Check a documented system

What’s on the rating plate?

Speed Queen laundry products whose serial structure matches Alliance source manuals.

Spaces and dashes are accepted. Check O/0 and I/1, and keep any leading zeros.

Checks ENERGY STAR model records and searches manuals separately from the serial. Certification records do not establish this unit’s manufacture date.

Known product context (optional)

Choose a system only when it matches the product family and its documentation. A purchase year or a manual’s publication date does not establish a manufacturing date.

Scope matters

Supported formats
and historical limits.

  • A serial date code does not normally encode the full model number. Read the separate model/E-Nr/product code on the rating plate.
  • Older Raytheon-era formats require separate documentation.
  • Industrial letter suffixes are not the Maytag year/month suffix cipher found on unrelated brand tables.

Research reviewed October 16, 2026. This independent tool applies published rules and retains unresolved years and model candidates.

Source references

Alliance numeric YYMM prefix

Alliance/Speed Queen laundry products using the ten-digit numeric system, confirmed in Alliance installation manuals.

The date is month-level; the two-digit year omits the century. Do not replace this with a week interpretation. Older Raytheon-era and imported industrial suffix systems need separate rules.

Alliance industrial year/month suffix

Commercial hardmount washer-extractors listed in D1599EN, including relevant Speed Queen-badged industrial units.

Year values are the documented chart plus the explicit DK example. This is not an extrapolated alphabet or a universal Speed Queen suffix rule. The complete manufacturer chart now adds verified year letters for2009–2014 and2016–2019; all prior mappings and family restrictions remain unchanged.

Confirm the family: commercial hardmount washer-extractor D1599EN models

Reading your result

Speed Queen lookup questions

Why does the year code match more than one year?

Some systems reuse letters or only encode the last one or two year digits. Every supported interpretation is retained. A decade supplied from reliable records can narrow the reading; the tool does not automatically pick the newest year.

Does the serial identify my exact model?

Usually the model is a separate plate field. Where published serial ranges actually identify a model, the result shows model candidates and links to their manuals. Overlapping ranges remain ambiguous.

Can I share the result?

After a lookup, the address includes the serial in a fragment beginning with #serial=. Use “Copy share link” to share the serial and selected context. Opening the link runs the same lookup. The fragment is not a query-string result page.
