Why would hoover carpet cleaner make a loud noise, start smoking and now won't come on.

So how do you fix that? Mine did the same. Used it first time out of the box and it worked great. Stopped to refill the clean and empty the dirty water. When I started back up it worked for about 5 seconds and then cut off (as if someone unplugged it). Checked the outlets, that wasn't the problem. Sent it to the repair place that Hoover customer service directed. They kept it a week and the. Called to say it worked perfectly in their shop. I brought it home, and it worked great again... Then about halfway through the second tank of water the sound began to change (as of the motor was overheating and struggling). I cut it off, went back to it after time to cool, and NOTHING.
