Abstract

A hydraulic system for a household appliance which includes a pump that is driven by an electric motor, an outlet conduit in fluid communication with an outlet of the pump, a magnetic check valve having a flap and a control unit. The control unit is configured to control the speed of the electric motor in a closed loop and to determine whether the flap of the check valve is in an open position or in a closed position based on the torque of the electric motor estimated from the current consumption of the electric motor and/or the voltage in the terminals of the electric motor.
