SPA TROUBLE SHOOTING GUIDE

SPA NOT HEATING
* If the spas heater has failed, the majority of the time it will trip the GFCI breaker. If the 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 spa models diagnostic message
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 "heat mode" the spa is set in. Spa should be in standard mode.
5. Check the control panel for heater light indicator, see controls section of manual. If the indicator
is on, the spa should be heating. Wait a reasonable amount of time (approximately 1 hour) to
see if the water temperature is changing.
6. Check to make sure that the pump is primed and all slice valves are open.
7. Reset power to the spa at GFCI breaker.
8. If 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
protection. 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. It may be necessary to contact an electrician if your dealer
recommends doing so.
