My pool place exchanged the power supply yesterday for a new one. So today, I'm running it, and the rain starts again! I sure hope this one doesn't fail, too! Anybody leave their's out in a hard downpour and it be OK? If so, did u do anything special, like not run it for days? There is no way to take the cover off to dry it out. It looks like the only way it can get water in it is from underneath. Unfortunately, it was sitting on my patio, where water tends to collect in the channels between the bricks that the previous homeowner put down.
