Troubleshooting - Jacuzzi J-300 series Montageanweisung Und Bedienung Und Wartung

The panel shows SN1
Open sensor (heater is deactivated) or shorted sensor (spa is de-
activated). The upper-limit temperature sensor is not functioning.
I
Contact an authorized service center.
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
Check that the water level is about 3 cm from the lowest
headrest. 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 working, turn the main switch off
and on to prime it again.
I
If problem persists, contact your authorized dealer.
The panel shows COL
The temperature has dropped 11°C below the set temperature.
The pump and heater have been activated to bring the tem-
perature to within 8 °C of the set temperature.
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. Main pump will operate to circulate
warm water through the plumbing until the spa is out of danger.
N.B.: "ICE" will only appear when the spa is in Economy mode.
Panel displays - - -
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 servicecenter.
Panel Displays CF
The clean filter timer has expired. The spa filters need to be
cleaned or replaced. The message will flash between "CF" and
the water temperature. The countdown timer for the Change
Filter feature needs to be reset. New filters can be purchased
from a local Jacuzzi dealer.

If the spa is not working the way it should, please first review
all the installation and operating instructions in this manual and

isfied it is working properly, please follow the troubleshoot-
