<p>An improved method and an apparatus for driving a pump motor for a refrigerator dispenser which are capable of feeding-back a water remaining in a discharge hose to a water container of the refrigerator by reversely rotating a pump motor after discharging the water from the water container, for thus preventing the water and the discharge hose from being polluted. The method includes the step of a first step for discharging a water from a water container through a discharge hose by driving a pump motor when a lever switch is turned on, a second step for stopping the operation of the pump motor when the lever switch is turned off and finishing the water discharge, and a third step for feeding back the water remaining in the discharge hose to a water container of the refrigerator after a predetermined time after the second step by reversely rotating the pump motor with respect to the rotation direction of the pump motor in the first step.</p> |
