The washing machines Printed Circuit Board (PCB) is a board with electrical parts, that often functions like the brain of the machine. Nearly every function performed by your washing machine is controlled by the PCB Assembly. If the circuit board goes offline or shorts out, then the washing machine will stop working, because it does not know how to perform its functions. This means the circuit board is a critical part that should be replaced as soon as possible. Please check model fit list to ensure this part is correct for your model.
