Hot tub jets are what make your spa relaxing and therapeutic. When they stop working properly, it can be frustrating and often signals a problem with water flow, air supply, or the pump system. Whether you live in Ottawa, Barrhaven, Orleans, or Stittsville, knowing the common causes of jet issues can help you troubleshoot before calling in a professional. Here are the main reasons your hot tub jets may not be working—and what you can do about it.
1. Clogged or Dirty Filters
If your filters are clogged with debris, water cannot circulate properly, and the jets will lose pressure.
How to fix it: Remove the filter and rinse it with a hose. For deeper cleaning, soak it in a filter cleaner solution. If the filter is old, replacing it may solve the problem immediately.
2. Airlock in the Plumbing
Air trapped in the water lines can prevent the pump from pushing water to the jets. This often happens after draining and refilling your hot tub.
How to fix it: Bleed the air from the pump by loosening the union fitting slightly until water flows steadily. Restart the pump to restore circulation.
3. Malfunctioning Pump
Your jets rely on the circulation pump to push water through. If the pump is weak, noisy, or not running at all, the jets will not work correctly.
How to fix it: Check for tripped breakers or reset the GFCI. If the pump still fails, it may need professional repair or replacement.
4. Blocked Jet Nozzles
Sometimes the issue is as simple as dirt, calcium buildup, or debris clogging the jet openings.
How to fix it: Remove the affected jet (if your model allows) and clean it thoroughly. For jets that are not removable, scrub the nozzle with a soft brush to clear the blockage.
5. Low Water Levels
If your spa water level is too low, air can get sucked into the system, causing weak or non-functional jets.
How to fix it: Refill your hot tub so the water is at least halfway up the skimmer opening. Restart the system to restore normal jet pressure.
When your hot tub jets stop working, it is usually caused by dirty filters, airlocks, blockages, or pump issues. Many of these problems can be fixed with simple maintenance, but persistent issues may require professional service.
