The main PCB (Printed Circuit Board) in a dishwasher is responsible for controlling and coordinating the various functions and operations of the dishwasher. The PCB acts as the "brain" of the dishwasher, receiving input from user controls, sensors, and other components, and then sending signals to different parts of the dishwasher to perform specific tasks such as water intake, heating, motor control, and drainage.
The PCB is typically located inside the control panel or the door of the dishwasher. It contains electronic components, including microprocessors, relays, capacitors, and other circuitry necessary for the dishwasher's operation. The specific design and components of the PCB may vary depending on the make and model of the dishwasher.
It's worth noting that while the main PCB is crucial for the dishwasher's functioning, there are other control modules and components involved in the dishwasher's operation, such as the user interface panel, motor control module, water inlet valve, heating element, and drain pump, among others.
