Where can I find the serial number on my De’Longhi product?

The serial number is typically embossed on the underside of your machine. It will consist of five numbers, for example 50424. You may need a good light source to see it, but it is printed on every single one of our products. On a portable air conditioner it may consist of 8 numbers, and if this is the case it will often be found on the top right hand corner of the rating label.
