Hi, I know it's kind of a silly thing but when loading the machine make sure nothing is jammed against the dispenser preventing it from opening. I've run into that a few times and people looked at me like I had two heads but when I showed up to look at the machine,it was loaded like thanksgiving dinner was just over. If that is not the issue then it's either the dispenser itself that is broken or it's not getting power from the board. Either problem will require getting into the door of the machine and running a test program. I would call a local appliance repair company as these tests require the machine to be powered up and specific tools. Hope that helps.

SOURCE: soap dispenser door doesn't open during cycle of my Maytag dishwasher

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: 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.

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.

    please rate my suggestion..

SOURCE: Dishwasher soap dispenser sticks

Your soap is clotting because there isn't enough water being sprayed around inside.  The water spray washes the soap out of the dish, if all is working well.  My machine had the same problem.  I had sufficient water level, but the spray head wasn't spinning very well.  I found the end-most hole in the spray bar to be plugged.  It is the end hole that provides a jet that makes the head spin.  I cleaned a bunch of debris out of the hole and the mchine started working and cleaning like it was new.  That was quite an axccomplishment since the machine is 15 years old.

What to do if the soap dispenser does not open automatically during wash?


Hi
Dishwashers use Bi-Metal strip to allow the dispenser to open/close. This strip when heat up causes the soap door spring to open up the dispenser. If this strip is not heated doesn't allow the door to open. The strip may not be getting 120V or maybe disconnected. Newer (plastic liner) dishwashers use a wax motor to open the soap dispenser. The plunger inside the wax motor slowly moves and pushes the plunger and door open. And, if this wax motor doesn't receive 120 volts, then it'll not work. Please check the voltage to the wax motor/Bi-metal strip; also inspect the connections to these. Hope this helps...

Model shy66co5uc/14 soap dispenser will not open during wash cycle. I can open it manually, but it does not open in any of the wash cycles.


Most likely the small sping that activates to open the soap dispenser is either broken or missing. You need to get this part from the manufacturer.
