure it's full of water. If no water or not enough then replace the water valve. If you have water then the pump is not pumping.

Posted on Dec 12, 2008

SOURCE: dishwashing detergent isn't dissolving

Either:

  1. the water does not get into the dishwasher open the dishwasher 3-4 times during cycle, you should see some water at least once, if not - check water valve, water level float and water pressure.
  2. the pump is clogged - there is water, the motor will run but no water is circulated. Check pump filters, check chopper and impeller.
  3. motor in main pump is not working - could be caused by something stuck on the impeller or chopper or could be a problem with the motor itself or control board. Check if line voltage is coming to the motor during wash/rinse cycle.
Good luck,

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

KitchenAid Superba KUDSO1FLSS3 Not Rinsing? No Cleaning at all!


Hi there,

Here are a couple of things that you can try:

If there is hard water residue or film left on the dishes:
Check water hardness.
If the water is hard, use maximum detergent or try pouring 1/4 cup of Dishwasher Magic into the bottom of the dishwasher. I would also recommend using the High Heat option to ensure proper cleaning. To clean the dishwasher, use a cup of vinegar and place it in the upper rack.

Detergent carryover:
Check water hardness.
If it's below 10 grains, use less detergent and the High Heat option.

It is also possible that you may have a problem with the drain loop check valve as it's not sealing. This may cause residue or food to be left on the dishes. For this, I would recommend you have a technician do it, as it requires replacing the entire drain loop.

Let me know if any of this solves the problem.
