(57) The water supply system comprises
a control unit (ECU) to be associated with a washing machine (M),
a supply hose (2) intended to be connected between a water source (3) and the machine
(M), to convey a flow of water into the machine (M),
a solenoid shut-off valve (5), normally closed, positioned between the hose (2) and
the water source (3) and provided with an operating winding or solenoid (11), and
a safety hose (14) which extends around the supply hose (2), between the solenoid
valve (5) and the machine (M), and in which insulated electrical conductors (13) extend,
for connecting the winding or solenoid (11) of the valve (5) to the control circuit
means (ECU).
The winding or solenoid (11) of the solenoid shut-off valve (5) is made so as to be
operable by an extra-low voltage, and the control unit (ECU; 17) is predisposed to
cause the application of an extra-low voltage to this winding or solenoid (11).
