Washer Repair Meridian Idaho | Washing Machine Water Level Control

Washer | Washing Machine | Water Level Control

Regardless of the brand or design of water level switch used on Whirlpool, Maytag, Kenmore, GE, Frigidaire washers, it’s main function is to control the amount of water that enters the tub. As soon as the correct water level is reached in the washer, the switch completes a circuit to the timer motor, machine motor and agitator control.

During the fill portion of the washing machine cycle, a circuit is completed through the pressure switch contacts to either one or both of the water control valves on the water inlet, permitting water to enter the washing machine.. since the timer motor does not operate until the proper water level is reached, not operating time is lost during the fill process.

Earlier models of washers used a float-type switch to control water level in the washer. Because they are now obsolete we’ll keep our discussion to the pressure-type of water level switches.

Modern washers now use a pressure-type switch. A hose is connected to an air bell on the bottom of the outer tub. It then connects to the pressure switch – which is usually mounted behind the control panel. As the washer is filled with water, an air pocket is formed in the plastic hose. As the water rises in the tub, the air pressure in the tube increases until it is sufficient to cause the diaphragm in the pressure switch to actuate the switch contacts; thus, opening the circuit to the water control solenoid, or valve, and stopping the flow of water into the washer. As the water drains out of the tub the air pressure in the hose gradually decreases allowing the pressure switch diaphragm to reset the switch contacts.
