Using your Westinghouse WSF6602 dishwasher control module is simple. First, make sure your dishwasher is unplugged or turned off at the breaker. Then, carefully remove the old control module and install this new one in its place. It's designed to fit easily, but be gentle when connecting the wires. When it comes to maintenance, keep the module clean and dry. Wipe it down occasionally with a soft, dry cloth. If you notice any issues like error codes or strange behavior from your dishwasher, check the connections first. If the problem persists, don't hesitate to contact us. And remember, if you're ever not sure if this module is the right fit for your dishwasher, give us your model and PNC numbers, and we'll help you out.
