ABSTRACT:
A washing machine and an operating method thereof are provided. The washing machine detects an input voltage, and increases or reduces a wash time according to the input voltage. Thus, the washing machine can precisely calculate a wash time by reflecting a heating time that varies according to the input voltage. In addition, the washing machine can improve user convenience by enabling a user to easily determine the progress of a washing operation and the end time of the washing operation.
