560. Support: GFCI tripping only after the system has been running for sometime.

With the GFCI tripping only after the system has been running for sometime, the problem can be the heater, water leaking from the heater, water infiltration onto the circuit board or water infiltration on other components (pump, blower, etc), loose wire connections, overheat on the wires or cords, a problem with the circuit board or the GFCI is sensitive. Check all the items mentioned above to see if there is a problem. You can try to disconnect other component cords for the day that has nothing to do with the heating. Like a pump or pumps (that does not circulate water through the heater), blower, ozone and/or light. Then power the system back up to allow the spa to run with those components disconnected. If the GFCI breaker does not trip, then the problem can be one of those components that were disconnected. You will then plug in only one component that was originally disconnected for the day to see if that component will cause the GFCI breaker to trip within the day. If it still does not trip the GFCI breaker, add another component, and so on. If the GFCI breaker still trips with those components disconnected, then the next step is to carefully disconnect both heater cables or straps so there is no power to the heater. Make sure the power is off when performing this, and make sure to follow the heater removal instructions to aviod any damages to the heater. If the GFCI still trips, the problem may be the circuit board, the pump, water infiltration, loose wires or a sensitive GFCI breaker. If the GFCI breaker does not trip after disconnection of the heater, the problem can be the heater and can still be a sensitive GFCI breaker. NOTE: Do not consider a reading between Line 1 and Neutral as a short. The reading should be between 10 to 12 ohms, which is the resistance reading of the transformer. This is not a short. Let us know you findings.
