My pool cleaner work fine up until today. In fact I ran through a cycle today and it worked fine. Now whenever I hit the button, the blue light blinks five times it starts to move and then just shuts off. I have reset it three times and it continues to do the same thing. When I press the start button on the control panel, the blue light starts blinking like it always did, and it actually starts to move but after the fifth blink it just shuts off. Of course it is five months past the two-year warranty. It is a Doheney Discovery S 200. Any ideas? Thanks
