All models of Frigidaire dishwashers, whether built-in models designed for cabinetry or portable models designed to roll around a room, vary by style, size and features. No matter what the design may be, each dishwasher receives a product label containing its model and serial numbers before it's shipped to dealers. These numbers act as a reference when you register your dishwasher for warranty purposes. They also are required when you call customer service or a dealer for technical assistance, to order accessories and parts or request repair support.
Open your Frigidaire dishwasher's door and check the frame -- left top corner and the left and right sides --for the product label containing the model number.
Check the inside of the door if you don't find the number on the frame.
Close the door and check under the control panel.
Pull the dishwasher away from the wall or turn it, if it's portable, so that you can look on the back and sides of the hose storage area.
