Kqon, looks like your dispenser has a wax motor. I think the first thing you have to do is remove the inner door and inspect the soap dispensor assy. See if any of the moving parts are broken. This wax motor is 120V so you can run a cheater cord to it to see if it works, but be very careful when doing this. It will expand the plunger and open the flap. If the wax motor operates with 120V applied to it then you want to see if you have power coming from the timer. It will be the tan wire # 27 on the timer harness. You also want to make sure the spring and pin are in place on the dispenser flap. Your part number for the wax motor is 902899. Catriver.

SOURCE: soap dispenser does not open during wash cycle

  • Hi,


    please try this...
    imer:
            On mechanical set ups the timer is attached to the detergent cup by an actuator arm. This arm is usually plastic, and if it is broken or otherwise defective then the detergent cup wont be opened. Check the linkage to make sure it is functioning correctly.
    Bi-metal switch or wax motor:
            The bi-metal switch is simply a very precise device that warps, bends, or otherwise deforms when power is supplied to it. The timer operates the bi-metal switch, which inside the dishwasher door. Then the switch is supplied with power and it is working properly, the bi-metal switch deforms away from the latch holding the detergent cup closed and the cup opens dumping the detergent into the washer.
            Some dishwashers have this switch wired through the motor power feed or the heating element. If they are defective then the detergent door will not operate correctly. If the switch itself is defective then you will need to replace it. Another type of mechanism is a wax motor. Wax motors are sealed units filled with wax and found in newer dishwashers and work by heating the wax and forcing up a piston which in turn mechanically opens the detergent cup door. This type of device is also controlled by the timer.
     
    Detergent cup:
            Sometimes the detergent cup becomes built up with old detergent that prevents it from opening correctly. It's usually a simple fix to clean this out. If cleaning it is impossible then you may need to replace the cup assembly.

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.

The soap is not opening during the cycle. We have tried new soap, hot water running before the cycle, little soap, you name it we do it. The only way my dishes get clean is not to shut the soap dispenser.


I have the same problem! Just in the past few days -- UGH! I am highly disappointed in this dishwasher. I read that the failure to release the door is due to soap and hard water build-up. So, I've sprayed the entire soap dispenser unit with vinegar. Hopefully that will help!

If you have a water softener, you should use about half the recommended amount of soap. Never use a wet or paste detergent. As mentioned before, this unit should be under warranty.

It sounds like it may be stuck between cycle steps.(this sometimes happens if the washer is open during a cycle)Try and run it through one full wash cycle as it is.Then check to see if the soap door will close.If not,the lack may be broken

Dishwasher soap dispenser won't open during cycle


I had the same problem with my GE Adora. The dishes were getting cloudy and the soap dispenser would not open. Turns out the hard water deposits were causing the soap dispenser to stick shut. I purchased and used Dishwasher Magic which is a dishwasher cleaner designed to remove limescale, rust and buildup. I used as directed and now my dishes are sparkling and the soap dispenser pops right open.
