I have a newer 110V SPA with new ACC components. After I use the SPA, with high speed jets on, I press the SET button which then is supposed to turn the pump to low speed jets and turn the FILTER light on, to filter for 30 sec and then go to the ECON mode. Instead the topside display resets, blinks on/off and changes the time to the factory default of 12:00, and sometimes changes the heat calibration and the 110v/220v preset. If there's a short in the system why doesn't the GFI trip? What's going on? Thanks, Dave

Maybe a better question would be how soon do I need to fix this. I have an outbuilding served by a 50A 2-pole breaker in my main panel. It is connected to my house by 2 overhead wires on a messenger cable with the messenger being the ground. The outbuilding has another outbuilding connected to it by a 8 foot breezeway (roof only) and the 2nd outbuilding only has overhead lights but I would like to add some receptacles. The first outbuilding has one receptacle, overhead lighting, and some outdoor lighting. To further complicate things, The sub panel also powers my pump house which is about 100' away on the other side of a creek. The pump house is connected to the sub panel by 12/3 UF cable run underground and under the creek. The pump house itself has a 4-space sub panel that I installed mostly so I could switch the pump off without killing the pump house lights. The only ground rod is at the house at the service entrance. It appears that now, this should be all 4 wire runs. All of this wiring was done in the '70s so it may have been ok then. Eventually, I want to replace the overhead run with underground cable and will run 4-wire cable then. Should I make this a higher priority to bring it up to current standards? What about the barely attached 2nd outbuilding? Does it need its own ground rod? And does the pump house need a ground rod? It already has a 4 wire cable running to it. Any guidance I could get would be appreciated. Thanks.
