Not sure it this is your problem, but I had a similar issue with a GFCI circuit failing. Don't ask me why, but I was told (and it was true) that me electrical heating element in my water heater had been shorted out. This is caused by turning on the element without water in the tank. I pulled the cap off the back off of the element, disconnected the two wires, wrapped each with electrical tape, and tried the GFCI circuit again... and VIOLA! I subsequently replaced the heating element with a new one (they are not expensive) and life had been grand ever since.

As I said, I and not sure this is YOUR issue, but its an easy way to ensure it's not. Happy hunting!
