Pdemaio,
ngafm at your service

I believe the loud humming you describe is an electronic problem. And is not worth changing parts randomly and spending unnecessary funds in this fashion!
my advice is a hands on experience repair person that does this day in and day out!
Whirl pool units have many variables! and for the price of randomly changing two or three parts you could have a certified tech finished the repair at a lesser cost to you!
Unfortunately i can not be there hands on or I would be happy to do a hands on diagnoses for you.
Bless You ngafm.
Please leave me a good rating, before you sign off the site.
Ps. Let me know the end result and which electronic part was the culprit..
Thank you

I have a whirlpool gu2400 dishwasher. The spring loaded soap dispenser door does not open during the wash cycle to release the soap.


Whirlpool dishwashers use a wax motor or a solinoid to release the door at a specific time during the cycle. So for proper cleaning the soap cup is nessesary . The part isn't that expensive and fairly simple repair.

Dtergent dispencer does not open



Dispenser Lever

If the dispenser is broken and doesn't open or close properly the dispenser lever might need to be replaced.




Detergent Dispenser Cover

If the detergent dispenser cover is broken and the detergent dispenser doesn't work, the dispenser assembly should be replaced.




Wax Motor Actuator

If the dispenser will not release the detergent the actuator connected between the wax motor and the dispenser might be broken. Check the wax motor actuator and replace it if necessary.




Detergent Container

If the dishwasher dispenser doesn't work the detergent container may need to be replaced.


Dispenser Lid

If the dispenser is broken and doesn't open or close properly the dispenser lid may have to be replaced.




Detergent Dispenser

If the dishwasher dispenser doesn't work the problem is often related to the release mechanism. If the problem is with the dispenser itself, it may be easier to replace the entire dispenser.




Dispenser Door Spring

If the dispenser is broken and doesn't open during the wash cycle the dispenser door spring may have to be replaced.




Dispenser Latch

If the dispenser is broken and doesn't open or close properly the dispenser door latch may have to be replaced.




Dispenser Door Pin

Wax Motor

There is an electrically powered device called a wax motor which opens the detergent dispenser. If the dispenser is broken and will not open to release the detergent, the wax motor might need to be replaced.

Enter your model number to see parts for your dishwasher.


Bi-Metal

If the dishwasher dispenser doesn't work the bi-metal actuator might be burned out or defective. The bi-metal is a simple metal loop which acts as a latch for the dispenser door. As electricity is applied to the metal loop, the loop deforms and bends away from the latch, releasing it. If the bi-metal is burned out it won't deform or release the detergent door.

Enter your model number to see parts for your dishwasher.


Dispenser Slide

If the dispenser is broken and doesn't open or close properly the dispenser slide may need to be replaced.

Enter your model number to see parts for your dishwasher.


Dispenser Repair Kit

If the dispenser is broken this dispenser kit may need to be replaced.

Enter your model number to see parts for your dishwasher.

Main Control Board


The main control board provides power to nearly every component of the dishwasher including the detergent dispenser. If the dispenser will not actuate the main control board might be defective. You should first check for more common parts. Many times control boards are replaced unnecessarily because the problem was not diagnosed properly.

hi friend,
step 1
Remove any large food deposits from the dishes to prevent damaging the dishwasher.
  • Step 2 Load the upper rack of the dishwasher with smaller items, such as glasses, cups and cookware lids. The items must be inserted face down, with the soiled side of each item facing toward the bottom of the dishwasher. Some dishwasher models feature clips, which can be used to secure lightweight items to the tines of the upper rack. The clips work like clothesline pins, and can be moved from one tine to another.
  • Step 3 Load the lower rack of the dishwasher with heavier items, such as plates, bowls and pans. Insert the items between the tines of the rack with the soiled side of each item facing toward the center of the dishwasher.
  • Step 4 Load the silverware basket. The silverware should be inserted into the basket with some items facing up and some facing down to ensure the items do not fit together, which would prevent the dishwasher from being able to clean all surfaces. Knives should be inserted blade down, so they can be inserted and removed from the dishwasher with the handle to avoid injury.
  • Step 5 Add detergent to the dishwasher, and then close the dishwasher's door. Note that the dishwasher has two detergent sections. One dispenser, called the main wash section, has a lid. Open the main wash section's lid by pressing down on the cover latch located next to the section. Fill the main wash section with 3 tbsp. of automatic dishwasher powdered detergent, then close the lid until it snaps into place. The other detergent section is the prewash section. It does not have a lid, because the detergent within the section empties into the dishwasher when the door is closed. Fill the prewash section with 2 tbsp. of automatic dishwasher powdered detergent. Close the dishwasher's door until it clicks into place.
  • Step 6 Prime the dishwasher by turning the kitchen sink's faucet on until it produces hot water. This will ensure the dishwasher has an immediate supply of hot water.
  • Step 7 Start the dishwasher by choosing and pressing the appropriate wash-cycle button, located on the front of the dishwasher's door. Cycle selections include "POTS --N- PANS," "HEAVY" for heavily soiled items, "NORMAL" for standard washing, "CRYSTAL/CHINA" for delicate items, "LOW ENERGY" for lightly soiled items and "RINSE ONLY" for items that will not be washed immediately.

    Detergent door does not open, it completes cycle without using the detergent


      Hi,

    1. The most common problem with the detergent doors on KitchenAid dishwashers is that they either don't open during the cycle or open only halfway. Before looking into more complicated repairs, make sure that the door is able to open. Check the seal around the door and the door latch for soap- and food-related gunk, and scrub it off if present. Sometimes this can keep the detergent door from operating properly. Consider switching detergents, as some liquids and pouch-style dish detergents can gum up the detergent dispensers. Also, make sure that there is nothing blocking the detergent door when the dishwashermag-glass_10x10.gif is loaded. Because of the location of the detergent door, a large item such as a cookie sheet or a pan can prevent the door from opening. Run the dishwasher through a cycle without anything placed in front of the detergent dispenser and see if that solves the problem.
    2. Broken Timer
    3. KitchenAid dishwashersmag-glass_10x10.gif rely on an internal timer to complete the wash cycle properly. When this timer malfunctions, certain steps in the wash process (such as the release of soap from the detergent dispenser) can be interrupted. If the dishwasher detergent door is either not opening or appears to be opening late in the cycle, this is likely the mechanical culprit. A broken timer isn't something that's simple to replace without knowledge of dishwasher repair, so it's best to consult a professional if you suspect that this is the problem.
    4. Malfunctioning Door Components
    5. For the detergent door to function properly, all of its mechanical components must be in working order. Older dishwashers' detergent doors rely on a spring-loaded hinge to pop all the way open when the timer gives the signal. If the door doesn't swing all the way open instantly when it's manually released, the spring may need to be replaced for the dispenser to operate properly. If the particular model is newer and does not rely on a spring to open the door, chances are it either uses a wax motor or a bi-metal switch to release the detergent door at the appropriate time. If either of these components is dying, that can mean that the detergent dispenser will not operate properly.

    Low detergent light does not come on indicating the GE profile dishwasher is out of detergent.


    It is probably because your Smart Dispenser is full of water and there may be a clog of some type in the pump. Try purging your Smart Dispenser and see if it fixes the problem!! It fixed ours!!

    How to Purge Smart Dispenser

    The purge routine operates the bulk dispenser pump continuously to drain the bulk dispenser tank when an incorrect liquid was poured in the tank. The process consists of setting up the dishwasher to run the purge mode, running the purge mode and then cleaning up the purged detergent.

    Follow these steps carefully to have a successful purge run.

    For Top Control Models:
    1. Make sure Pre-wash, Added Heat and Heated Dry LEDs are off.
    2. Press Heated Dry and Down Arrow buttons together for 3 seconds. All LEDs will illuminate.
    3. Press Added Heat and Up Arrow buttons together for 3 seconds. The Anti-bacteria LED will illuminate
    4. Press Start button one time
    5. Select Normal and make sure Pre-wash, Added Heat and Heated Dry LEDs are off.
    6. Press Start button one more time and dishwasher will run a complete cycle without the main motor running. Cycle is complete when the Clean light illuminates. This should take approximately 60 minutes.
    7. Open door and wipe up excess detergent from the door and tub
    8. Flush remaining detergent off by pouring water on the door and tub where there is detergent residue.
    9. Remove SmartDispenser cap and fill tank with water and then replace cap.
    10. Repeat Steps 1 through 9 one time.
    11. Then, repeat Steps 1 through 6. When the Clean LED illuminates, the system is purged and ready to be refilled with the correct detergent.
    Front Mount Controls (same as above except for the changes in the two below steps):

    2. Press Heated Dry and Cookware together for 3 seconds. All LEDs illuminate.

    3. Press Added Heat and Cookware together for 3 seconds. The Anti-bacterial LED illuminates.

    The place where u place the soap won't let all the soap out why


    hello. i can help you.
    When the detergent cup doesn't open, check these:

    Timer
    Bi-metal switch or wax motor
    Detergent cup, itself
    Timer On many dishwashers, a plastic actuator arm mechanically links the timer to the detergent cup. When the timer reaches the proper time in the cycle, the timer activates a lever that opens the detergent cup. If the linkage is broken or defective, the cup stays closed after you've closed it. Check the link and repair or replace it, as necessary.

    Bi-metal switch or wax motor A bi-metal switch is a simple electrical device that deforms when electricity is applied to it. The degree of this deformation can be engineered to concise standards.

    The timer energizes the bi-metal switch inside your dishwasher door--directly behind the detergent cup--when the detergent cup should open. When energized, the bi-metal switch deforms away from the detergent cup latch, which opens the detergent cup. If the bi-metal switch is defective, it may not deform enough to open the cup. If that happens, you need to replace it.

    On some dishwashers, the bimetal switch is wired through the heating element or motor circuit. If the element is broken (or open), or if the motor is drawing low current because of a low-fill situation, the bi-metal switch doesn't open properly.

    Newer dishwasher models use a wax motor instead of a bi-metal switch. It's a sealed unit with wax that heats up and pushes a piston through to open the door. The wax motor, controlled by the timer, mechanically opens the door.

    Detergent cup, itself The detergent cup itself can become clogged with old dried detergent that prevents it from opening. Sometimes just cleaning the cup takes care of the problem. If not, you probably need to replace the entire cup assembly

    The cycles times are too long If your dishwasher's cycle times are too long, check these:

    Water pre-heating
    Cycle not completing
    Water pre-heating Your dishwasher may pre-heat the water. If so, and if the water entering the dishwasher is cool, the heater may take up to half an hour to heat the water.

    To avoid the wait, increase the incoming water temperature before turning on the dishwasher. Do that by running the kitchen sink faucet until the water runs hot. Or increase the temperature of the hot water to the entire house at the hot water heater.

    Warning! To lessen the risk of scalding, don't set the hot water heater temperature higher than 120 degrees Fahrenheit.

    Cycle not completing See "The cycle doesn't complete" section.
