Ozone Troubleshooting Section
Is the spa’s filtration cycle on?
The ozone system is tied to the filtration cycle. If the spa isn’t filtering, the ozone
system will not be on.
Check to see if the spa is filtering. If it isn’t or you are not sure, shut the power
off to the spa.
After 10 seconds, power the spa back up.
The spa’s control will go through a system check then turn the filter pump on.
(depending on the model, this can happen quickly or take up to 5 minutes.)
When the spa controls call for ozone, the indicator light on the topside panel (if
equipped) will illuminate, indicating that power is going to the ozone machine.

Is the topside control ozone indicator light on?
The topside control on most models will indicate that power is being sent to the
ozone machine with an illuminated LED.
To check the ozone indicator, shut the power off to the spa.
After 10 seconds, power the spa back up.
The spa’s control will go through a system check then turn the filter pump • on.
(depending on the model, this can happen quickly or take up to 5 minutes.)
When the spa controls call for ozone, the indicator light on the topside panel (if
equipped) will illuminate indicating that power is going to the ozone machine.
This indicator light does not tell you that the ozone machine is good or bad, only
that power is going to the machine.

What if the topside control doesn’t have an ozone indicator light?
Most topside controls have some sort of indicator. However on some models the
topside doesn’t have this capability.
If there is no indicator light, look at the ozone machine and there will be a purple
/ blue glow at the cell.
This tells you that the ozone machine is receiving power and generating ozone.

How often should I change the ozone cell cartridge?
The ozone cell cartridge should be replaced yearly.

Is the ozonator light supposed to glow at all times?
No, only when the filtration cycle is on
