It is normal for a dishwasher door without a kitchen door fitted not to remain open. It will be closed again by the springs on the hinges. If the dishwasher is integrated and no kitchen door is attached, it will not be possible to test the door.

May be this is the reasons.

a) May be your door latch is opening due to pressure inside the dishwasher. The door latch opens and the dishwasher will stop. Quite common problem on KITCHENAID. KitchenAid door is a heavier door compared to sister product WHIRLPOOL. If door latch problem then has to change the door lock along with the top latch.

Pull the door latch towards the front of the dishwasher until it clicks in the open position.

your door is not staying latched.. imagine if it did stay running and the door came completely open, what a mess that would be. so there are safety switches that help stop the washing if the door opens. not too sure how to fix your exact washer.. but the problem is the door not staying closed. maybe you can jamm the door shut while it is running? its not the best answer, but probably the most free way to fix it

Hi
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...

Chaney,
Make sure there is nothing in the way of the soap door when you close the dishwasher.
Close the dishwasher door slowly and look down in side with a flashlight, are any of the rack brackets or silverware basket directly in front of the dispenser door.
Take a look and let me know.
Regards.

On each side of the dishwasher, near the ground, is a nylon cord and pulley apparatus that keeps the door from flopping down when opened. It probably needs some adjustment of the tension on the cord.

sounds like a faulty door switch not sensing that the door is shut. test the switches for continuity to determine the faulty switch

it is a very tiny plastic "tooth" that let open automatically the door when the washing program selected reach the opening point, the only good solution I suggest is to add the detergent after the first hot wash (just open the main door and drop it in!)...of course the best is to change this door locker with a new one...good luck!
