[2024 Solutions][Bathtub] Hot Tub Jets Won’t Turn Off?

Airlocks and blockages are the most common causes of jets not working. Luckily, these are both easy fixes. Airlocks most often occur when a hot tub has recently been refilled. In this case, jets should be turned on and off a few times in a row in order to push out any air that may be trapped within them.

Alternatively, the top fitting of the pump may be loosened but only until air is heard escaping and a small amount of water escapes the pump. Then, it should be tightened once again. Or, if the jets are simply blocked, they should all first be turned to ensure they are open.

Then, users should check the jets for calcium buildup or other debris that may have accumulated. Finally, the hot tub should be sufficiently filled with water, and the filter should be cleaned. If these methods don’t work, there may be a more serious issue present, and the help of a professional might be required. 


Have you gotten your hot tub accessories this year?

Honestly, when I experienced a hot tub for the first time, it was good enough for me. It hasn’t gone a lot before I thought how cool it would be to have a drink in my hot tub, watch a game or bring my food with me. I had no idea people already made things for your hot tub so you can do just that. I have a long list of hot tub accessories that might be interesting to you. Click here to read the article.

How do you Turn Off Hot Tub Jets?

In most hot tubs, the jets are set to automatically turn off after specific time periods. For example, high speed jets typically turn off after 15 minutes of use, and low speed jets turn off after 2 hours.

However, if users wish to manually turn off a hot tub’s jets, they can do so.

Usually, there is a designated jets button on the hot tub. This button should be pressed until the jets begin to turn off. It usually takes 3 pushes to achieve this goal. This does not turn off the entire hot tub and is not commonly needed as hot tubs tend to regulate themselves decently well. 

What Causes Hot Tub Jets to not Work?

The most common causes of hot tub jets not functioning properly include the jets being blocked or the pump not working correctly. If the jets stop working, users should open them and ensure there are no blockages or calcium buildup, and the hot tub’s filters should be thoroughly cleaned.

If after these steps, the jets still are not working, the hot tub’s pump should be checked. In order to do this, the access panel and airlock valve close to the pump should be opened. This allows for a release of air that creates a greater flow of water to the air. 

In case you want to be sure that there is nothing in your system blocking the flow, make sure to pick some some chemicals that can help you with that. Here is my suggestion.

Why does my Hot Tub Keep Shutting Off?

If a hot tub is continuously shutting off, it is likely it is tripping the breaker. There are 7 common causes that cause this to happen including a worn GFCI Breaker, moisture in the breaker box, corrosion, loose or damaged wires, faulting components, a bad heating element, or a flooded air blower or ozonator.

If any one of these instances takes place, the breaker will trip alerting owners to the issue. Rather than just flipping a breaker switch, the problem area should be identified and resolved in order to stop the hot tub from continuously shutting off and prevent any irreversible damage that may otherwise occur. 

How do you Reset a Jacuzzi Tub?

In order to reset a Jacuzzi tub, all of the water must first be drained. Users should do this by using the main control panel, and the valves below the control panel should be turned.

This step can take up to an hour as the water drains slowly. Then, the Jacuzzi tub should be turned off entirely, and if possible, it should be unplugged from any power outlets.

Next, the tub should be thoroughly cleaned, and the jets and filters should be given extra attention as they are common culprits of hot tub malfunctions. Finally, the Jacuzzi tub can be reset using a button typically found located on the tub’s heater unit. 

What will you do if you notice Yellow Gunk in your hot tub?

This is certainly not a pleasant view, however, it’s fixable. Don’t let it surprise you and ruin your hot tub time. Read this article to prepare yourself.

Do you Leave Jets on in Hot Tub?

Hot tub jets can be left on, but they do not have to be on at all times. Ultimately, the decision to turn jets on and off depends on the preferences of the hot tub’s users.

However, when left untouched jets regulate themselves and turn on and off automatically in order to maintain the hot tub’s internal heat. Therefore, if the temperature dips below the set point, the jets will turn on until the temperature has been raised sufficiently.

However, if users wish to preserve energy, reduce a hot tub’s temperature, or simply do not want to be bothered by jets or their noise, they can opt to manually turn them off using their power button with no harm done to the hot tub.

It is important to note that a hot tub’s jets should regularly run in order to prevent water from becoming stagnant which may harbor bacteria making the hot tub unfit for use. 

Can Bromine or Chlorine Affect my Hot Tub Jet?

One important thing to remember about hot tub jets is that they are purely mechanical devices, and not very complex either.  99% of the jets used in hot tubs are plug-in nozzles that churn up the high-pressure water flowing through them, creating a pleasing massage for the user.

Your jets do not live in isolation, however.  As they soak in your hot tub, day after day, whatever goes into the water affects them.  Algae, shampoo, hair conditioner, makeup and sanitizing chemicals all collect on the hot tub jet bodies. 

It turns out that the same chemicals (bromine and chlorine included) that keep your hot tub clean are also responsible for the wearing out of your jets.

The biggest cause of premature jet failure is chlorine.  In addition to killing microbes and dissolving organic material,  chlorine causes the plastic in the jet bodies to become brittle.  Brittle plastic breaks, which is why the jets pop out of the tub wall.

If you would look at the old hot tub jet and a new one, you would notice that the mounting tabs on the old jet are worn down due to its usage.  Those two little tabs are what hold the jet into the wall.  It doesn’t take a lot of damage to wear the tab out to the size that it won’t hold the jet in place.

Most hot tub jets will eventually wear out, and it wouldn’t be unusual to replace all the jets at least once over the 20-year lifespan of a well-cared-for hot tub.  But too much chlorine or bromine will wear your jets out faster.  

How do I Make my Spa Jets Stronger?

If there is not enough water pressure to provide powerful enough water flow to a hot tub’s jets, it will likely feel as if the jets are not working properly.

However, there are a few easy fixes to create a stronger stream from a hot tub’s jets. First, the hot tub’s waterfall valve should be closed. This is done simply by turning the waterfall valve off and will increase the water flow coming from the jets.

Next, the hot tub’s air jets should be opened. This extra force of air will add momentum to the water flowing from jets.

Finally, in order to create a greater concentration of water in a specific jet or jets, users can manually close the faces of the jets not in use. This will cause all the water to flow from the open jets and will create a much stronger stream. 

How do the Jets Work in a Hot Tub?

Air in, water in, and an air mixture outlet are the three components with which hot tub jets function. In order to provide water to and push it through a hot tub’s jets, pressure from the hot tub pump is used to push water through the back of the jet until it comes out the front.

While this is happening, air gets mixed into the hot tub’s pressurized water stream through a hole in the jet known as a venturi. Essentially, an intense stream of liquid, in this case water, is created by the use of pressure to force it through a smaller opening than that from which it flows from. 

How many Jets Should a Hot Tub Have?

The appropriate number of jets required for a hot tub is extremely variable. Finding the perfect number depends on the user’s preferences, how big the hot tub is, and how many people will be using it at one time.

However, it is important to remember that more is not always better when it comes to the number of jets used in a hot tub. On average, hot tubs will range in jet quantities containing anywhere from 10 to 20,  but these are not set numbers.

Furthermore, if users want to target specific areas for massage, a minimal amount of jets should be utilized in order to provide strong water flows to the jets being used. In this case 2 or 3 jets are more than enough.

However, if a hot tub is being used to entertain groups of people, 20 jets may be preferable. This number will allow for decent water pressure while also providing enough jet locations for everyone in the hot tub. 

How to Turn Off the Hot ub?

There are a few steps you can follow to turn off your hot tub:

  1. Turn off the power to the hot tub: Locate the circuit breaker or fuse box that powers the hot tub, and turn it off. If your hot tub is hardwired, you will need to flip the appropriate switch in the fuse box. If your hot tub is plugged into an outlet, you will need to unplug it.
  2. Drain the hot tub: If you want to completely drain the hot tub, you can attach a hose to the drain valve and let the water drain out.
  3. Close the valves: Close any valves that allow water to flow into the hot tub, such as the main shut-off valve and the valve that controls the water flow from the pump.
  4. Turn off the pump: Locate the switch or circuit breaker that powers the hot tub pump, and turn it off.
  5. Cover the hot tub: Place the hot tub cover over the top of the hot tub to keep debris and animals out.

Keep in mind that the specific steps for turning off your hot tub may vary depending on the make and model of your hot tub. If you are unsure of how to turn off your hot tub, it’s a good idea to consult the owner’s manual or contact the manufacturer for further assistance.
