Well, I started to top off my spa and forgot about it. 9 hours later, things we're pretty wet. This happend 4 days ago. Now the GFCI trips when the heater turns on. Pump and blower work fine.

I tried using a hair dryer last night and still no luck. I am worried to let it sit to much longer as it is getting cold here in central Ohio.

Through reading this forum, a few have mentioned some test to do when something like this happens. Could someone give me a little guidence on what to check and how. I have a small Multimeter that will do resistance to 4M ohm.

This is a Cal Spa unit from a while back, late 80's maybe.

Thanks for any help,
Jeremie

I have been doing some more forum searching and noticed in another post that someone said even if you have the temperature on "OFF" the heater would still draw juice. If this is correct then I need to clarify the above.

Everything runs fine when the temp is in OFF. As I turn it to warm, and you hit that spot that turns the heater on, that is when the GFCI trips. So could it be the part that it labeled on the control box as SWITCH or FLOW (Not sure which one, I am going by memory).

Thanks,

I thought I would add a few pictures. Maybe these can help someone help me. Any help would be greatly appreciated.

Thanks,

Am I looking at 2 seperate heaters?

Swine,

Looks to me like the second (bottom) picture is of a current collector, not a heater. The heater looks to be behind the control. IMO

The test is that of the heater element, and you do so by removing both wires and isolating them (tape them off) so they don't come into contact with anything. Then try adjusting the temperature. If the breaker now holds, your element is in need of replacement.

I would wager that the overfill and the heater going out (if that is the case) happened at the same time by chance.

Wow, a second and seperate current collector.... alrighty:?

But anyway- Listen to Charger- remove the cover of the control box, and remove BOTH heater leads. You can't unplug the heater like the other components. Good luck, let us know the results!

Yea I found it strange to, but if I had to wager a guess, It would be that the spa had been upgraded to the spa pack at one point in it's life. Prolly had a really old style heater and control system at one point and they just left the collector in. I would guess that since the really old style used 2 collectors, one was removed and the spa pack spliced into it's place. Be really easy seeing as it has the proper type of nuts on the collector, same as a heater tube.
