15. the lever down the first time to release the detergent cup cover the pin moves up but does not raise the rinse injector pump arm When the timer removes power from the actuator the spring forces the rinse injector pump arm end of the pivot arm down The compound slot in the rinse injector pump arm directs the pivot arm pin down the front of the rinse injector pump arm and under a shorter slot in the center of the arm When the timer reaches the middle of the final rinse cycle it again applies 120 VAC to the dispenser actuator which forces the pivot arm up at the rinse injector end As the pin engages the shorter slot it raises the rinse injector pump arm which operates the pump When the power is removed the pivot arm spring forces the pin to the bottom of the slot A leaf spring pushes the rinse injector pump arm to the left so that the pin returns to the original starting position DOOR LATCH ASSEMBLY The door latch assembly has two functions one is to lock the door in a closed position and the other is to operate the door switches Y The door latch assembly consists of the door handle door handle bracket door catch door switch bracket and door switches The assembly is secured to the inner door panel with two locator pins and two screws The handle is hidden by and accessed through the control panel When the door is closed the door strike mounted on the tub forces the spring loaded catch to rotate back until the bott
