GFCI Protection

Your spa may be equipped with a GFCI Protection 
feature. If your spa does have this feature enabled, the 
GFCI Trip Test must occur to allow proper spa function.

Within 1 to 7 days after startup, the spa will trip 
the GFCI to test it. (The number of days is factory 
programmed.) The GFCI must be reset once it has been 
tripped. After passing the GFCI Trip Test, subsequent 
GFCI trips will indicate a ground fault or other unsafe 
condition requiring the power to the spa to be shut off.

GFCI Trip Test Procedure

The installer can cause the GFCI Trip Test to 
occur sooner by initiating it with the following 
button sequence.

Press “Temp”, then “Jets”, then “Light.” (Each press must 
be within 3 seconds of the previous press.) Press the 
“Temp” button repeatedly until “

” is displayed. Press 

“Jets” to select it. Press the “Temp” button until “

” is 

displayed. Press “Jets” to initiate the GFCI Trip Test.

The GFCI should trip within several seconds and the spa 
should shut down. If it does not, shut down the power 
and manually verify that a GFCI breaker is installed and 
that the circuit and spa are wired correctly. Verify the 
function of the GFCI with its own test button. Restore 
power to the spa and repeat the GFCI Trip Test.

Once the GFCI is tripped by the test, reset the GFCI and 
the spa will operate normally from that point. You can 
verify a successful test by navigating to the “

” item 

as described above, pressing “Jets” and then pressing the 
“Temp” button until you see “

”. The code signifies 

GFCI Status - Passed.

The system will exit this menu in 30 seconds if no 
buttons are pressed.
