Diagnostic Tools: Clamp-on Ammeter, Voltmeter
Suggested Spare Parts: Ozonator, Circuit Board, Control Panel
Standard Troubleshooting Approach
Refer to pages 43-46 for testing points.
Turn power to hot tub off and on.
Wait approximately two minutes
for lter cycle to begin and turn
on the circulation pump and
ozonator.
DO NOT press either JETS

Is 120 VAC* or 240 VAC present
at circuit board ozone outputs?
Test points 16 and 17, See pages
43-46.

models only.
Is there a faint buzzing sound
coming from the ozonator’s
internal high voltage arching
chamber? Or is there current
draw from the ozonator
(≈ 0.1 Amp)? Check with clamp-
on ammeter.
A faint buzzing sound and/or
current draw is proof that the
ozonator is working.
Read steps outlined above to
ensure customer understands
ozone logic.
