Thanks to Hurricane Sandy we lost power for about 20 hours. Luckily no freezing yet. When I checked the spa it had the Watch Dog error code. The dealer suggested I trip the gfi breaker, leave for 15 minutes then turn on the breaker. Here's the problem... When I push the "test" button on the breaker, it does not trip the breaker. The breaker is a 60 amp dual pole gfi breaker made by Square D. I did turn off the power at the breaker by flipping the switch to off and after 30 minutes turned it on again with the same error code. I also tried a reset by turning off the power at the house panel but that didnt work either. Is it possible that I have a faulty gfi breaker because I cannot trip it by pushing the test button? Would that possible be causing the error code? Any suggestions very much welcomed.
