Soap dipenser My whirlpool built-in dishwasher model DU930PWPB0 serial # FR4104078. The door to the soap dispenser will not open. I have been washing the dishes with the door open all the time. When I close it(door) it won't pop open when it should. to dispense the soap in the wash cycle.

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.

Hi,
There are three common problems that cause the Soap Dispenser or Cup not toopen. I have a tip that will explain these problems in detail....

I have the same dishwasher, have for about 2 years. It took me about a month to figure this out... But, you cannot run it with the flatware rack hanging on the bottom dish rack, you have to move it to hang on the door and you cannot have anything in the compartment under the soap dispenser that is tall enough to block it from opening. Annoying design for sure!

Does the washer heat the water during the hot cycle. If it does, your soap dispenser module in the door is faulty. To install, you need to pull power plug out first,then sit on a chair in front of the door and then open the door towards yourself. Once open unscrew those screws along the perimeter of the door to enable you to remove outer panel. Once off, you can view how to remove soap dispenser. If water does not get hot, check the heater element and/or the reset (over temperature switch). Note, top rotator must move freely as well to allow hot water dispersion which on some occasions activates the soap dish. On other occasions it uses a solenoid switch.

Hi


Many dishwashers (but not all) use a BI-metal strip that heats up once poweris applied to it. The BI-metal strip bends and allows the soap door spring toopen up the dispenser. This bi-metal strip is not given full 120 volts power,the timer "shunts" the power through either the heating element (most common ) or the motor and this gives the bi-metal strip lower than fullpower to work and open. Most often the bi-metal strip has lost its ability tobend properly and needs to be replaced. Older GE dishwashers used a mechanicalarm driven by the timer to open the dispenser = no electrical bi-metals.

Newer Frigidaire dishwashers and many newer Whirlpool dishwashers use a wax motor to open the soap dispenser. The plunger insidethe wax motor slowly moves and pushes the plunger and door open. And, if thiswax motor doesn’t receive 120 volts, then it’ll not work.

This will help you --

I had the same problem once. Make sure nothing is stacked in front of the soap dispenser when you close the door. Slowly close the door and follow the soap dispenser to make sure it has enough clearance to open.
Let me know how it goes.

Symptoms:
Dispenser lid is open. Caked powder at (what would be during normal operation) bottom edge of soap dispenser or caked powder fallen onto dishes or dishwasher bottom. There may be loose powder in rest of dispenser or spilled down inside door or onto dishes underneath dispenser.

Solution:
Keep the area around the soap dispenser lid clear when loading the top tray.

Explanation:
The soap dispenser needs to swing open during the wash cycle. In many dishwashers the top tray has an indentation as wide as the lid of the dispenser. This allows the top tray to be as large deep as possible while still allowing space for the dispenser lid to open. People often pack their dishwasher with things overhanging this gap.

During the wash cycle the catch will release but the overhanging cutlery or crockery prevents the lid from opening all but a few degrees. Some water will splash in but not enough to wash out the soap powder. The soap powder at the bottom of the dispenser will then cake.

When the front door is opened the spring loaded lid, which is partly open, will of course swing fully open and you'll be convinced that the lid opened normally during operation. If this is the problem then if you're very careful and open the door very slowly you can actually hear the lid flip open. Also, depending on when the lid opens, how far it opened during operation and how fast you open the door you may find soap powder spilled down to cover the dishes at the front or down the inside of the door. This happens when you first open the door and obviously there couldn't be loose powder there if the powder had emerged while there was water washing around. Seeing the lid open as you open the door is a lot harder but can be done on some machines.

you will have to check the wax motor that opens the door on the dispenser it is on the inside door panel it is most likely bad

both have a wax motor on them that needs to be replaced you just remove the panel and replace the wax motor is what its called
