Soap running down side of door

The only experience that I have with this type problem was from having dishes blocking the soap door. You can tell if this is the problem when you open the door. The soap door will then open and the soap will run down the door.

May have a stripped wash impeller. I would tear into the pump and look for any kind of obstruction but if its clean probably the motor assembly needs replacing.

Check the way you're loading your dishwasher. Sometimes large plates or baking pans can block the door of the dispenser. The latch unlocks but because the door is blocked, the detergent can't get out. Once you open the main door, the dispenser door may pop open and looks as if it has been in the fully opened position when it was actually held in place by that large utensil!Cutting boards are major blockers as well.
I hope this helps. If it does, please come back to fixya and rate my answer

switch to pre-measured tablets,and throw the tablet directly into the tank(d/w..)it works better that way anyways...most dispensers are very expensive also

you will have to replace the cup / they do go bad . . dw will not clean well if you don't replace it as the dergt need to go in at the right time mm

I noticed you didn't rate out chat and saw that your problem was posted. I'm happy to continue to help you if you encountered problems or were not happy with the solution in your chat session.

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 wash.do this with no soap and no dishes.Having soft water will allow you to use less soap.

its either the dispenser or the timer/pcb.

IT SEEMS YOU SOAP DOOR HAS A BAD SOLENOID ACUATOR OR RELAY

Before taking anything to bits, check you aren't just loading the machine in such a way that something (for us, it's usually a frying pan) is stopping the soap dispenser from springing open all the way. A.
