when the spa water temp is below 108°F (42.2°C). Check for extended pump operaon or high ambient temp.
Heater-Related
The water flow is low – M016
There may not be enough water flow through the heater to carry the heat away from the heang element. Heater start up will
begin again aer about 1 min. See “Flow Related Checks” below.

Flow-Related Checks
Check for low water level, sucon flow restricons, closed valves, trapped air, too many closed jets and pump prime. On some
systems, even when spa is shut down by an error condion, some equipment may occasionally turn on to connue monitoring
temperature or if freeze protecon is needed.
