Regardless of the brand or design of water level switch utilized on Whirlpool, Maytag, Kenmore, GE, Frigidaire washers, it’s main function is to control the amount of water that enters the tub. When the proper water level is reached in the washer, the switch completes a signal to the timer motor, machine motor and agitator control.
Throughout the fill portion of the washing machine cycle, a signal 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.. considering that the timer motor doesn’t operate before the proper water level is reached, not operating time is lost throughout the fill process.
Earlier models of washers used a float-type switch to control water level in the washer. Because they’re now obsolete we’ll keep our discussion to the pressure-type of water level switches. Modern washers now work with a pressure-type switch. A hose is linked 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. Because the washer is full of water, an air pocket is formed in the plastic hose. Because 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 علت ماندن آب در جاپودری ماشین لباسشویی. Because 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. When these washer pressure hoses split or rupture within a fill cycle your washing machine may overflow water on to a floor and cause unwanted damage.
One reason for overflow that I’ve seen on numerous occasions is a stress hose clog. Remember, the pressure switch receives air pressure that is generated from the basket water that exerts it’s pressure to the air bell in the outer basket housing. This air pressure is delivered to the pressure switch in the top of control panel via a pressure tube, which sometimes gets clogged with undissolved laundry detergent. A straightforward way to prevent that is to operate the laundry cycle in the warm/warm or hot/warm water temperature setting. This may ensure that the detergent properly dissolves and is not deposited in the air-dome or pressure tubing.
