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 (i.e. any leaves or debris pulled against suc tion
fittings in bottom of spa shell), closed valves, too many closed jets and pump prime/air locked pump
(see initial spa setup for instruction on relieving pump air lock).
On some systems, even when spa is shut down by an error condition, some equipment may
occasionally turn on to continue monitoring the temperature or if freeze protection is needed.
