Will not start up??

This product worked fine for about 2 months then all the sudden just quit on me. When I unplug the unit and plug it back in the indicator with the three squiggly lines blinks about 3 times then goes off. I tried resetting by holding down the power button, but when I press start the green light comes on and does nothing. I have tried cleaning the filters with all the brushes that came with it and still nothing. I plug it in, the red light blinks 3 times then I press start and nothing? Any help would be....well.....helpful, thanks.
