A household appliance comprising a heating circuit (140) for heating a fluid comprising a heating element (150) that can be selectively energized (155) to determine the heating of the fluid, and a monitoring unit (125) for monitoring the operation of the heating circuit. The monitoring unit (125) is configured to monitor at least one electrical potential internal to the heating circuit (140), wherein said at least one electric potential internal to the heating circuit (140) is at least one among: - an internal electric potential detected at a first terminal (160b) of the heating element (150) connected to an on/off switch (155) of the heating circuit (140); - an internal electric potential detected at a second terminal (160a) of the heating element (150) connected to a main switch (135) of the appliance or to a safety switch provided for switching the heating circuit off in case of malfunction of the on/off switch (155)
wherein the monitoring unit (125) is further configured for: - detecting a value of the voltage of the electricity distribution network; and - calculating, starting from the detected value of the voltage of the electricity distribution network, a first and a second reference electric potentials, - comparing said at least one detected internal electric potential with the first and second reference electric potentials; - recognizing a state of good operation or malfunction of the heating circuit (140) in case said at least one detected internal electric potential does not fall within a range of values comprised between the first and second reference electric potentials.

The present invention relates to a method for washing laundry (10) in a laundry washing machine (1), the laundry washing machine (1) comprising a washing tub (3) external to a washing drum (4) suited to receive said laundry (10), a water supply system (15) suitable to convey water (W) to the washing tub (3), a water flow sensor (16) associated to the water supply system (5) for measuring an amount of water introduced into the washing tub (3), a liquid level sensor device (19) suitable for detecting an overflow level (Lo) of liquid in the washing tub (3) and to communicate the reaching of the overflow level (Lo) to a control unit (22) which causes stopping of said machine (1) accordingly. The method comprises one or more steps of conveying water (W) from the water supply system (15) to the washing tub (3) wherein the quantity of water introduced inside the washing tub (3) is controlled according to the values of the liquid level (Ld) detected by the water flow sensor (16). The method comprises detecting the liquid level (Ld) inside the washing tub (3) by means of the liquid level sensor device (19) and if the liquid level (Ld) reaches a safety level (Ls) which is below the overflow level (Lo) then the quantity of water introduced inside the washing tub (3) is controlled according to the values of the liquid level (Ld) detected by the liquid level sensor device (19) instead of according to the values detected by said water flow sensor (16).
