A method for controlling filling with water of a water-conducting electrical household appliance (1; 1') having a control system (17), such as a dishwashing machine or a laundry washing machine. After the start of a treatment program of the electrical household appliance (1, 1') the following steps are provided: a) the control system (17) activates the motor of a washing pump (4) and drives it to a first speed; b) after elapsing of a first time interval the control system (17) controls the opening of a loading valve (12) set on a line (11, 14) for conveying water to a treatment container (3) of the electrical household appliance (17), monitors a signal characteristic of the operation of the motor of the pump (4) and starts a time counter; c) when the signal characteristic of the operation of the motor of the pump (4) reaches a first predefined value, the control system (17) controls the closing of the loading valve (12) and stops the time counter; d) the control system (17) calculates a flow-rate value in function of the value assumed by the time counter and calculates, in function of the calculated flow-rate value, a second time interval of opening of the loading valve (12), required to obtain a predetermined volume or level of filling with water of the treatment container (3); e) the control system (17) controls a new opening of the loading valve (12), and f) upon elapsing of the second time interval, the control system (17) controls closing of the loading valve (12). |
