The GFCI trips intermitantly on my spa. The Blower was unplugged and the GFCI worked. Another Blower was installed and the GFCI trips again. I say the GFCI works and there is still something wrong in the spa. The Dealer says my GFCI is old and needs better noise suppression. They want to replace it with a different brand, at my cost of course.
GFCI 220volt 50Amp Square D.
Thanks,
Paul
