Your thermostat has failed.  It appears Delong does not sell the part. http://www.ereplacementparts.com/delonghi-kbx1510-kettle-parts-c-122345_122346_122827.html

You could try taking the bottom off and see if it can be opened.  Then post a couple of pictures and we can see if we can suggest a repair.
