Won't heat up and power light doesn't come on

The third time I used it I noticed the light flicker on and off but it was still working. When it was empty I cut it off let it cool down and refilled it. However this time the light did not come back on and it did not heat up. How can I fix it or where can I take it to get it fixed. I live in Virginia Beach, Va. I hope I can do it myself for I'm disabled on a very limited income. Thank you
