Abstract: PURPOSE: A control method of a washing device is provided to prevent a motor in a driving condition situation of limitation. CONSTITUTION: An input current is measured in a driving initial of washing device(S100). After a current measuring step, a voltage is recompensed as a real input voltage by measuring the voltage(S200). A current of a motor which rotates a drum while driving is measured(S300). In a voltage compensating step, a resistance value of a motor coil is converted as the coil temperature through a recompensed voltage value and a measured current voltage(S400). If the coil temperature is over the preset setting temperature, overheat of a motor is determined(S500). If it is determined as motor overheat in determining step, a motor cooling program is operated(S600).
