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.
Resolved Question: I have a Leisure bay G Series Spa (45GI) - It does not heat up past 82 degrees-keeps showing on the readout OH (Overheat Protection) or FLO (Filter clogged or Pressure Switch).I have done all the trouble shooting suggestions-I think it maybe the pressure switch.ry running the spa for a while without the filter in it and see if it does the same thing. Customer: have run tub for last 2 hours without the filter-display still flashing COOL-FLO - 55 DEGREES-that is as high as the TEMP has gotten-the tub has been on for 24 hours.
