7 Reasons: Hot Tub Trips Breaker with Jets On: Solutions

Have you ever been excited to hop into your hot tub, only to find that the moment you turn on the jets, the breaker trips and everything goes dark? That’s no fun at all! This sneaky problem can catch you off guard and ruin a relaxing time.

In today’s blog post, I’ll share the exact reason why your hot tub trips the breaker when you turn on those soothing jets. I’ll explore the common causes and share some helpful tips on how to get your hot tub back in tip-top shape.

There are lots of possible causes of electrical problems tripping breakers when jets are turned on, including exposure to moisture, short circuit, ground fault, broken GFCI or outlet, loose connection, wiring, and worn breaker. But one of the most common is a GFCI-related issue. Try to diagnose your GFCI outlet properly. If you find any issues with your GFCI outlet, replace it with a new one that is compatible with your hot tub jet’s power/load.

Should I be Worried If My Hot Tub Breaker Keeps Tripping?

A hot tub breaker that keeps tripping might be annoying, but it could also be a sign of a bigger issue. Your hot tub’s breaker acts like a superhero, protecting you and your tub from harm. When it trips, it stops too much electricity from flowing.

Sometimes, it’s an easy fix. You might have too many things plugged in around your hot tub, like fancy lights or a mini-fridge. Try unplugging those to see if it helps. Other times, you could have a wet breaker box. If that’s the case, get it dry and make sure it’s sealed tight to keep water out.

But what if it’s not a simple solution? Then, it’s time to call in a hot tub professional. They’ll check your hot tub’s wiring, motor, and heater for any problems. Having a professional on your side ensures you can get back to enjoying your hot tub safely and worry-free.

7 Must-Have Causes for Hot Tub Trip Breakers When Jets are Turned On

You may find lots of problems to solve your question, but I have only shared the top causes that mostly happen with every user.

1. Exposed to moisture in Hot hot tub breaker box

Why does moisture get into the breaker box? Well, hot tubs produce a lot of steam and water splashes, especially when the jets are running. Over time, this moisture can find its way into the breaker box, even if it’s located far from the tub. And here’s the thing: Water and electricity don’t mix well. When moisture enters the breaker box, it can cause electrical shorts and other problems, which leads to the breaker tripping when you turn on the jets.

To prevent this issue, it’s essential to keep the breaker box dry and protected from moisture. You can do this by installing a weatherproof cover on the box or sealing any openings with silicone caulk. It’s also a good idea to check the box regularly for signs of moisture and clean it as needed.

2. Short circuits and ground faults

Let’s talk about short circuits. These happen when electricity takes a shortcut through a path with less resistance than the intended path.

So, why do short circuits happen when the jets are turned on? Well, if there’s a problem with the wiring, turning on the jets might push too much electricity through the wires, creating a short circuit and tripping the breaker.

Now, let’s talk about ground faults. When electricity leaks from the intended path and flows to the ground through an unintended route, you call it a ground fault. A ground fault is bad because it can cause electric shocks or even fires.

To prevent this, you can use a ground fault circuit interrupter (GFCI) that can easily shut off the electricity if a ground fault is detected.

Sometimes, water can cause a short circuit, especially when the jets are turned on. If this happens, the GFCI will sense the ground fault and trip the breaker to keep you safe.

In either case, it’s a good idea to have an electrician check things out to keep your hot tub fun and worry-free.

3. Broken GFCI Breaker or Outlet

If the GFCI breaker or outlet is broken, it cannot detect imbalances in current correctly. As a result, when you turn on the jets, the breaker might mistakenly think there’s a fault and shut off the power, causing it to trip.

So, if you’re experiencing frequent trips, hire a professional electrician to check your GFCI breaker and outlet. They can diagnose the issue and replace any faulty components to ensure the safety of your hot tub experience.

4. Loose electrical connections

Loose electrical connections cause resistance, which makes it harder for electricity to flow. Resistance leads to heat, and too much heat can damage your hot tub’s wiring. When you turn on the jets, the pump works extra hard, requiring more power. If there’s resistance from a loose connection, it can generate enough heat to trip the breaker as a safety measure.

Now, you might wonder how these connections became loose. There are a few reasons.

  • Your hot tub might have been installed a long time ago, and connections can loosen over time.
  • Vibrations from the hot tub’s pump and jets can jostle those connections, making them wiggle loose.
  • Temperature changes from hot water and cold air can cause expansion and contraction, which can also lead to loose connections.

To fix this problem, you’ll need to tighten the connections in your hot tub’s electrical system. Make sure to turn off the power before you start, and ask an adult for help if you’re unsure. Once the connections are secure, your hot tub should be ready for a bubble-filled, relaxing time without any breaker-tripping surprises!

5. Damage to the Hot Tub’s Other Faulty Components

You may face breaker-tripping issues due to faulty components like a pump or heater. If these hot tub parts are not installed properly, they can draw too much power and cause the breaker to trip.

Sometimes, the problem can be with the breaker itself. If it’s old or weak, it might not be able to handle the actual power needed to run jets. So, your hot tub breaker trips due to damaged wiring, faulty components, a weak breaker, or water issues.

6. Worn Hot Tub GFCI Breaker

Over time, the breaker can become less effective due to age and power surges. If the GFCI breaker is worn out, it may not be able to handle the sudden surge of power caused by the jets, causing it to trip even if there is no real danger or electrical fault.

To avoid this issue, I highly recommend testing your GFCI breaker periodically and replacing it if necessary. Moreover, always ensure your hot tub’s electrical components are properly maintained and in good working condition.

7. Incorrect GFCI wiring with a hot tub

If your GFCI is wired incorrectly, it may not be able to do its job properly, causing the breaker to trip when the jets are turned on.

You may face incorrect GFCI wiring due to the load wires connecting to the line terminals. This simple mix-up can interrupt your GFCI’s ability to work properly.

To fix these problems, turn off the power to your hot tub. Then, double-check your GFCI wiring, making sure the line and load wires are connected to the correct terminals. Also, inspect the ground wire to ensure it is securely fastened and connected to the right spot.


I hope this blog has been helpful in identifying the root cause of your hot tub breaker tripping when the jets are turned on. Remember, you should always prioritize safety and get a professional electrician to handle any electrical issues.
