This component controls the flow of both hot and cold water into the washing machine. It’s an electrically-operated valve that opens and closes based on signals from the machine’s control panel. Typically, it consists of solenoids that activate diaphragms or plungers, allowing water to pass through when energized and blocking the flow when not. Malfunctions can manifest as inadequate filling, overfilling, or no water entering the appliance at all.
Proper function of this device is essential for regulating water levels during wash cycles. This regulation ensures efficient cleaning and prevents potential overflows or damage caused by excessive water pressure. Over time, advancements in design have led to more durable and precise components, contributing to the overall reliability and efficiency of modern washing machines. These improvements often include features like flow sensors and pressure switches that work in conjunction with the valve for greater control and leak prevention.
