Reporting a wrong result
Use the correction form rather than email. It captures the rule that produced the result, which is what we need to investigate, and it lets you send everything except the serial number if you would rather not share it.
Everything else
Questions about the methodology, documentation for a serial format we do not cover, or anything about how the site handles data.
What we cannot help with
We are not an appliance manufacturer, a repair company or a parts supplier, and we have no access to manufacturer warranty or service records.
- Warranty claims and registration. Contact the manufacturer directly — their support site is linked from every brand page here.
- Diagnosing a fault. We can tell you how old an appliance is. We cannot tell you what is wrong with it, and diagnosing a safety-critical fault remotely would be irresponsible.
- Finding parts. Take the model number to the manufacturer or an established parts supplier.
- Confirming that an appliance is genuine. A serial number matching a documented format does not establish authenticity.
If you have documentation
The single most useful thing anyone can send us is manufacturer service documentation for a serial format we do not currently cover — Samsung, LG, Speed Queen, Miele and pre-2006 Amana are the gaps we would most like to close. Scanned service manuals and official technical bulletins are exactly what we need to publish a rule.
