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 "heating mode" the spa is set in. Heat mode should be in "std".
5.) Check the control panel for heater light indicator and / or thermometer
icon. If the light is on or the indicator icon is moving, 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
The Ground Fault Circuit Interrupter (GFCI) is required, by NEC code
(National Electrician Code), for your protection.The tripping of the GFCI
may be caused by a component on the spa or by an electrical problem. Such
electrical problems include, but are not limited to, a faulty GFCI breaker,
power fluctuations, or a miswire. It may be necessary to contact an electrician
if your local dealer recommends doing so.
