The detergent cup would not open during wash cycle

I removed the 4 lower Phillips head screws on the lower inside of the door.(thanks to a tip from Robert) This removed the front panel allowing access to the detergent cup. I removed the 6 screws holding the detergent cup. Removed the old detergent cup and gasket. Installed the new cup and gasket and reinstalled the front panel. Amazingly easy. Now it's on to my stove.
