If the other jets in your tub are working and only one is not, then the most common cause of this is a blockage in that particular jet or a fault on your hot tub jet settings.

When something is blocking your hot tub jet from working, NEVER poke the pipe with a screwdriver. It might be tempting and seems to be an easy solution to your current issue, but there’s a good chance you’ll create more problems when you accidentally puncture a hole in one of your hot tub’s pipes.

None of my Hot Tub Jets Are Working Fix

When all of your hot tub jets are not working, the first thing you should check is your hot tub settings. Hot tubs can be complicated for some owners, and the most common reasons why the jets won’t turn on is because they really are not turned on and it’s just a simple user error.

You may have accidentally switched the jets off or put your tub on a different mode, if that’s the case, all you have to do is change it back to its usual settings.

If you’ve just used your hot tub and did not drain the water and refilled it recently, then you might be experiencing an electrical fault in your tub. An obvious sign for hot tub electrical problems is an error code on your control panel display screen.

There’s only one way you can do if your hot tub has an electrical issue that’s causing your hot tub jets to now work at all, and that’s to turn your hot tub off and on again. If doing that several times don’t fix the issue, you might have to call a hot tub professional or service engineer to help you diagnose and fix your hot tub problem.

Another reason why the jets of your hot tub may not be working is due to an airlock in its system. This means an air pocket forms in your pump, and instead of it pushing water out, it just sits there full of air.

To fix the hot tub airlock, you need to turn on your hot tub system but turn the heat as low as possible. Ensure that all jets are open, and wait until you see the air bubble up. You might have to leave your hot tub running until the airlock is pushed out of its system.

If that option does not work, then you can either call someone to assist you with more knowledge and experience on these types of things, or you can try doing this method.

  1. Untighten the discharge pipe to bleed the air from the system. Do not remove the coupling completely.
  2. Turn on the pump while the coupling is loose, listen if a pocket of air will be pumped out.
  3. You can turn off the pump once you see the system discharge water.
  4. Tighten the coupling and get ready to use your hot tub again.

For those hot tub owners who have been using their tubs for quite a while now, you may start noticing that your jet nozzles are becoming hard to adjust due to scale buildup.
