ABSTRACT Structure is provided for dispensing an additive into a wash chamber of a dishwashing apparatus at a predeter- mined stage in an operating cycle for the apparatus. A reservoir is provided for a supply of additive. A cover is movable between a closed position, wherein it seals the reservoir and an open position, wherein the reservoir is in communication with the wash chamber. The timer mechanism moves a link through a prescribed path as the dishwashing apparatus cycles and at one stage in the cycle moves the link through a portion of the path in a first direction and at another stage the link retraces the path portion in an opposite direction. As the link moves in the first direction in the path portion it intercepts and moves a trigger arm and an associated member so that the cover moves from its closed position to its open position. Movement of the link in a direction opposite to the first direction causes the trigger arm to move relative to its associated member as the link portion encounters and moves beyond the trigger arm without moving the cover so that the cover will be maintained in its closed position.
