3. Mechanism
The core mechanism of a GE washing machine pressure switch relies on air pressure sensing. This process translates changes in water level within the washing machine tub into measurable pressure variations, enabling precise control over the fill cycle. As the tub fills, the air inside the connected air dome is compressed, increasing the air pressure within the system. This pressurized air acts upon a diaphragm within the pressure switch. The diaphragm’s movement, in direct response to the changing air pressure, triggers an electrical contact within the switch. This contact, in turn, signals the control board, providing real-time information about the water level inside the tub. This air pressure sensing mechanism effectively converts a physical phenomenon (water level) into an electrical signal, facilitating automated control. Consider a scenario where the desired water level for a specific wash cycle is reached. The corresponding air pressure within the system activates the pressure switch, signaling the control board to shut off the water inlet valve. This precise control ensures the correct amount of water is used, optimizing washing performance and preventing overflows.
The reliability and accuracy of this air pressure-based system are critical. A malfunctioning diaphragm, for instance, can disrupt the accurate sensing of pressure changes. This could lead to underfilling, resulting in inadequate cleaning, or overfilling, causing potential water damage. Similarly, a leak in the air dome or connecting tube can compromise the system’s integrity, leading to inaccurate readings and subsequent malfunctions. Regular inspection of these components is crucial for maintaining proper function. For example, checking for cracks or blockages in the tubing can prevent potential problems.
