Tip & How-To about Dishwashers
Sometimes my dishwasher fails to dispense the soap during the wash cycle. The door just doesn't open. Usually when this happens a small white plastic clip that attaches to the front of the lower basket is found lying in the bottom of the unit. After Macmarkus, on this site, convinced me that this piece did not control the dispenser, it occurred to me (and to him at the same time, I think) that sometimes I would replace the clip onto the rack, but misplaced it so that it blocked the door during the cycle.
Why this clip came off in the first place is unknown. What its purpose is/was is unknown. Whirlpool has discontinued it. And good luck finding a diagram with its correct position. By trial and error I found where it belongs eventually. Will mark the correct rung with permanent marker.
Before any one tears their machine apart replacing the entire dispenser mechanism, make sure it's not just a matter of a misplaced piece of plastic causing all your problems. Debbie Wilson (and Macmarkus)

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...
