What the serial number can tell you

Supported dishwasher serial numbers can reveal a year, a production week, or a month-year window. That is usually the fastest way to estimate appliance age when service paperwork is missing.

What the model number can tell you

The dishwasher model number helps identify the product family, trim, and OEM platform. It becomes more important when the serial code alone does not fully resolve the decade or when the dishwasher is sold under a private label.
