SWIM SPA TROUBLE SHOOTING GUIDE
Note: For wiring outside of U.S. and Canada, GFCI may be referred to as a RCD (residual current
device). Be sure all local electrical codes are followed.
SWIM SPA NOT HEATING
If the swim spas heater has failed, the majority of the time it will trip the GFCI breaker. If the swim
spa is not heating and has not tripped the breaker, please follow these steps:
1. Check the control panel for diagnostic messages. Refer to your swim spa models diagnostic mes-
sage area in previous sections. Follow steps to alleviate message.
2. Check water set temperature at control panel.
3. Check for dirty filters. Clean if necessary.
4. Check the "heat mode" that the swim spa is set in. The swim spa should be set in the standard
mode or ready mode depending on the model.
5. Check the control panel for light indicator. Wait a reasonable amount of time (approximately 1
hour) to see if the water temperature is rising.
6. Check to make sure that the pump is primed and all slice valves are open.
7. Reset power to the swim spa at GFCI breaker.
8. If swim spa is still not heating, contact your dealer for service.
GFCI IS TRIPPING
A ground fault circuit interrupter (GFCI) is required by the National Electrical Code for your pro-
tection. The tripping of the GFCI may be caused by a component on the spa or by an electrical
problem. Electrical problems include but are not limited to, a faulty GFCI breaker, spa component,
power fluctuations, or improper wiring. If this is a new electrical service and GFCI installation, an
instantly tripping GFCI may likely be caused by improper wiring of the load neutral from the GFCI
to the spa. It may be necessary to contact an electrician if your dealer recommends doing so.
