FIELD: electricity.
SUBSTANCE: household electric appliance, washing or drying one, containing heating loop (140) for heating of washing liquid or air flow for drying, while the heating loop is connected to the power supply lines (105a, 105b) providing power supply for the electric device and contains, at least, one thermoresistor (205) which is series connected to the switching devices (210a, 210b) operated by means of the control device (125) for selective activation of the thermoresistor when required. The switching devices of the heating loop contain the first and the second switches (210a, 210b) which are series connected to the thermoresistor, and the thermoresistor is installed between the first and the second switches. The electric device also has the control loop containing the first resistor (R1) connected parallel to the thermoresistor, the resistance of which is much higher, than that of the thermoresistor, and the load circuit connected between the first contact (215b; 215a) thermoresistor and one of power supply lines; while the actuation device is powered by the voltage corresponding to electric potential on the second contact (215a; 215b) of the thermoresistor.
EFFECT: invention provides comprehensive monitoring of the device operation.
