ABSTRACT:
A system (10) for controlling the flow of temperature selected water to the tub of a washing machine. Individual solenoid operated inlet valves (12,15) are employed to admit and control mixing of water from a heated and unheated source. The temperature selected mixed water is discharged through a third solenoid operated diverter valve (24) yielding a high rate of flow when the solenoid thereof is deenergized and a lower rate of discharge to the tub when the flow control valve solenoid is energized by the water level sensing switch (48) associated with the tub. A timer controlled switch (82) interrupts the power to the hot and cold filling valves to provide stepped filling during agitation during washing and rinsing cycles. The valve assembly employs only three solenoid valve operators.
