I just had the same exact issue yesterday. Mine was electronic related. Not the housing - me. This had never happened before. It was the 4th of July, went on a 2 tanker, strobes had issues firing all day, I finally worked out the strobe issue when i returne home and suddenly - my leak detector began to blink. No water got inside the housing. No chance to contact anyone being that it was the 4th of July. And when I tried to look on wet pixel, it said, "down for repair". My moon was obviously not in my 7th house and Jupiter was not aligned with Mars. I left the battery out overnight and this morning it was fine. Oddly, my Subal was purchased at Reef Photo as well... I'm betting Mr. Canon is somehow behind this... (Just kidding Ryan).
