14.6 Panel Flashes FL1 or FL2

A flashing "FL1" display means the flow switch is malfunc-
tioning 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 26).
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 26).
4. If problem persists, contact your authorized Jacuzzi dealer.
