A control method for preventing steam reverse flow in a washing machine is provided to minimize steam outflow into outside by periodically supplementing water to a steam reverse-flow preventing device for preparing that water is flowed out of the steam reverse-flow preventing device. A control method for preventing steam reverse flow in a washing machine comprises the steps for detecting water temperature in a tub; comparing detected water temperature with a set value(S1); and supplying water to a steam reverse-flow preventing device installed on a water supply path when the detected water temperature is over a set value(S2). The step for supplying water to the steam reverse-flow preventing device is repeated at predetermined time intervals so as to open a water supply valve installed on the water supply path for a set time. |
