If you didn't see your dishwasher's problem on the main list of symptoms, you might find what you're looking for here. Below are instructions for fixing the door spring if the door drops open too fast, how to replace the detergent dispenser if it's not releasing the dish detergent, as well as links to troubleshooting videos.
These repairs may help solve your dishwasher problem
Replace the dishwasher door hinge spring
A door hinge spring attaches to each side of the dishwasher door hinges. The door springs provides tension when the dishwasher door opens so it doesn't drop down too quickly. If a spring is broken, the door drops without control, and the door springs need to be replaced. Replace both springs so the sides have equal tension.
The dishwasher won't start if the door isn't completely shut and latched. If the door doesn't latch shut, replace the latch mechanism. Even if the door latches fully, a problem with micro-switch in the door latch/switch assembly could keep the dishwasher from starting; in that case, replace the micro-switch.
One reason a dishwasher won’t start could be a broken dishwasher latch assembly—the assembly includes the latch itself and a microswitch. You can replace the latch assembly yourself in about half an hour, following the steps in this repair guide and video.
Replace the detergent dispenser if it leaks or is physically cracked or broken. Another sign that you may need a detergent dispenser replacement is if it won't open properly during the dishwasher cycle. Additionally, if the latch on the dispenser is broken, consider replacing the entire dispenser assembly.
When the control panel, also called the control console, becomes visibly loose or damaged, replace it. A stuck button can also cause the dishwasher to become unresponsive. A light may flash constantly on the control panel when a button is stuck.
Replace the dishwasher heating element if it's visibly broken or not heating properly. If the heating element isn't visibly broke, check for a wiring failure, control failure or a blown fuse in the heating circuit before replacing the heating element-those issues could also be responsible for the heating element not working properly.
Your dishwasher gives some clear clues if the dishwasher's heating element stops working: the water doesn't get hot (no steamy kitchen) or your dishes don't dry. You can replace the heating element in less than an hour, following the steps in this DIY repair guide and video.
Because the electronic control board runs every stage of the dishwashing cycle, it's hard to know if the problem is the board or something it controls. If you or a repair technician determines the dishwasher control board is faulty, this repair guide and video show how to install a new one.
The dishwasher door hinge is attached to a spring. It pivots on a pin to allow the door to open and close in a controlled manner. If the door hinge is damaged, it won't allow the door to open and close properly. In that situation, replace the door hinge.
