8.1D No Heat or Not Enough Heat (All Models)
• Symptoms: Low speed pump 1 or circulation pump (heating pump) is turning, panel heat
indicator not lit, panel is ashing FL1.
Standard Troubleshooting Approach
Is the low speed pump
or circulation pump (Heat
Pump) moving water?
Verify hot tub is in
standard ltration mode
(page 7) then perform
step below.
Remove switch wires
from board. Increase set
temperature to initiate a
heat call, then jumper ow
switch wires together (Fig.
9-10). Does heat indicator
appear and FL1 error
message disappear?
Test ow or pressure
switch with ohmmeter for
continuity (0Ω) across
switch terminals (Fig. 11)
Does meter read continuity
(0Ω) with pump on?
Clean connectors between
ow cable and switch.
1. Remove lter and
allow air to bleed
out of cartridge.
2. Check for proper
water level.
3. Check for clogged/
excessively dirty
lter.
4. Check for blockage
at lter wall tting.
5. Check for sticking
weir.
6. Is pump moving
water?
Remove ow or pressure
switch connector from
circuit board test point
23 (Fig. 10). Place
jumper across exposed
connector pins*. Does
heat indicator appear
and FL1 error message
disappear?
Repair or replace ow or
pressure sensor cable.
Remove ow or pressure
switch and inspect
for debris blockage.
Remove blockage or
replace switch.
Re-install ow or
pressure switch. Install
ow switch with arrow
pointing in direction of
ow. Make sure magnet
arm doesn’t bottom out
in tting (Fig. 12).
