Ozone Not WorkingUpdated 6 days ago
If your ozone system does not seem to be running or you do not see bubbles or smell ozone during operation, there may be a simple issue affecting the system. Ozone helps support clean water, so it is important to make sure it is working correctly. This guide will help you check the most common causes and restore proper ozone function.
1. Make Sure the Ozone Feature Is Turned On
Some units require activating the ozone feature separately.
Check that
- the ozone button or mode is switched on
- the controller is responding
- the system is not paused or in standby mode
If you are unsure, turn the ozone feature off and back on again.
2. Check for Bubbles During Ozone Operation
When ozone is working, you may see small bubbles entering the water or rising through the tub.
If you do not see bubbles
- check water flow
- make sure hoses are connected correctly
- confirm the pump is circulating water
Ozone relies on water flow to mix properly.
3. Confirm Water Flow Is Strong
Ozone will not work if there is low water flow.
Weak flow prevents ozone from circulating and may stop the system automatically.
Make sure
- the filter is clean
- the filter is not clogged
- hoses are not kinked
- water flow feels steady
A weak filter or blocked hose is the most common cause of ozone issues.
4. Check Hose Placement
If hoses are reversed or installed incorrectly, ozone may not enter the tub.
Inspect
- hose direction
- markings on the intake and outlet
- that both hoses are fully connected
Incorrect hose placement can prevent ozone from mixing into the water.
5. Clean or Replace the Filter
A dirty filter reduces circulation and affects ozone performance.
Replace or rinse the filter if
- the water is cloudy
- flow seems weak
- the filter is dark or worn
- ozone cycles stop early
A clean filter helps the ozone mix properly.
6. Listen for the Ozone Generator
Some ozone systems make a faint sound during operation.
If there is no sound
- turn ozone off
- wait a few seconds
- turn it back on
- listen closely near the chiller
If you still cannot detect any activity, continue with the next steps.
7. Check the Water for Odors
When ozone is working, it helps neutralize odors.
If your water develops a strong smell, the ozone cycle may not be running often enough or the system may not be producing ozone.
Increase ozone usage if the tub
- is outdoors
- is used frequently
- has multiple users
- warms up during the day
If odor continues, the ozone system may require inspection.
8. Make Sure the Chiller Is Not Overheating
If the chiller overheats, some models disable ozone until the system cools down.
Check for
- blocked vents
- poor airflow
- warm room temperatures
- dust on the vent screens
Improving ventilation may restore ozone function.
9. Restart the Chiller
A simple restart can often fix small ozone glitches.
To restart
- Turn off the chiller
- Unplug the chiller
- Wait one to two minutes
- Plug it back in
- Turn it on and activate ozone again
This resets the control panel and ozone function.
10. Ozone May Not Be Visible in All Conditions
You may not always see or smell ozone strongly, especially
- in outdoor environments
- when the tub is very cold
- if water is very clean
For confirmation, watch flow and bubbles near the return line rather than relying on smell alone.
When to Contact Support
Contact our team if
- the ozone feature does not activate at all
- you see no bubbles during ozone cycles
- the water develops odors quickly
- the ozone system worked before but stopped suddenly
- the chiller shows an ozone related error (if applicable)
