These devices control the flow of water into the appliance, ensuring a regulated supply for each wash cycle. A typical washing machine utilizes two of these, one for hot water and one for cold, allowing the appliance to mix water to the desired temperature. Malfunctioning units can lead to leaks, inadequate water supply, or even flooding.
Proper function of these components is critical for efficient and safe operation of laundry appliances. They prevent water waste by precisely metering the necessary volume for each cycle and safeguard against potential water damage caused by leaks. Historically, simpler mechanisms were employed, but modern designs incorporate features like solenoid valves for more precise electronic control, contributing to both water conservation and appliance longevity.
