Doug for Model Number Maytag MDB5600AWQ I have a Maytag that does not always get dishes clean and all the detergent will not be washed out of the dispenser. The dispenser door will be open and some detergent will still be in dispenser and sometimes undissolved detergent powder will be running down inside of dishwasher door and out on bottom of dishwasher. A repairman checked heater water inlet, heater element and cleaned wash spray components and he said we needed a new control board. I decided to buy and install board myself. After new board install, dishwasher worked just fine for several days and then started doing same thing as before. I decided it must be the washer pump even though it sounds as though it is spraying just fine. I bought and installed all new washer pump components (no obvious problem with old components) and dishwasher worked fine first time after installing new washer pump components and then started doing same thing again. What triggers the dispenser door to open, I assume it is the control board, is it a timing thing or is a sensor involved, is it possible that the dispenser door is opening to late? Is there something besides the control board that could be causing door to open late? Do you have any suggestions? Is there any way to determine if the dispenser is at fault besides ordering a new dispenser?
Answer Hi Doug . The soap dispenser is opened by a wax valve part # is WP99003317. This is the complete dispenser assy. However it sounds like either you are having it loaded and poss. something is stopping the door from coming open. Or the middle wash spray arm splits open under pressure and does not direct the water to flush out the dispenser soap dish area. This part # is 99002624. Is the middle funnel tube going all the way in the water manifold correctly? Is the water manifold missing the Dishwasher station for the middle funnel to go into if the rack is lifted or not. This part WP6-917647 is connected to the water manifold to open a area for the funnel and keep the other one shut when not in use. This will disrupt proper water flow to the wash arm also. Thank you.
