How old is my Sharp dishwasher?

Serial number age decoder for Sharp dishwashers: 1 format era, the decode rule in plain English, transcribed tables, and the official lookup.

Sharp's official lookup at getsupport.sharpusa.com returns warranty / registration lookup.

Format eras

How to read the serial

2010 to 2011 formatPARTIAL

Year: letter 2: T = 2010, V = 2011 (only two letters charted; GE cycle would give S=2009, Z=2012, A=2013)
Week or month: month = letter 1: A=Jan D=Feb F=Mar G=Apr H=May L=Jun M=Jul R=Aug S=Sep T=Oct V=Nov Z=Dec

Documented but not evaluated by the decoder: no example serial.

Trap: No real example: building-center's own sample is masked (ZT######), so example is null and the 6-digit tail is inferred from the mask. Chart covers 2010-2011 only; extending it via the GE 12-year cycle is an inference.

Where the data plate is on a dishwasher

Open the door: the label is on the inner door edge or the side of the tub frame.

General guidance, not brand-specific: the owner's manual or the installer can point to the exact spot. See the data plate guide.

For scale only: the InterNACHI Standard Estimated Life Expectancy Chart for Homes lists Dishwasher at 9 years of expected service (nachi.org). That chart is a guideline, not a prediction for your unit.

Official lookup: the authority

Open the official Sharp lookup takes serial number; returns warranty / registration lookup; URL verified live

This site is a reference built from published tables. The manufacturer's own lookup wins whenever the two disagree.

What we could not confirm

The 2010 to 2011 format is only partially confirmed (PARTIAL (masked example, 2-year chart)).
The 2010 to 2011 format is documented but not decodable here: no example serial.
building-center (2011 chart credited to hisearch.web.officelive.com): ZT###### - letter 1 = month, letter 2 = year, with only T=2010 and V=2011 charted. The month letters (A D F G H L M R S T V Z) and T/V year letters are exactly the GE appliance system, so this is probably Sharp-built GE-style dating (ESTIMATE). getsupport.sharpusa.com = 200 (support portal); sharpusa.com warranty/registration paths 404.
