A hinge assembly for an appliance comprises a channel and a stop connected to the channel. A door mounting lever pivots relative to the channel about a pivot axis on an arc between a first operative position where the door mounting lever is moved a maximum extent in a first direction about said pivot axis on the arc and second operative position where the door mounting lever is moved a maximum extent in a second direction opposite the first direction about the pivot axis on the arc. A glide is operatively coupled to the door mounting lever, e.g., by way of a spring cam member, and is movable slidably on the stop in response to movement of the door mounting lever. A spring biases the glide into continuous engagement with the stop when the door mounting lever is located in both the first and second operative positions and when the door mounting lever moves between the first and second operative positions.
