SPA TROUBLESHOOTING 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.
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, 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 spa. It may be necessary to contact an electrician if your Master Spas dealer
recommends doing so.
NOTHING ON THE SPA OPERATES
1. Check the control panel display for any messages. If there is a message, refer to the diagnostic
section on that spa model. There you will find the meaning of the message and what action is
to be taken.
2. If there is no message on the control panel and the control panel is completely dark (off), try to
reset the GFCI breaker.
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 set water 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 spa is set in. The spa should be set in the Standard Mode or
Ready Mode depending on the model. If placed in an Economy or Rest type mode, it changes
the way the system heats and will primarily only heat during user programmed durations. See
Spa Control section for further details.
3. Check the control panel for heat indicator. If heat indicator is on, wait a reasonable amount
of time (at least 1 hour for 240V systems or 3-4 hours for 120V systems) 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 the message.
5. Check the control panel for light indicator. If the heat indicator is on, wait a reasonable
amount of time (at least 1 hour for 240V systems or 3-4 hours for 120V systems) to see if the
water temperature is rising.
6. Reset power to the spa at GFCI breaker.
7. If spa is still not heating, contact your Master Spas dealer or service organization.
DO NOT DIVE. DO NOT DIVE.
The GFCI should be located in a weather proof box close to the spa,
but no closer than 5 ft.
If the spa does not respond, or the GFCI breaker continues to trip,
contact your Master Spas dealer or service organization.
