GFCI Tripping
Botswana:
Ive had a thought and that is - it's either the heater or the main board.
Here's I have developed that theory. The wiring and breaker were both replaced. Still happens. One of the pumps was replaced. Still happens. The other pump and the LEDs are not on when the spa is not in use, which is when it's tripping. That leaves the only other two options to be the heater and the main board, no? The tub heats and maintains temp fine, which then points me to the board...which is expensive. Are there any tests I can do on just the board? I supposed disconnecting everything and if it still trips? Would probably have to have the tub drained bc I can disconnect everything or else water would get crappy if it took like 2 weeks to trip..

It's driving me nuts.
At this point it seems like the only real options are 1) the pump that wasn't replaced 2) the board or 3) the heater (which is unlikely since it heats fine and maintains temp well). Am I off here? The tub has no additional accessories besides the LED lights. No OZONE, circ pump, Bluetooth, stereo or anything. Just the basic tub with LEDs (which work fine).

3) even though it heats fine it could still be the heater. Ohm tests on the heater are difficult. You will need the ohm reading of a new heater first. And the directions on how to ohm test your heater. This is done with power off. See if your dealer can help you here.
1) the pump that wasn't replaced, 2 speed main pump or aux? When your using the tub turn it on and off several times see if that initiates a trip.
2) I am leaning to board.

Tman, can you read my post right before this? Curious if my thought pattern is correct. I'm not 100% which was replaced. I know it's the one on the right side but not sure which it controls until I take side panels off.
The service man did go crazy pushing buttons to try to get it to trip..both heat up and down and jets on off continuously. Nothing acted up and the megger showed nothing over 0.11. he said it needed to be over 6.0 to trip the breaker, so it was far off

Sounds like it was the 2 speed main pump that was replaced. Thats good.

Yes, I went outside this morning and confirmed that. In my mind, the other pump causing the trip isn't logical since its never used outside of the tub being manually used. Is that a correct assumption?
Which leaves the heater and the main board as the likely culprits...
