How to read the serial

era not stated formatUNSOURCED

Documented but not evaluated by the decoder: no pattern (no date encoded, or format unknown).

Trap: mieleusa.com (403 to curl, 200 in a browser) only publishes where the data tag is (plate-finder). Miele does not publish a date code; tab-tv.com says 'the date of manufacture is known only to Miele' and gizmocleaning.com's 'first three digits = year+week' claim is self-contradictory (its example '181' = week 18 of 2011). Ship as 'contact Miele with the serial' until a Miele document appears.

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

No online serial lookup was found for Miele in our research. The manufacturer's customer service line, the installer's invoice, or a printed date on the plate are the remaining authorities.
