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 the 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 or service organization.
PUMP(S) DO NOT OPERATE
1. Press the "Jets" button on your control panel.
If you hear the pumps trying to operate:
A. Check that all the slice valves are open.
B. Pump may need to be primed.
Refer to Installation Instructions section. If you do not hear anything from the pump, contact
your local Master Spas dealer or service organization.
POOR JET PERFORMANCE
1. Make sure pump is operating.
2. Check that the water level is adequate (at least to minimum safe water level on sticker located
near filter.)
3. Make sure the jets are open and the air controls are open.
Refer to Glossary of Swim Spa Technology section.
