Welcome to our forum.
I had trouble with GFCI Breaker tripping right after replacing a circulation pump. Swore it was the new pump but ended up being the breaker itself. Replaced it and know more troubles.
From heater terminal to the outside housing of the heater ( the tube) was 0/OL when measured. Is that what you were refering to?
Hmm..so no way to do further diagnosing on this? I suppose disconnecting the heater but I'd probably have to have it disconnected for more than a month to prove it's the heater since it only trips about every 2 weeks. The heater looks good. I have pictures that I posted to another thread, but no signs of moisture or burn marks. I suppose inside of the heater could be leaking? And that's really impossible to know, correct?
Thanks...so it seems like I'd have to remove the heater to do the testing if I get one of these. Was hoping for a test without having to drain/disassemble
