Ive bought the steam iron on the 8 Sept 2016 & started using it on the 15Sept 2016 the very 1st day of use the steam iron has stopped working. I need to be refunded by Rowenta

you sure on the model number as it is not in

suggest re checking the reference number as shown on the web page at rowenta it may be different and searching for it in the web page as I am having hard time finding anything for DW1040

depends on how old it is, try to rinse it with a water and vinegar solution, this might help

try it in another power point , otherwise have it repaired at a service center . not suitable for home repair.

Tap water contains minerals/chemicals, whether it's from a well, or from a city source. When water is heated to steaming, these minerals, precipitate out of the water and form deposits. Use some vinegar. The mild acid will help loosen the deposits... and from now on use distilled water.

Have you tried a descale ?

what is exact problem

Seems silly... but is it plugged in to a live outlet? Does it have water?

I never saw an iron with a retractable cord . The cover would have to be large enough to accomodate the cord and the heat from the iron could melt the cord. Are you sure it supposed to work like that?
