A method of controlling an Internet washing machine is disclosed, in which the electric power required to keep the Internet washing machine be in a remote-controllable state can be reduced. The method of controlling the Internet washing machine comprises the steps of counting down the remaining time from a point of time when the internet washing machine is turned on, starting a remote control mode by connecting an on-line server with the internet washing machine so that they are in a state of a session if an operating part does not work during the preset time, and starting a power saving mode if either the operating part does not work or a signal for remotely controlling the washing machine is not generated before the preset time from a point of time when the remote control mode is started.
