Open or shorted sensor (heater disabled). The temperature
sensor is not functioning. Your authorized dealer must repair this.
13.5 Panel displays FL1 or FL2
A flashing “FL1” display means the flow switch is
malfunctioning open, the circulation pump’s filter cartridge is
excessively dirty, or an “air lock” condition has occurred at the
circulation pump intake. A flashing “FL2” display means the
flow switch is malfunctioning closed.
This error will cause the heater to deactivate. The main •
pump #1 may also deactivate.
This problem is caused by an interruption in water flow from an •
excessively dirty filter cartridge, an “air lock” condition at the pump
intake, or by a malfunctioning flow switch.
To Correct Condition:
1. Verify water level is above all jets and below lowest pillow.
Add water if necessary.
2. Check for clogged/excessively dirty filter cartridge. See
Section 11.1 (pages 31-32).
3. Purge “air lock” from circulation pump intake by removing the filter
cartridge. Hold your garden hose over the filter wall fitting (with
grate) using a rag as a seal around hose end, then ask a helper to
turn on water for 30 seconds, then turn off. Reinstall filter cartridge
and check spa. See Section 11.1 (pages 31-32).
4. If the circulation pump is not running, turn power off at the main
breaker, then turn power back on. This will reset the circulation pump
priming cycle. Once the pump is primed, the error should clear.
5. If problem persists, contact your authorized dealer.

Note: During cold periods, you may consider increasing the number of
filtration cycles.
