14.7 Panel Flashes FL1 or FL2
A ashing “FL1” display means the ow switch is
malfunctioning open, the lter cartridge is excessively dirty or
an “air lock” condition has occurred at the circulation pump
intake. A ashing “FL2” display means the ow switch is
malfunctioning closed. In either case, the spa heater will deactivate and
jets pump #1 may also deactivate. To correct condition perform the
following:
1. Verify water level is above all jets but below lowest pillow. Add water
if necessary.
2. Check for clogged or dirty lter cartridge (Sec. 12.1, page 36).
3. Purge “air lock” from circulation pump intake by removing lter
cartridge. Hold your garden hose over the lter cartridge wall tting
while using a rag as a seal around hose end. Ask a helper to turn
on water for 30 seconds, then turn off. Reinstall lter cartridge and
check spa (Sec. 12.1, page 36).
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 Jacuzzi dealer.
