My soap dispenser cover won't snap shut . I removed the panel inside the door and determined there is nothing wrong with the simple parts that move the soap dish. The culprit is the white plastic actuator arm protruding from the timer. I found a piece of broken black plastic protruding from under the timer cover, and pulled it out. its obviously related to the inoperability of the white actuator arm. I can't see how to remove the black plastic cover over the timer mechanism to further investigate. I see no screws, and I fear if I pull hard, it will break something. The cover is very flimsy, but doesn't seem to want to snap off whatever is holding it on. Anyone know how to get it off without breaking it?
