• Symptoms: Circulation pump (heating pump) not turning, panel heat indicator not lit, panel
is flashing FL2.
Standard Troubleshooting Approach
Pull wire off flow
switch. Does the FL2
error message go
away?
Turn off power to hot
tub. Test flow switch
with ohmmeter for
continuity across
switch terminals (fig.
D-E). Does meter read
continuity (0Ω)?
Remove flow switch
and inspect for debris
interference. Remove
debris if present. Test
switch for continuity
(0Ω) when closed and
for infinite Ω when
open (fig. E). Does
switch operate cor-
rectly?
Install switch making
sure flow arrow points
in direction of flow
and switch doesn’t
bottom out in fitting
(fig. F). Retest system.
Is wire shorted?
Replace wire.
Make sure wire is not
shorted when in-
stalled on switch.
Replace flow switch.
