Hydraulic control device for liquid- conducting household appliances and systems

A hydraulic control device for liquid-conducting household appliances or systems comprises: - a hydraulic unit (11), having a hydraulic body (15) defining a duct (30) for the liquid, the duct (30) having an inlet (18i) and an outlet (31), the duct (30) being at least partially defined with an electrically insulating material, - an electrical valve arrangement (EV, SH) on the hydraulic body (15), which is electrically switchable between a closing position and an opening position, to prevent or enable, respectively, passage of the liquid between the inlet (180 and the outlet (31) of the duct (30), - a flow sensor on the hydraulic body (15). The flow sensor is a non-mechanical flow sensor comprising at least two electrical detection elements (42), prearranged for contact with the liquid that flows in the duct (30) and carried by at least one support (41), that preferably at least partly extends within, or faces the inside of, the duct (30) and/or has two opposite major faces that are substantially parallel to a direction of a flow of the liquid.
