Question about Dishwashers

8 Answers

Our Whirlpool KUDP01ILBS2 dishwasher isn't working like it used to. Dishes seem to be getting partially clean, they aren't getting dry at all and it seems they may be being rinsed/washed with dirty water. There is plenty of water in the machine when I interupt the cleaning cycle. I always run the hot water in the sink before I start the dishwasher so the first water into the dishwasher is as hot as possible. Also the sani-rinse light is flashing when the cycle "completes".

    Water levels seem fine when I check the dishwashing cycle while in process.

    Nothing is getting even remotely dry. everything is very wet at teh end of the cycle.

    I did notice the heater element never was warm to teh touch during the cleaning sycle (I checked it 3 times) and there is a discolored section of the heating element itself.

    If it is the heater element, which I'm now inclined to believe it is, how do you detach it from the machine to replace it? Do you simply turn the disk at teh base of the heater element where it goes into the machine counter clockwise??

    THANKS

    well the further we go the less I seem to know about fixing the problem.

    All the settings on teh dishwasher are the same as we have been using for the last 5 years we've owned the machine.

    We are running out the cold water from the water supply line before starting the machine so that the water going into the machine is almost scalding hot, and when I open the machine during the cycles the machine is plenty hot inside; although again the heater element is not any warmer than the water.

    Is it possible the heater element isn't coming on during the cleaning cycles because the water entering the machine is already hot enough?

    There is way too much water left in/on everything to have anything to do with the rinse agent.

    If teh heqater element fails to come on at any time, either during teh wash cycle or during the dry cycle will it shut down the machine until it's reset? Or is it only during the washing cycles that the machine will shut down if the element doesn't come on?

    THANKS again

Heat that is retained in the dishes is largely responsible for drying in this dishwasher. Since plastics do not retain heat very well, they will not dry as well as glasses, ceramics or metal dishes. Rinse aid must be used so that the final rinse water will sheen off of the dishes to accommodate this drying process. The heater element at the bottom of the tub is used to add heat during the drying cycle to aid in this process as well. This model of dishwasher does not have any forced air circulation system. Here are some tips that may help you resolve your drying problem:

  • Make sure that you are using rinse aid. Failure to properly use rinse aid can prevent proper drying. Adjust the amount that is dispensed if necessary. Also, check to make sure that rinse aid level decreases over time indicating that it is being dispensed properly.
  • The NORMAL WASH and POT & PANS cycles heat the final rinse water up to 140 degrees F. Use these cycles to help the drying process.
  • Do not choose the air dry option. This option cuts off the heater element during the drying process. NOTE: The heater element is not turned on during the first 6 minutes of the drying portion of the cycle.
  • Do not overload the dishwasher. Load the dishes to allow for proper water drainage.
This dishwasher has a heater fault detection circuit. If the heater is not working, the control will detect the lack of increase in water temperature. The dishwasher will stop and the CLEAN light will blink seven times repeatedly. The dishwasher would not be able to be used until the problem is corrected and the control is reset.

Look at the drain hose to make sure there is no blockage. sometimes they also will buld up soap scum inside the machines. try dumping a full cup of vinegar into the empty tub and run it thru a wash cycle. sounds simple but it works well

RE: DISHWASHER SELF REPAIR - Whirlpool KUDP01ILBS2 Dishwasher Heating Element

If you feel confident to do your dishwasher repair yourself please click on the following link and view the dishwasher repair video first!
Dishwasher Repair Video @ I suggest you put a piece of cardboard on your floor before pulling your dishwasher out so as not to scratch your floor!

If you follow the safely removing a dishwasher video and have the electric and water disconnected you can easily remove the heating element.

Remove it and call an appliance parts store near you (usually in the phone book yellow pages) and ask if they have the part for your Make & Model then MAKE SURE YOU TAKE THE OLD PART IN WITH YOU to make sure it's a match and then have them test it if they can!

This Should FixYa!

  1. You may have a bad heater element if it is discolored in one area,(This can be tested with a multimeter.)
  2. The water temperature needs to be tested to make sure it is entering the dishwasher at or above 120 degrees.
  3. The light flashing,means the filter is clogged.
If element removal is required,The washer will need to be pulled out and laid on its side or back,There are 2 nuts the hold the element in and you will be able to see them.

    Also, There should be a tech manual behind the lower kick panel under the door.

    There is a diagnostic sequence that will reboot the unit.



    I think yours is as followed,(but check the manual to make sure)

    Sani Rinse, Heated Dry, Sani Rinse, Heated Dry, and the dishwasher should enter diagnostic cycle and once complete,should work perfect if it just needs a reset.

    The element is not used to heat the water,it is only used for the drying cycle.(THE HOT WATER HEATER HEATS THE WATER FOR THE DISH WASHER)



    You can test the element by setting the dishwasher to heat dry and letting it run for about 5 minutes

    Then if the element is hot,It works,If it's not it don't work.

Hi, The blinking lights are an indication of a problem, and with the sani indication and the dishes not drying appears the heating element is bad. This also heats the water to a much higher temperature to provide a better wash. Good Luck to you!

    I read gobi20's response after I had posted and agree with what he said, but I would still suspect the element. I believe you may be fooling the sensor since you run the water till it is hot before it enters the machine. Good Luck!

    Hi, You keep asking the same questions I and other experts have already answered. There is no other magic wand. For long distance troubleshooting the consensus would be a bad element. If you need further help you should agree that your question has been answered concerning this problem and ask for instruction if you decide to attempt to change the element on your own. Best of Luck to you!

Wash the strainer in the kitchen sink with water and a mild household detergent. Use a fairly stiff brush to get all the debris out of the holes and slots in the strainer. Rinse the strainer well and replace it. If part of the strainer lifts out for regular cleaning, check it and clean it -- if necessary -- after each load of dishes is washed.

    If the heating element is not coming on the machine won't reset or stop, the cycle will just get stuck when hot water is needed, as thermostat wont detect right temperature and cycle does not advance.

Top shelf dishes aren't getting clean in my 5 year old Whirlpool dishwasher. Any suggestions?


Hello,

The most likely reason the dishes in the uppper rack of your dishawasher are not getting clean is because the filter on the pump is built up withe debris and the water is havinga tough time circulating through the pump. This tip i wrote will show ya how to clean that filter.

Water not heating up and not drying


Hello

If your dishwasher is not heating properly, troubleshoot the issue. You can often repair this problem and eliminate service fees.

Incoming Water
Most manufacturers recommend that the water coming into your dishwasher be at least 120 degrees Fahrenheit. If the water is too cold, then your dishes don't clean properly. Or the dishwasher must run longer to heat up the water. Test the water temperature by running the hot water on your faucet for about 2 minutes or until it gets really hot. Place a waterproof thermometer under the water. If the water is too cold, increase the water temperature setting on your water heater.

Thermostat
The thermostat is responsible for regulating the water and drying cycle temperature. If this thermostat isn't working, the heating element at the base of the dishwasher tub may not come on. Test this element by selecting the hottest temperature setting. Run the dishwasher on the shortest cycle. Let the dishwasher run for a few minutes, and open it up. If the dishwasher water is not hot or the drying cycle isn't starting, order a new thermostat from a parts dealer since this component is difficult to fix.


Heating Element/Drying Fan

The heating element heats up the water and air. Access this element by removing the bottom rack. It looks like a long black rod. If any part of this component is broken or corroded, you must order a new one. You usually cannot fix this element. The drying fan is located in the main housing of the dishwasher, and it blows air around your dishes to dry them. Check this part by disconnecting the dishwasher from the power supply and opening up the housing. Examine the fan, and see if any dirt or debris is preventing it from moving. Clean it. If the fan won't turn at all or if the motor is burnt out, order a new fan since it's difficult to repair this part.

Additional Concerns

If your dishwasher isn't drying your dishes properly, see if you have selected a heated drying cycle. An air drying cycle doesn't completely dry your dishes. Never overload the dishwasher, as this prevents heat from circulating around your dishes, keeping them from drying properly. Plastic and Teflon dishes don't usually completely dry. You must towel-dry these items.

Dishes don't get clean and are never dry.


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...

My still leaves a lot of water on the dishes themselves. It seems to clean and drain ok but does not seem to dry like it used to.


Be sure that your rinse aid is full. Without the chemicals in the rinse aid the dishes take a lot more to dry.

My dishwasher isnt rinsing clean, it leaves a film on almost everything. It is only about a year old. It is a Whirlpool. I can't find my book.


If your dishes or glassware appear filmy or spotted following a complete wash cycle, adjusting the amount or type of detergent you’re using and adjusting your hot water heater’s water temperature may solve the problem. But before you do either of these, put a rinse additive (such as Jet-Dry) in the rinse dispenser to improve the sheeting action of the water.

Next, you’ll have to determine whether the film is removable or permanently etched. To do this, soak a glass in undiluted white vinegar for about 15 minutes. Or, wash the glass with warm water and concentrated dishwasher detergent or a high-phosphate detergent (such as Glass Magic).

If the film comes off, it is probably caused by hard water minerals, improper amounts of detergent, or unsuitable water temperature.

Permanent etching is often caused by a combination of soft water and excessive heat or detergent. If glassware is permanently etched, there isn’t anything you can do to make it clear again. But you can avoid future etching by taking these steps:

1) Be sure hot water entering the dishwasher is no hotter than 140 degrees F. Don’t use extra-hot settings such as “Power Scrub,” and use the “Energy Saver” dry cycle.

2) Adjust the detergent amount.

3) Don’t pre-rinse your dishes before loading them in the dishwasher. Food particles on the dishes actually help the detergent and drying agents clean better.

A common cause of poor washing results is improper loading—dishes that block or impede the spray arm(s) or prevent the soap dispenser from opening. On the other hand, if your dishwasher has chronic problems with good washing, the problem may not be your dishwasher. A good first step is vary the amount of dishwasher detergent you're using and try switching brands.

Other possibilities: Your home’s water pressure may be too low, your water may be too hard, or the water temperature may not be hot enough.

In order for your dishwasher to fill to the appropriate level, water pressure should be from 20–120 pounds per square inch. If you suspect that your water pressure may be low, turn off all faucets or other users of water (such as washing machines and sprinklers) and then put a half-gallon jug under the kitchen faucet. Turn on the hot water full-blast. If the jug doesn’t fill within 14 seconds, your water pressure may be too low for proper dishwasher operation. Call your city water utility to discuss your options, or avoid drawing water elsewhere in the house or yard during dishwasher cycles.

The right amount of detergent to use depends on how large your load of dishes is and how hard your water is. Hardness is measured in grains of minerals—the more grains per gallon you have, the more detergent you’ll need. If your water has 12 grains or more of hardness, fill both dishwasher soap cups completely with detergent. If that doesn’t work, consider installing a water softener. (For more information, see the article Water Softener Systems.

To check water temperature, hold a meat thermometer under the hot water faucet for two minutes; if it doesn’t register a minimum of 140 degrees F., turn up the temperature dial on your hot water heater. (However, if you have a newer dishwasher that heats the water internally, it isn’t necessary to turn up your hot water heater.)

If your dishwasher has worked fine in the past but suddenly your dishes aren’t clean after the dishwasher completes all cycles, listen to the spray arm(s) spinning inside during the wash cycle. If spinning poorly, wait for the machine to cool down, remove the spray arm(s) by unscrewing the hubcap(s), lifting the arm(s) off, and then cleaning out the spray holes in the spray arm(s) with a stiff piece of wire.

Whirlpool dishwasher QUIET PARTNER II doesn't clean dishes, leaves film


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).

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

**Water temperature Note***

To get the best results, the water has to be at 120 degrees Fahrenheit when entering the dishwasher.

Concerning the Film.

This problem occurs due to excessive calcium build up inside the dishwasher. Try cleaning you dishwasher using a dishwasher cleaner. There are a few out there, Try Dishwasher Magic.
