Using the Westinghouse WSF6606 dishwasher control module is easy. First, make sure your dishwasher is unplugged or turned off at the circuit breaker to avoid any electrical hazards. Then, carefully remove the old control module following your dishwasher's user manual. Take note of how the wires are connected so you can attach them correctly to the new module. Once the new module is in place, plug your dishwasher back in and test it. As for maintenance, keep the area around the control module clean and free of debris.
