Understanding Pressure Sensors

A pressure sensor is a vital component in a washing machine that allows it to monitor and regulate the water level during the wash cycle. It measures the pressure or force exerted by the water in the machine and sends a signal to the control board to adjust the water intake or drain accordingly.

The pressure sensor consists of a small air chamber connected to a diaphragm. As the water level rises or falls in the chamber, it exerts pressure on the diaphragm, which in turn changes the electrical resistance of the sensor. This change in resistance is detected by the control board, enabling it to determine the water level inside the machine.
