Question about Whirlpool Dishwashers
Close the soap door and put into diagnostics. most models you can do so by pushing heated dry-normal-heated dry-normal. let it do its test and if the soap door opens during the test cycle, most likely the soap door assembly needs to be changed.

SOURCE: Dishwasher soap dispenser sticks
Mine dishwasher (a Maytag) did this also. At first it was becoming stuck because of the soap. My repair guy cleaned it and I switched to liquid soap and it worked great another 2 years then did it again. That time it was just wore out and had to be replaced. I was told it was no longer available but we found it here http://www.repairclinic.com/and our repair guy installed it. He was amazed because he had even called everywhere.

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.

please try this...
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.
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..
