The age of a dishwasher is dependent on the date of manufacture. A homeowner can find out the age of a dishwasher by looking at the manufacturer sticker printed on the appliance. Subtract the year of manufacture from the current year to learn how old the appliance is.
If the sticker is not available on the dishwasher, a homeowner can contact the manufacturer to find out the age of the appliance. Provide the manufacturer with the model number of the appliance to get its age. Some online experts also help people find out the ages of their appliances by using the model numbers.
