Cleaning agent not being released as compartment door not opening

The last 2 times a cycle has completed and it's time to unload, I noticed the door holding the dish soap not open. Inside there is the remainder of the soap. Dishes are of course not cleaned properly. Is this a water temperature issue not opening the door or is the door activated by a timer. What would be my course of action. I am fully capable of dealing with the issue but would appreciate some guidance. Thank-you very much! Trevor

Re: Cleaning agent not being released as compartment door...

For verifining the exect reson for your problem, you can start with a very simple test- Place the dish soap on the bottom of the dishwasher and run it for a full cycle. In case dishes will not become claen, your problem is with the water temp. If dishes will become clean properly, the problem is with the detergent door that doesn't opened at time (operated by a wax motor that get its power from the timer).Maybe that by cleaning the detergent cup you will solve the problem. In case it will not -To gain access to the wax motor you should open door assembly-Find the wax motor (close to the detergent dispenser cup)and test with a multi-meter if it get power(following cycle's sequence).If it get power, you should replace the wax motor. If it doesn't get power the problem is with the timer. Good luck !!

Re: Cleaning agent not being released as compartment door...

Trevor, a single wax motor is used to activate the detergent cup cover and rinse aid from the reservoir. You will have to get inside the door. Using a test cord to 120V outlet attach the cord to the terminals of the wax motor. The plunger in the center of the motor should push out within 60 seconds releasing the door. If it doesn't push out you have a bad wax motor. If it does push out your problem would be with the board sending voltage to it. Be xtra carefull when doing this test, you will be working with a live cord. Make sure to have insulated clips on the end of the cord so they hold to the terminals..Hope this solves your problem.

    The water is no draining completely out of the dishwasher, its's a Whirlpool 980 Deries

    If you are handy what you will have to do is unclog it. DO NOT USE DRAIN CLEANER. Pull out the filters, clean out the **** and you are good to go. Once you are done with that run it a couple of times and you should be good.

    I have a Bosch dishwasher model # shx4ap05uc/06 and I want to silence the alarm for when it is done. It goes off every 10 minutes until you open the door


    Yes, you can switch the cycle completion signal off (or raise/lower the volume)

    1. Switch the dishwasher off using the ON/OFF button
    2. Open the door
    3. Switch the dishwasher on again. (One of the wash cycle LEDs will flash.)
    4. Hold the > button in. Continue holding it and press and release the Start/Reset button once, then release the > button.

    "Clean" and one other LED should now be flashing. This indicates that the dishwasher is in the options/settings mode. If they are not flashing, start over at step 1.

    5. Press > repeatedly, until the LEDs for "Clean", "Sanitized" and "Rinse Agent" are all flashing.
    6. Press repeatedly until none of the LEDs are flashing.

    The number of flashing LEDs indicate the volume setting . . .

    0 = Silent
    1 = Volume level 1
    2 = Volume level 2
    3 = Volume level 3

    7. Press the Start/Reset button once to save the setting and exit the options mode
    8. Close the door
    9. Switch the dishwasher off.

    Hope this helps. Please let me know if you need further assistance.

    It began with the dishes on the upper rack not being cleaned. Not the bottom rack is getting less cleaning done and some of the liquid detergent is left in the detergent compartment. I tried doing a...

    Check your spray arms for pluggage at the slots and the nozzles. If you can remove them, do so and backwash them over the sink. Unplug the slots and nozzles with a toothpick or fine wire.
    This should also help with dispensing the detergent, but reduce the amount to the least that you can use while still getting the dishes clean. We have cut our detergent usage to about 25%. Also, try to not place tall items where they can block the water spray to the dispensing compartment.
    Use a good drying agent, and crack the door open when the washer reaches the end of the cycle, as this will help the dishes to continue to dry, and further release the steam, resulting in cleaner dishes.
    The reduction of the detergent, along with the cleaning of the spray arms will help a lot. I should note here though that I've had to re-clean the arms after what I thought was a most thorough cleaning. Once they are really clean, they'll work better for a long time (usually).

    Put dish detergent in rinse agent dispenser by accident

    Hello and welcome to Fixya.

    Aside from physically removing the dispenser assembly ( which would be quite involved and include taking the door panel off ) you should be able to "nuetralize" the dish"soap" by adding as much "white vinegar" as possible into the same location as the soap...the jet dry reservoir.

    In fact you may have to try this several times, but you could also try pouring straight water into the reservoir, but that will take some time since it is "soap" as opposed to detergent, hence needing a lot of water to de-lute it to much of a degree.

    I'd go with the "white vinegar" and repeat that several times through a "rinse & hold" cycle. ( do not add any dishes or it empty )

    You can also add a couple of tablespoons of "vegatable oil" directly into the bottom of the dishwasher and some of your regular "detergent" before starting the "rinse & hold" cycle. This will give the soap something to react with and the "detergent" will also help "neutralize" the soap,,,hopefully breaking it down as a result.

    To answer the second part of your post...

    The effect is going to be oversudsing in the rinse cycle since this is when the jet dry/rinse agent is dispensed in the cycle. So what I'm hoping to accomplish with these suggestion's is to minimize the oversudsing or prevent it all together until the reservoir is "purged" of soap.

    Let me know how you make out. It usually works in the cases I've had...eventually. I've seen plenty as you are not the first nor will you be the last...we all screw up, that's life ;o)

    Good luck.

    The wash cycle runs and runs.

    Most diswashers have a complete cycle that lasts over an hour. The machine fills with about 1.5-2 quarts of water, rinses the dishes for a few minutes, then empties the water, then fills again with new water and rinses for a few more minutes, then empties. This is to get a good bit of the looser gunk off the dishes, and to soften up any other stuff that has dried on there. Then the machine fills a third time, the soap door pops open, and it washes for a much longer time to hopefully dissolve away pretty much anything left on the dishes. Then it empties, and does a rinse the soap off cycle, and usually a final cycle that rinses again with a little bit of rinse agent to help them dry quickly.

    The whole process uses about 2 gallons of water.
