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 spa diagnostic
message area in previous sections.
Follow steps to alleviate message.
2.) Check water set temperature at control panel.
3.) Check for dirty filter. 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. If the light 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.
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.
