No Heat
1. Dirty fi lter: Clean the fi lter per the instructions provided in the
Maintenance section of this manual. If the fi lter is more than two months
old, replace it. After cleaning or replacing the fi lter, cover the spa, turn
the temperature set point all the way up, and leave the spa for 24 hours.
If the spa still will not heat, contact the manufacturer for instructions.
2. No circulation, water pump air bound: Unplug the power pack from
the electrical outlet. Bleed air from the fi lter tank by turning the bleed
fi tting on the top of the fi lter tank counter-clockwise. After one minute,
or when water drips from the fi tting, close the bleed fi tting and plug in. If
the water pump still does not pump water, contact the manufacturer for
instructions.
If the water pump becomes air bound again, check the o-ring on the
top of the fi lter tank. Refer to the fi lter changing instructions in the
Maintenance section of this manual. Replace the o-ring if necessary.
3. Bad power pack: Ensure power is available to the spa. Check the circuit
breaker at the main electrical panel. Connect another electrical appliance
to the plug used for the spa. If power is available to the spa, test the GFCI
using the instructions supplied in the Maintenance section. If the GFCI
is working properly and the power pack does not function, then the
power pack is bad. If the GFCI is not working properly, do not use the
spa. Immediately contact the manufacturer for instructions.
4. In some situations, the numerical temperature display may read ‘OH’
(overheat) and the spa will not heat until reset. To fi x this problem,
please use the following procedure:
A. If the spa water is still warm (over 104°F / 40°C), unplug the
power pack and let the water cool to below 104°F / 40°C. (Use a
thermometer to verify the temperature.)
B. Plug the power pack back in and press the small reset button directly
below the temperature display.  is will clear the ‘OH’ message and
the spa will resume normal operations.
Should this problem occur repeatedly, please call our customer support
