WM Water Sensor Haier PS2SP-PC-B2

Description

The Haier PS2SP-PC-B2 / 0024000399A Electronic Water Level Pressure Switch is a vital control component designed for automatic washing machines. Operating on a low-voltage DC 5V circuit, this sensor regulates the exact volume of water entering the machine during a wash cycle. As water fills the drum, it pushes air through an attached tube into the sensor. The sensor measures this air pressure and sends a real-time signal to the washing machine’s main control board, letting it know exactly when the target water level has been reached so it can shut off the inlet valves. Common Symptoms it Fixes: Replacing a faulty pressure sensor resolves issues like: Overfilling or underfilling with water. The machine getting stuck on the filling cycle and refusing to start spinning/washing. Constant draining right after filling. Water level-related error codes displayed on the digital panel (e.g., Haier error codes).
