Open your Bosch dishwasher's door. Look on the right side of the door's edge for a white label.
Write down the model number and serial number. The model number is located on the left side of the label. The serial number starts with "FD" and is located directly below the model number.
Dial the Bosch customer service phone number at 1-800-944-2904. Read the model number and serial number of your dishwasher to the customer service associate. She will be able to tell you the production date of your dishwasher. Write the date down for future reference.
Visit the Appliance 411 website (see Resources). Select "Bosch" from the "Brand" drop-down menu and choose "Dishwasher" from the "Appliance Type" menu. Type in your serial number and model number in the appropriate text boxes. Press "Get Date" to see your Bosch dishwasher's production date.
