Jacuzzi J-LXK Installation Manual And Use & Maintenance page 35

The panel shows SN2
Open or shorted sensor (heater disabled). The temperature
sensor is not functioning.
I
Contact an authorized service center.
The panel displays FL1 or FL2
If the message "FL1" is flashing on the display, it means that
the pressure switch is not working properly, or that the filter
is very dirty, or that there is an air lock in the circulation pump.
A flashing "FL2" display means the flow switch is malfunc-
tioning closed.
This error will cause the heater to deactivate. The main pump 1
may also deactivate.
- To correct the situation:
I
Verify water level is above all jets but below lowest pillow. Add
water if necessary.
I
Check for clogged/excessively dirty filter cartridge.
I
Vent the "air lock" from the circulation pump by removing the
filter cartridge and inserting a (garden) hose in the cartridge
housing. Place a rag around it in order to "seal" the opening con-
nected to the pump. Turn on the water for about 30 seconds. Turn
it off and reinstall the cartridge. Check the spa operation.
I
If the circulation pump is not running, turn power off at the
main breaker, then turn power back on. This will reset the cir-
culation pump priming cycle. Once the pump is primed, the er-
ror should clear.
I
If problem persists, contact your authorized dealer.
The panel shows COL
The temperature has dropped 11°C below the set temperature.
Pump 1 (or the circulation pump, if included) and the heater
are activated to bring the temperature to 8 C° from the set tem-
perature.
I
No corrective action is required.
N.B.: during cold periods, increase the number of filtration cycles.
"COL" will only appear when the spa is in Economy mode.
The panel shows ICE
Freeze Protection - A potential freeze condition has been de-
tected.
I
No operation is required. The main pump (or the circulation
pump, if included) and the heater will activate to circulate warm
water through the plumbing until the pool is out of danger.
N.B.: "ICE" will only appear when the spa is in Economy mode.
Panel displays - - -
Water temperature is above acceptable limits.
Do not get into the spa, the water may be too hot.
The safety software has been activated and the spa is deacti-
vated; a problem has been detected which may damage the
spa or its components.
I
Contact an authorized service center.
