Good morning! My little helper has quit working. Nothing in the impeller or in the way of the tracks or brush. Took off the cover and no debris in there at all. Impeller turns for a second, tracks and brush activated and then everything stops. The manual says to clear cleaning program by pushing the button 4 times. I've done that many times - the lights go on under the "1", "2" and "3" and then blank. The power remains on. Unplugged everything overnight, still no more than the initial cycle. Any ideas? Sent an email to Maytronics, only a year old.
