What controls the water level in a washing machine?
The water level in a washing machine is controlled by a combination of sensors and mechanical components. The primary sensor responsible for controlling the water level is the pressure sensor, also known as the pressure switch. This sensor measures the pressure of the water in the tub and sends a signal to the control board when the desired water level is reached.
The control board then uses this information to control the water inlet valve, which regulates the flow of water into the tub. The water inlet valve is typically an electrically operated valve that opens and closes to allow water to flow into the tub. The control board also monitors the water level and adjusts the water inlet valve accordingly to maintain the desired water level.
How does the pressure sensor work?
The pressure sensor works by measuring the pressure of the water in the tub. As the water level rises, the pressure increases, and the sensor sends a signal to the control board. The sensor is usually a small tube or hose that connects to the bottom of the tub and is filled with air. As the water level rises, the air in the tube is compressed, which increases the pressure.
The increased pressure is then detected by the sensor, which sends a signal to the control board. The control board uses this signal to determine the water level and control the water inlet valve accordingly. The pressure sensor is a critical component of the washing machine’s water level control system, as it provides accurate and reliable measurements of the water level.
What is the role of the control board in controlling the water level?
The control board plays a crucial role in controlling the water level in a washing machine. It receives signals from the pressure sensor and uses this information to control the water inlet valve.
