13.5 Panel Flashes FL1 or FL2 (Spas With Circulation
Pump Option)
A flashing “FL1” display means the flow switch is malfunctioning
open, the circulation pump filter cartridge 1 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 1" below lowest pillow. Add water if necessary.
2. Check for clogged or excessively dirty filter cartridges (Section 11.1,
page 30)
3. Purge “air lock” from circulation pump intake by removing filter
cartridge 1 (page 30). Hold your garden hose over the filter cartridge
1 wall fitting (with grate) 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 1 and check spa (Section 11.1, 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 Sundance dealer.
