As the washer fills, water enters the tube from the bottom and increases pressure in the airspace within the tube. When the pressure reaches the critical point, the switch shuts off water flow to the tub.
How does a pressure control switch work?
Pressure switches rely on water pressure to do all the work. The change in pressure that activates the switch is provided via the water from the well. The pressure moves up through the diaphragm which presses against a piston and spring, which in turn opens or closes the contacts.
How does washing machine sensor water level?
The level sensor uses a pressure switch to detect the water level in the tub. This switch controls how high the tub fills with water. The big end of the hose connects to the bottom of the tub, while the small end connects to the switch.
