Just received the Domino XL from the reconditioned sale. I went through the process for getting it ready to use and when I turned it on it would only stay on for about 2 seconds. I turned it off and tried again but the same thing. I unplugged it from the extension cord and then plugged it into the outlet - same thing. Is there something that I am missing or is it just defective? I have started the return process for repair.
