POWER & GROUND CHECKGFCI Trips!
1• Verify if the GFCI is properly
connected.
2• If it is not, verify the GFCI wiring
diagram and reconnect it.
If the equipment is connected but nothing seems to work, the power supply
must be defective. Perform the following:
Note that in new installations, GFCI trippings due to miswiring are very common.
If the breaker is properly wired, GFCI trippings can occur when the total amount of current
drawn by the spa exceeds the rating of the breaker. Such an occurrence, however, is very
unlikely since each output of the spa pack is individually fused and fuses will blow before the
GFCI trips.
A current leak to the ground will also make the GFCI trip. If one of the components is faulty
and there is a leak of more than 5 mA, the GFCI will trip to prevent electrocution.
Several different models of GFCIs are available on the market. Note that our illustrations are
generic.
3• If the GFCI is properly connected but
still tripping, disconnect all outputs,
including the two wires of the heater &
the light cord.
4• If the GFCI still trips, replace the
transformer.
5• If the GFCI still trips even after the
transformer has been replaced:
a- Disconnect the power input wires.
If the GFCI still trips, the cable must
be defective.
Call an electrician!
b- If the GFCI stops tripping, replace it.
c- If the GFCI is still tripping, replace
the board referring to the "How to
Replace the Board" section of this
manual.
If it stops tripping, reconnect one com-
ponent at a time until the GFCI starts
tripping. Replace the defective com-
ponent.
