G.F.C.I. Troubleshooting
IF CORRECT WIRING IS VERIFIED
Check to see if the proper G.F.C.I. is installed.UÊ
Check the label in the system box near TB1 to determine UÊ
the maximum amperage draw for the system.
Be sure the G.F.C.I. is rated for more amperage than the UÊ
system will draw.
For a 240 V dedicated system, a 2-pole G.F.C.I. with no UÊ
load neutral is acceptable.
For a 120/240 V system, the G.F.C.I. must include a load UÊ
neutral out.
If the white load neutral wire is routed from the G.F.C.I. UÊ
neutral bar directly to TB1 in the system box, then the
G.F.C.I. will trip when a 120 V device is activated.
For a detailed wiring checklist, please review the UÊ
previous segment of this manual on proper G.F.C.I. wiring
or the G.F.C.I. manufacturer’s instructions.
If the wiring is correct and the G.F.C.I. will not reset, then UÊ
unplug the pump and try to reset the G.F.C.I.
If the G.F.C.I. trips again, then unplug the blower and UÊ
reset the G.F.C.I.. If the G.F.C.I. continues to trip, then do
the same procedure for the ozone generator.
If the G.F.C.I. stops tripping after you unplugged one of UÊ
the spa’s components, turn off the power to the spa then
plug in each component except the one that tripped the
G.F.C.I.
Power up the system. If the G.F.C.I. no longer trips, UÊ
then you have correctly identified the problem.
Repair or replace the component as instructed by
the spa manufacturer.
If you have unplugged all of the spa’s components and UÊ
the G.F.C.I. still doesn’t reset, then the problem is most
likely a ground fault in the heater.
TO DISCONNECT THE HEATER
First, turn off the main circuit breaker, then remove both UÊ
heater straps or wires from the system heater output,
not the heater itself.
After restoring the power, try to reset the G.F.C.I. again. UÊ
If it no longer trips after the system calls for heat, then
replace the heater.
If the G.F.C.I. still trips, look for pinched or shorted UÊ
wires at the transformer. Make sure that the screws
that attach the transformer to the system box
have not pinched or damaged the insulation of the
transformer wires.
If the transformer wires are undamaged, check for any UÊ
other pinched wires. Refer to the wiring diagram to
verify the correct wiring of the control system.
If everything looks to be in perfect working order, then UÊ
the G.F.C.I. may be defective.
Keep in mind that a majority of G.F.C.I. tripping problems can be attributed to incorrect wiring. G.F.C.I. troubleshooting usually finds
the problem.

WARNING: THE OWNER SHOULD TEST AND
RESET THE G.F.C.I. ON A REGULAR BASIS TO
VERIFY ITS FUNCTION.
