Abstract
A door locking mechanism for an appliance provides a bolt that may be moved by an actuator between an extended and retracted position. A bolt stop mechanism blocks movement of the bolt in retraction at one of two positions, depending on how the bolt was extended before the retraction. In this way the bolt automatically retracts when the door is not present because this causes extra extension of the bolt and an over-travel position need not be directly sensed reducing controller complexity or wiring.
