So I just read in another post that the "flo" error code also reads pressure switch probs., and that the pressure switch has a dial or screw on top that you can adjust for sensitivity. Since my "flo" error code indicates that there is no pressure, could I or should I attempt to adjust the switch first?

I'd also like to add that, the GFCI was tripping and that was what I noticed before checking anything. I discovered the leaking pressure switch and replaced that. Now, the GFCI does not trip and everything but the heater works. The pressure switch had a lot of corrosion, (see pic above), I don't if that means anything other than that it was wet and that caused the corrosion.

Thanks for all the replies. I replaced the switch but I'm getting a "flo" error message. According to the manual, this indicates that there is no pressure sensed and the unit automatically shuts down the heater, (everything works but the heater). What should I check at this point?

Thanks guys, here's the leaky part. Is this a pressure switch?

I've got a leak at a part that screws into the horizontal pipe at the bottom of the board? I have a pic but can't figure out how to post. The part is about the size of a spark plug with two leads at the top. Not sure if I can replace the part, (it screws in) or if I have to replace the whole board, It's says "spabulilders scmp1xxxx..." Any help posting pics would be great, thanks
