8.13 Ozone not working
Diagnostic Tools: Clamp-on ammeter and voltmeter.
Suggested Spare Parts (Page 59): Ozonator, circuit board, control panel.
Standard Troubleshooting Approach
Danger: Electrical Shock Hazard Exists!
High Voltage Present On Circuit Board. Use Extreme
Caution While Servicing Circuit Board.
Turn power to hot tub off and on.
Wait approximately two min-
utes for filter cycle to begin and
turn on ozonator and circulation
pump.
DO NOT press either JETS button
at this time or ozonator will shut
off!
Is 120 VAC* or 240 VAC present
at circuit board ozone outputs?
*Convertible models only.
Is there a faint buzzing sound
coming from the CD 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 CD
ozonator is working.
Read steps outlined above to en-
sure customer understands ozone
logic.
*Replace ozonator.
Replace control panel.
Replace circuit board.
Turn power off, plug in
spare control panel, then
turn power on. Wait ap-
proximately 2 minutes for
filter cycle to begin. Is filter
cycle running?
*Note: Check the fuse inside the
ozonator before replacing the unit.
