Using this control panel is simple. Just align it with the designated area on your Westinghouse WDF901WA dishwasher and secure it in place. When handling, be gentle as the panel can be brittle. Since it's no longer available from the manufacturer, take extra care. For maintenance, clean it regularly with a soft, damp cloth. Avoid using abrasive cleaners as they can damage the surface. If you notice any signs of cracking or damage, replace it promptly to ensure the proper functioning of your dishwasher.
