Re: dispenser door

Remove the outer door panel and check the actuator for the soap dispenser door it is probably broken. You might also check and make sure you don't have an old soap build up inside the soap dispenser. Sometimes old soap builds up and dries inside the dispenser and causes the door to stick. It should be free. Good luck.

Our dishwasher is not dispensing the soap. I have tried using the cubes (stays in wells), tried powder (it turns to a cake of soap) and I have tried liquid but you could see it ran down the door. Some...

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. Dishes are not clean if water is hard or when more detergent is used than needed, try filling detergent cup half way. Try using white vinegar after the wash cycle is complete, run a complete cycle. Also turn down the heat on the hot water fed to the dishwasher. Try using water softener for better results. You can also add vinegar in the final rinse cycle. Make sure that your soap dispenser drawer is opening and closing fine. Hope this helps...

The soap does not fully 'dissolve' after running the unit

I believe this is just a matter of dish placement, and not a matter of anything physically wrong with your unit. The way the unit works is when the "computer" tells to open the door, it releases the latch. That is all it is responsible for doing. After that gravity and the splash of the water jets must take over. So simply just make a visual path where you know water jets can hit that area and you should be alright. IF the powered soap is already caked in the dispenser you will have to manually scrape it out with a wood or plastic stick.

Tablet falls to the bottom of tub but wont disolve

The newer Whirlpool dishwashers have little slots in the top of the soap dispenser to allow water to seep in during the first water fill. This design allows the tablet to begin to dissolve during the first fill then be usefull when the soap door opens. In your case, I would check to see if the soap dish is opening at all. Perhaps one of the racks are not allowing clearance or the soap door itself is sticking closed.

Let the dishwasher fill, drain, and then fill again. Open the door of the dishwasher and see if the soap door is still closed and if so, there is your problem. Also, at this time, check the water temperature. It should be at least 120 degrees F for the soap to be effective.

Hope this helps, Ken

I have this same problem, plus the pre-wash soap dispenser doesn't open sometimes even though a service guy replaced that. Could he have replaced just one side and not the other? this dishwasher also has a new motor. sometimes it washes beautifully. but other times it does not. even if both dispensers opened.

If you are you using a liquid soap or packets that will be the main problem.If your unit fills with water circulates the water and drains the water,and also heaters are working then you probally need to change to cascade powder soap.The film on the dishes is soap.The unit has so much build up in it that when it gets to the rinse cycle it is rinsing dishes with soapy water.You need to get 2 medium bowls fill both 2/3 up with white vinager,place one in upper rack and one in lower rack and run unit on longest cycle letting the vinager splash out during this with no soap and no dishes.Having soft water will allow you to use less soap.

Soap not dispensed and dishes not washed

water is getting past the gasket during the start up cycle. by the time the door opens, the water has caked up the soap. also, its not clear when in the cycle the door is opening.
try using liquid soap.
also, take a peek just after the machine has finished filling and starts washing to see if the door is opened on the soap disp.
good luck

Dishwasher not cleaning dishes. Casade cleaner not disolved.???

Run the unit with no soap, after about 5 min. of run time open door and check to see if water is clear or soapy,If soapy then you are having an oversudsng issue.When your washer gets to rinse cycle, your unit (if oversuding),will be rinsing with soapy water and the the drying cycle bakes the soap on dishes.You might be having a white film on your clear glasses.Cut down on soap especially if you have soft water.powder soap is best.Your dishwasher will fill , wash , the drain.Its what you put into it that will cause dishes not become clean.
