Supported Bosch-family FD example. This is one of the clearer dishwasher date paths because the FD code points to year and month more directly.
Use this dishwasher serial number lookup page to find the label, decode supported serial formats, and move into the strongest brand path when the age code depends on the manufacturer.
Dishwasher age checks usually start with the serial number on the door frame or tub lip. The model number helps confirm the product family or OEM source when the serial format repeats or when the brand is private-label.
Select the dishwasher brand and enter the serial exactly as printed.
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.
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.
| Pattern | Common Format | What It May Indicate | Confidence |
|---|---|---|---|
| Bosch-family dishwashers | FD code | The FD digits usually map directly to production year and month. | Higher confidence when FD is present. |
| Whirlpool-family dishwashers | 9 or 10 characters with year code + week | The year code position changes with serial length and is followed by week digits. | Estimated decade. |
| GE dishwashers | Opening month/year letters | The first letters usually carry the age logic. | Estimated decade. |
| Frigidaire dishwashers | Factory letters + year/week digits | The first numeric digit after the factory code often indicates year, followed by week digits. | Estimated decade. |
| Samsung / LG dishwashers | Brand-specific month/year positions | Samsung uses serial-length-dependent positions. LG uses an opening year digit plus month digits. | Estimated decade. |

Illustrative Frigidaire dishwasher pattern. The factory letters matter before the year and week positions are read.
Open the door, locate the product tag on the frame or tub edge, and decode the serial number after selecting the correct brand.
It usually identifies the product family and can help confirm the OEM platform or generation when the serial result stays estimated.
Common reasons are a worn tag, the wrong brand path, an OEM/private-label mismatch, or a repeating year code.
Most dishwashers place it on the inner door frame, tub lip, or side edge that is visible when the door is open.
Yes. The result is useful for age support and replacement planning, especially when paired with the model number and product type.
