FLOW-RELATED CHECKS
Check filters for possible blockage. Try cleaning or replacing filters (especially if spa is equipped
with 24 hour circulation pump). Check for low water level, suction flow restrictions, closed valves,
trapped air, too many closed jets and pump prime.
On some systems even when spa is shut down, some equipment may occasionally turn on to
continue monitoring temperature or if freeze protection is needed.
