8.1C No Heat or Not Enough Heat (All Models)
• Symptoms: Low speed pump 1 or circulation pump (heating pump) not turning, panel heat
indicator not lit, panel is ashing FL1.
Standard Troubleshooting Approach
This applies to 2011-2013 J300 Models not 2014+
Is there correct voltage coming to the
hot tub at TB1? Test point 1 and 2. See
page 50-53
240 VAC, ± 10%, or (120 VAC,
± 10% for convertible models).
Put hot tub in standard ltration mode
(page 7). Set temperature high
enough to initiate a heat call.
J-LX, J300, J200 (with Circ Pump): Is
voltage from circuit board to circulation
pump ok? Test point 14 and 15. (See
page 50-53).
J200 (without Circ Pump): Is voltage
from circuit board to low speed pump
1 ok? Test point 5 and 6. (See page
50-53)
Note: Refer to voltage and current
charts on appendix pages 43-45
for expected voltage/current readings.
