I. Trips GFCI
First, check the equipment and electrical connections for any water. Water
dripping onto equipment will cause the gfci to trip.
1.
Most common cause is the heater. If the gfci pops instantly its almost always
the heater. To isolate, do the following:
Turn off power. Remove the cover on the control box. You will see either 2 straps
running from the heater posts to the board or 2 wires that do so. If you have 2
copper straps, you need to remove both. Remove the 2 nuts or screws holding
the copper straps to the board or terminal block. Remove the 2 straps from the
heater posts. The heater posts will have a nut on the top holding the copper/wire
to the posts. Underneath the copper/wire is another nut built into the heater posts.
This allows you to place an open end wrench on both top and below to loosen
and remove the nut. Do so. You will then have a totally disconnected heater from
the loop.
Turn ON power. If the spa comes on and operates fine without tripping the gfci as
it did previously, you have identified the heater as the cause. That is common
because the heater’s element can crack or corrode enough for the voltage to leak
and the gfci to see the leak to ground and trip.
NOTE: On spas operated on 110-130vac cord, the heater will cause the gfci to
pop after the low speed pump comes and then the heater is turned on causing
the gfci to trip.
2.
If the spa still trips the spa, try disconnecting the ozonator and leaving
disconnected to test to see if that is the problem.
3.
It the two steps above don’t isolate the problem, then the low pump could
cause the problem. Usually the motor will be hot to the touch. But either way,
sporadic gfci failure is most likely the pump/motor.
4.
In rare cases the gfci tripping is caused by the board. It’s the least likely failure.
