Hi, I am newbie. I kept the jacuzzi in operation during heavy rain. Since then, when I switch on the Jacuzzi, the breaker trips. I replace the fuse (SC-30) from the Balboa board (H700), I disconnected all the pump and still the same problem. Therefore I believe that the board has to be replaced? Anyone can confirm? Is there anyway to check if it is the board or the Power transformer? If I change the board (with a more recent model most probably), do I need to change the controller as well? Many thanks
