Lights Tripping GFCI Problem

[CarlD]

Have you replaced the GFCI, to ensure it's not failing?

The only other thing I can think of is there aren't enought minerals in the water to allow it to pass much of a current, so there isn't enough to trip the GFCI until the level is 100%. Or you are getting a capacitor action that discharges and trips it.

But a GFCI should trip at the slightest imbalance in the poles...but it's 12v right?.......

Carl,
Sorry for the delay in this reply, i've been unable lately to check the forum. Yes, i replaced the GFCI and eliminated it as the problem. Pool Guy also did the same thing and found no problem with it. The system is 120v. Its still not fixed yet, but the pool guy is going to replace the light assembly and bulb.
