Machine along with Washing Machine Water Amount Command


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

Through the fill part of the washing machine cycle, a routine 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 until the proper water level is reached, not operating time is lost during the fill process.

Earlier types of washers used a float-type switch to manage water level in the washer. As they are now obsolete we’ll keep our discussion to the pressure-type of water level switches. Modern washers now work with a pressure-type switch علت نشت آب از زیر ماشین لباسشویی. A line is connected to an air bell on the bottom of the outer tub. After that it connects to the pressure switch – which will be usually mounted behind the control panel. Since the washer is full of water, an air pocket is formed in the plastic hose. Since 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. Since the water drains from 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 during a fill cycle your washing machine may overflow water on to the floor and cause unwanted damage.

One reason for overflow that I’ve seen on numerous occasions is a force 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 provided for the pressure switch in the top of control panel with a pressure tube, which sometimes gets clogged with undissolved laundry detergent. A simple way in order to avoid this really is to run the laundry cycle in the warm/warm or hot/warm water temperature setting. This will make sure that the detergent properly dissolves and isn’t deposited in the air-dome or pressure tubing.
