FLOW-RELATED CHECKS
Check filters for possible blockage. Try cleaning or replacing filters (especially if the 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 the 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.
