• 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. Check for proper water level. Water should be 1” below lowest pillow.
2. Check for clogged/excessively dirty circulation pump filter cartridge
(control panel side). See section 11.1, Page 30.
3. Purge “air lock” from circulation pump intake by removing its filter
cartridge (control panel side). Place your garden hose over the heater
return wall fitting near the underwater spa light (sec. 8.2, page 15).
Turn-on water for 30 seconds, then turn off. Reinstall filter cartridge and
check spa. See section 11.1, page 30.
3. If problem persists, contact your authorized dealer.
