RUN PMPS PURG AIR Priming Mode
Each time the spa is powered up, it will
enter Priming Mode. The purpose of
Priming Mode is to allow the user to run
each pump and manually verify that the
pumps are primed (air is purged) and
water is owing. This typically requires
observing the output of each pump
separately, and is generally not possible
in normal operation.
Priming Mode lasts 4 minutes, but
you can exit it earlier by pressing
any Temp button. The heater is not
allowed to run during Priming Mode.
NOTE: If your spa has a Circ Pump,
it will turn on with Jets 1 in Priming
Mode. The Circ Pump will run by itself
when Priming Mode is exited.
---F - ---C Water Temperature Is Unknown
After the pump has been running for
1 minute, the temperature will be
displayed.
None
42F TOO COLD Too Cold - Freeze Protection
A potential freeze condition has been
detected, or the Aux Freeze Switch has
closed, and all pumps and blower are
activated. All pumps and blower are ON
for at least 4 minutes after the potential
freeze condition has ended, or when
the aux freeze switch opens. In some
cases, pumps may turn on and off and
the heater may operate during Freeze
Protection.
None.
WATR TOO HOT Water is Too Hot
One of the water temp sensors has
detected spa water temp 43.5°C (110°F)
and spa functions are disabled.
None. System will auto reset when
the spa water temp is below 42°C
(108°F ). Check for extended pump
operation or high ambient temp.
SFTY TRIP ---- Safety Trip - Pump Suction
Blockage
The Safety Trip error message indicates
that the vacuum switch has closed. This
occurs when there has been a suction
problem or a possible entrapment
situation avoided. (Note: not all spas
have this feature.)
Drain or lter may be covered,
creating a blockage. Clear the
blockage and reset by pressing any
button on the topside panel.
HTR FLOW LOSS ---- Heater Flow Is Reduced
There may not be enough water ow
through the heater to carry the heat
away from the heating element.

restrictions, closed valves, trapped
air, too many closed jets and pump
prime. Heater start up will begin
again after about 1 minute.
HTR FLOW FAIL ---- Heater Flow is Reduced
There is not enough water ow through
the heater to carry the heat away from
the heating element and the heater has
