panel Flashes Fl1 or Fl2

A flashing "FL1" display means the flow switch is
malfunctioning open, the 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. 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 filter cartridge (sec. 12.1, page 30).
3. Purge "air lock" from circulation pump intake by removing filter
cartridge. Hold your garden hose over the filter cartridge wall fitting
while using a rag as a seal around hose end. Ask a helper to turn
on water for 30 seconds, then turn off. Reinstall filter cartridge and
check spa (sec. 12.1, page 30).
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.
