How Does A Washing Machine Water Level Sensor Work?
A washing machine water level sensor works by monitoring the amount of water in the washing machine drum. It typically uses a pressure sensor to measure the air pressure in a small air chamber created by a tube or hose in the washing machine. As the water level in the drum rises, so does the air pressure in the chamber. The sensor then sends a signal to the control board to adjust the water level or initiate the next cycle once the desired water level is reached. Some models may also use a float switch to detect the water level instead of a pressure sensor.
