Hey Guys, i have a Whirlpool gold quiet partner 3 dishwasher. My problem is it goes through the whole wash cycle w/o opening the soap dispenser. The soap door is clean and springs works great. I did remove the front door and “tested” the wax motor, it has about 250k ohms. Also during washer operation, with my volt meter i am receiving random volts send to wax motor anywhere from 12 to about 25volts. So i assume everything is working except the wax motor?
Just would like your opinion on if this would be the best route to start with.

If you could provide the actual model # I’d be glad to look up the wiring diagram to see what the voltage should be to the wax motor.
Apologize for not providing that. Is there a way to find the model number w/o pulling the dishwasher out from under the counter? I still have the front cover off, i just cant pull the dishwasher out all the way, gets stuck halfway out and all the cords from under the sink are fully extended. Just wanna avoid disconnecting all the tubes.
It should be around the door area or on the frame area where the door closes. Generally they’re going to put it in a area where the consumer can find it. The below may help.

[quote=hosic;123108]Found it, thanks!
Its model # gu2400xtps7
type #5750
thanks again[/quote]
I found a schematic and tech sheet I’ve linked below for you.
From what I’m seeing it doesn’t appear to be a wax motor that opens the soap cup. It looks like a solenoid. There is a wax motor, but it looks like it opens the vent. From what I can tell both of those components are on the 120V side of the board. There is a low voltage side which fires up several components but most of them being sensor related. Hope you’re familiar with looking at a schematic, because the below one has a lot to it. It does give the ohms readings for the components in question. It also gives some basic troubleshooting.
After looking at the parts breakdown it does show a solenoid on the dispenser. Take a look at it, it should have a marking on the side of it showing what the voltage rating for it is. If it’s a 120v coil you can put a test wire on it and see if it snaps closed. You’ll probably have to blow up the drawing in order to read it.
Perfect thanks! Im gonna print it out at work tomorrow cause my screen is way to small to scroll around and try to read it
What i wanted to ask was on the release door for the soap, it connects to what i thought was the wax motor? When the plunger retracts it pushes that door arm forward to open the soap door, you can manually do it. If your thinking a solenoid opens the soap, is what i think is the wax motor something else?

What the parts image shows is a solenoid. There is a wax motor on the product but it shows that coming into play for opening the vent.

The parts breakdown shows the dispenser having a solenoid. The place I see a wax motor being used is on the vent in the door. Below is a picture of the back of the dispenser. The white device on the right hand side is the solenoid.
Hello and thanks for the assistance. I did test the solenoid and it does have the proper Ohms, also did run power to it and it does activate so that parts good. Did test the wires in the circuit and there are no opens in the circuit so the wires are good. Any direction you might recommend to check out next? Thinking i might hook up a meter to the dispensor solenoid and confirm the max volts its getting during its cycle, should it get a complete 120v?
Thanks for the help

Going to have to say “I think so”. Now that you’ve got it opened up, what’s the voltage rating stamped on the solenoid? They are usually marked. If it says 120v on it then yes to your question.
If you’re not getting that to it, then check your wiring back to the board, if it’s good, I’d say you have a board issue. I noticed a triac on the board feeding the dispenser, they sort of act like a “gate valve”. If it’s part of the board then the entire board would need to be replaced.
So i’ll give you a update. Last night after puting everything but the cover together i ran that tech diag program that goes through all the cycles. When it got to the time to test the dispensor system, the solenoid actually worked and i had 120V going to it then once the solenoid retracted(normal postion), volts left. Did a full load on normal and it actually opened the dispensor door. Weird?
