Abstract (en)
[origin: WO2019052664A1] The invention relates to a method for operating a laundry treatment machine (1) comprising a container (4) for housing a laundry load to be treated and a pump (P, 21, 26, 31, 180). The pump (P, 21, 26, 31, 180) comprises an electric motor (140) adapted to be powered by a motor voltage (VMOT) and a motor current (IMOT). An air-water working condition of the pump (P, 21, 26, 31, 180) is detected/evaluated based on values of the motor voltage (VMOT) and/or the motor current (IMOT) of the electric motor (140).
