ELECTRIC DEVICE AND WASHING MACHINE AND METHOD FOR CONTROLLING THE SAME

PURPOSE: An electrical instrument, a washing machine, and a control method thereof are provided to save time and water by deciding as a microcomputer disorder if a direct current voltage is lower than a reference voltage and as a power off if a direct current voltage is higher than a reference voltage. CONSTITUTION: A control method of a washing machine comprises the following steps. Operating information is stored while being processed an operation according to a drive course which is set by user(201). A reason of a reset is decided based on a direct current link voltage of a constant size if microcomputer is reset(202). An operation of a relay which is connected to a power source is controlled if the reason of the reset is confirmed as a microcomputer disorder(205). A remaining cycle is processes by checking operating information if the microcomputer is reset(208). Whether the operating information is operation completion or not is decides(207). The operation of the relay is stopped if the operation completion(209).
