1 Under normal conditions the hot tub GFCI circuit breakers should should be checked using the TEST Button, and then reset normally. 2  Typically a hot tub GFI Breaker will last for several years under ideal conditions. I filled the tub with fresh water and hit the breaker. 2  You can hear electrical noise in breaker like it is shorting, then breaker kicks off. 3  Even if there was a short in the spa, the breaker should just kickoff without the noise. 4  It sounds like two wires arcing, there is no smell and the breaker is not melted.
Most hot tubs, when first filled or refilled, take about 12-24 hours to heat up. In some cases, outdoor spas may take up to 2 days to heat up in the summer. If youâre hot tub is taking longer than this to heat up, there may be something wrong with the unit and youâll want to have it checked out.
