- 3Review the date estimate, notes, and fallback links if the serial does not decode.
Washer serial numbers usually carry the stronger age signal. The model number helps confirm the generation and OEM family when the serial result stays decade-ambiguous.
Select the washer brand and enter the serial exactly as shown.

What the serial number can tell you
On supported brands, the washer serial number can point to a manufacturing year, production week, or month-year window. That is usually the fastest way to document appliance age when purchase history is missing.
What the model number can tell you
The washer model number helps identify the family, platform, and OEM source. It is especially useful for Kenmore, Maytag-era overlap, and older products where the serial code alone is not enough to lock the decade.
Common washer serial number formats
| Pattern | Common Format | What It May Indicate | Confidence |
|---|---|---|---|
| Whirlpool / Maytag post-2006 | 9 or 10 characters with year code + week | Many modern Whirlpool-family washers store the year code early in the serial and follow it with week digits. | Estimated decade. Use era or model clues if needed. |
| GE washers | Opening letters for month and year | The first two serial letters are usually the useful timing positions. | Estimated decade. GE cycles repeat. |
| LG washers | Year digit + 2-digit month | The opening three characters usually hold the age signal. | Estimated decade. |
| Samsung washers | 11-char or 15-char serial | Year and month positions change by serial length. | Estimated when year codes repeat. |
| Kenmore washers | OEM-dependent by model prefix | The model prefix often decides whether the washer follows Whirlpool, GE, LG, or Frigidaire logic. | Estimated until OEM is confirmed. |

Where to find the serial number
Top-load washers
- Under the lid or around the opening rim
- Rear console or back panel on some brands
Front-load washers
- Door opening or frame edge
- Back panel or lower service area if the front tag is missing
Documentation fallback
- Owner manual or purchase paperwork
- Registration records when the label is worn
Common problems
- Top-load and front-load labels are in different places on the same brand family.
- The serial result is decade-ambiguous because the manufacturer repeats year codes.
- Only the model number is available after a control-panel or cabinet replacement.
- A Kenmore washer needs the model prefix first before the serial can route to the right OEM.
- A laundry center or stacked unit hides the tag near the opening or rear panel.
FAQ
How do I tell how old my washer is?
Find the serial label, choose the correct brand, and run the serial number through the decoder.
What can the washer model number tell me?
It usually identifies the product family, the likely generation, and in some cases the OEM platform that built the washer.
Why does the washer serial number not decode?
Common reasons are a hidden label, a partial serial, the wrong brand path, or a repeated year code that still needs model-era context.
Where is the washer serial number label located?
Top-load models often place it under the lid, while front-load models usually place it around the door opening or on the rear panel.
Can this help with claim documentation?
Yes. Serial results are useful for age support, but the file should note when a decade is still estimated.
