A washer’s pressure switch setup detects the washer’s water level.As the washer fills with water, the air that was in it is displaced, and has no way to escape but through the hose, gradually increasing the pressure on the switch.
How do sensors work in automatic washing machine?
In a washing machine, the Hall Effect sensor is mounted onto a printed circuit board in the electronics panel or onto the frame of the appliance, and a magnet is mounted on the rotating dial. When the dial is turned, the magnet rotates and changes the magnetic field detected by the Hall Effect sensor.
Is pressure sensor used in washing machine?

What type of sensor would be used in a washing machine?
Modern machines use thermistors as Temperature Sensors. Thermistors are low-cost temperature-sensitive resistors and are constructed of solid semiconductor materials which exhibit a positive or negative temperature coefficient.
What is a washer sensor?
This is a replacement sensor assembly for your washer. It may also be known as a motor rotor position sensor. The sensor assembly monitors the direction and speed of the spinning rotor and communicates this information to the electronic control board.
How do you test a pressure switch?
Test the Switch for Resistance
Disconnect the wires connected to the pressure switch by pulling the wire connectors off of the switch terminals. Set a multimeter to test for resistance (ohms). Touch each tester probe to one of the switch terminals. The tester should read 0 or close to 0 (indicating no resistance).
What does pressure switch do?
Pressure switches are important components for controlling the activation and deactivation of pumps in fluid systems when pressure thresholds are reached. They are also used in process control systems for maintaining steady pneumatic or mechanical pressure.
Why is my washing machine not draining?
Your washer may have a clogged drain hose or the pump may be broken. A broken lid switch or belt could also be the culprit. It may even be something as simple as the hose being jammed.

On a machine without a reset button, unplugging the washer and then plugging it back in often serves as the means to reset it.
What is IR sensor?
An infrared sensor (IR sensor) is a radiation-sensitive optoelectronic component with a spectral sensitivity in the infrared wavelength range 780 nm 50 µm. IR sensors are now widely used in motion detectors, which are used in building services to switch on lamps or in alarm systems to detect unwelcome guests.
Where is the water level sensor on a washing machine?
The water level switch (aka pressure switch) senses the water level in the wash tub. It does this through a plastic tube which runs from the switch in the control console down to the side of the outer tub, near the bottom . The tube is filled with air. As water enters the tub it also enters the tube.

What happens when a pressure switch goes bad?
It’s what senses when water pressure has dropped to the point where the pressure tank requires more water. The switch then powers up the well pump. If the switch is bad, it won’t start the well pump and you won’t have water, so testing the switch is your first step.
How can you tell if a pressure switch is bad?
Here are some tell-tale signs that your pressure switch is beginning to fail:
- Your water pressure is at or above the cut-out pressure, yet the pump doesn’t turn off.
- Your pump doesn’t turn on at the proper cut-in pressure.
- You have low water pressure even though the pump is running.
