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 water set temperature at control panel to make sure it is set to desired temperature,
above the current water temperature.
2.
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.
3.
Check the control panel for heat indicator. If heat indication is on, wait a reasonable amount of
time (at least 1 hour) to see if the water temperature is rising.
4.
If heat indicator does not remain on, the system should be displaying a message indicating why
it can’t heat. Check the control panel for diagnostic messages. Refer to Spa Control Section
titled System Related Messages. Follow steps to alleviate message.
5.
Check the control panel for light indicator. Wait a reasonable amount of time (at least 1 hour)
to see if the water temperature is rising.
6.
Reset power to the swim spa at GFCI breaker.
7.
If swim spa is still not heating, contact your local Master Spas dealer for service.
GFCI IS TRIPPING
A ground fault circuit interrupter (GFCI) is required by the National Electrical Code for your protec-
tion. The tripping of the GFCI may be caused by a component on the swim spa or by an electri-
cal problem. Electrical problems include but are not limited to, a faulty GFCI breaker, swim spa
component, power fluctuations, and/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 swim spa. It may be necessary to contact an electrician if your Master Spas
dealer recommends doing so.
