Detergent door does not open on any cycle. Everything works fine.. Kenmore model 665 1378

SOURCE: Bosch Aquasensor Detergent Dispenser door wont open during cycle

Behind the dispensor door there is a small selanoid you will need to replace this, test to see if its open circuit, alternatively you can just place the detergent in side the machine before you put it on a wash cycle is this would have the same effect. the only cycle you can not do this on is the one with the prewash, I think its number 1.

Use gel run a few cycles and help clear and then don't overfill w gel soap

SOURCE: detergent stays in the dispenser

Clean and dry your dispenser prior to filling with detergent.
Use only fresh detergent.
Do not place anything ie. cookie sheets, cutting boards in the path of the water obstructing the dispenser.
Do not allow anything to fall between the racks and stop the spray arms from turning.
Always turn the hot water on at the sink prior to starting you dishwasher they use less than 2 gallonsof water in the initial cycle and they require 120 deg f water. Unless you have hot water recirculation in your home.
If you have low water volume or low water pressure due to bad impellor or windings in circulation pump. The water volume or pressure will be insuficient to reach the dispenser.

Hi,


1. The most common problem with the detergent doors on KitchenAid dishwashers is that they either don't open during the cycle or open only halfway. Before looking into more complicated repairs, make sure that the door is able to open. Check the seal around the door and the door latch for soap- and food-related gunk, and scrub it off if present. Sometimes this can keep the detergent door from operating properly. Consider switching detergents, as some liquids and pouch-style dish detergents can gum up the detergent dispensers. Also, make sure that there is nothing blocking the detergent door when the dishwasher is loaded. Because of the location of the detergent door, a large item such as a cookie sheet or a pan can prevent the door from opening. Run the dishwasher through a cycle without anything placed in front of the detergent dispenser and see if that solves the problem.
Broken Timer
2. KitchenAid dishwashers rely on an internal timer to complete the wash cycle properly. When this timer malfunctions, certain steps in the wash process (such as the release of soap from the detergent dispenser) can be interrupted. If the dishwasher detergent door is either not opening or appears to be opening late in the cycle, this is likely the mechanical culprit. A broken timer isn't something that's simple to replace without knowledge of dishwasher repair, so it's best to consult a professional if you suspect that this is the problem.
Malfunctioning Door Components
3. For the detergent door to function properly, all of its mechanical components must be in working order. Older dishwashers' detergent doors rely on a spring-loaded hinge to pop all the way open when the timer gives the signal. If the door doesn't swing all the way open instantly when it's manually released, the spring may need to be replaced for the dispenser to operate properly. If the particular model is newer and does not rely on a spring to open the door, chances are it either uses a wax motor or a bi-metal switch to release the detergent door at the appropriate time. If either of these components is dying, that can mean that the detergent dispenser will not operate properly.

Pretty in depth, but not a simple fix.
