Bendix Door Lever
Kevin,
You're right in saying the lever operates the door latch. On the one we had, it worked in either direction, mechanically lifting the latch to release the door tongue. There was also a small button on top of the chrome, above the latch knob, which I don't see on this model. It was a "childproofing" feature in that the button needed to be pressed down in order to unlock the lever, which could then be moved to open the door. If the control panel lid was closed, and bearing in mind it was steel and therefore comparitively heavy for a child to lift, it did offer some protection against a child opening the door mid-cycle and getting scalded with the hot wash water tumbling out over him.
