Abstract
Abstract A latch is operable for positively locking a front-opening, bottom-hinged dishwasher door in an open substantially horizontal position to prevent an upsetting of the appliance when an overload is applied to the open door. The door is locked relative to the cabinet so that the engagement of the door with the floor, after a small amount of tipping of the dishwasher, will prevent further tipping.
