How to Fix a Tripped Hot Tub GFCI Circuit Breaker

Finally, you're the owner of the hot tub you've always wanted. Ever since you first brought it home, it's provided you with nothing but peace, relaxation, and comfort. Except for one small thing: The GFCI circuit breaker keeps tripping, shutting off the power to your spa just when you're settling in for a soak.

GFCI issues are a relatively common occurrence with hot tubs, and often can be resolved with little fuss or expense. However, because electricity and water are an extremely dangerous combination, make sure you know what you're doing before troubleshooting any electrical problems. Unless you're confident in your ability to address GFCI issues yourself, always consult a professional hot tub repair expert or electrician. An improperly-wired hot tub can result in electrocution or an electrical fire. Electrical work such as installing a hot tub or making adjustments to its components or wiring must be performed by a licensed electrician and must adhere to all local and national electrical codes. As a reminder, always turn off your hot tub and disconnect it from the power supply before attempting any repairs.

What is a GFCI circuit breaker?

A GFCI—a Ground Fault Circuit Interrupter—is a device used to protect your hot tub from unusual fluctuations or deviations in your power supply. Ground faults and short circuits occur when electricity takes a path the designers of the circuit didn't intend. When a GFCI detects an anomaly in the electrical supply, such as a ground fault or a short circuit, it interrupts the circuit and cuts off all electricity to your spa. When this interruption occurs, it's often referred to as “tripping” the GFCI.

WHERE IS MY GFCI?

Even if you've never experienced any electrical problems with your hot tub, make sure you know where your GFCI is located. While some hot tubs are designed to plug into a traditional 120-volt outlet, most will require the installation of both a GFCI circuit breaker and a dedicated electrical outlet designed to handle the increased voltage—generally 220 to 240 volts—necessary to power your spa. Most likely, you'll find your GFCI in the control panel located close to or containing the outlet your spa or hot tub uses. To reduce the risk of the electrical supply coming in contact with water, the National Electrical Code requires that the electrical components, including the GFCI, be located a minimum of six feet away from your hot tub.

HOW DO I RESET MY GFCI?

Your GFCI should have a visible reset button. These buttons are usually red and are clearly labeled “reset.” To reset your GFCI, simply press the button. This will restore the electricity supply to your spa.

WHY DOES MY GFCI KEEP TRIPPING WHEN I TURN ON MY HOT TUB?

When your GFCI trips, it's an indication that something unexpected has happened with your electrical supply. This might be a one-time occurrence, which may be resolved by simply pressing the button to reset the breaker. If your GFCI repeatedly trips whenever you turn on your hot tub, it means there's an ongoing problem that must be addressed and resolved. There are a few reasons why your GFCI might trip each time you power up your hot tub:

  • There may be an issue with your GFCI. Disconnect all hot tub components from your GFCI, then reset it. If it immediately trips even though nothing is attached to it, your GFCI is most likely faulty and will need to be replaced.
  • There may be an issue with one of your hot tub's components, such as the heater, the pumps, or the entertainment system. If these components can be individually disconnected from your GFCI, disconnect them all, then reconnect and test them one at a time. If any of them cause your GFCI to trip when you turn your hot tub on, the faulty component will most likely need to be serviced or replaced.
  • Your GFCI may be wired incorrectly. To isolate a faulty switch or wire, disconnect wires one at a time to each switch, then test the GFCI to see if any individual wire causes it to trip.

Once again, it's important to stress that electricity can be harmful or fatal. If you aren't confident in your ability to safely troubleshoot electrical problems, call in a knowledgeable and experienced professional.

WHY DOES MY GFCI TRIP AT RANDOM TIMES?

Your GFCI may trip at seemingly random intervals, either while you're in the middle of a soak or when your hot tub is not in use. If your GFCI constantly trips, one of the following issues might be the culprit:

  • Your hot tub heater may be corroded or otherwise damaged. Problems with the heating elements are among the most common causes of GFCI issues. Inspect your heater for visible signs of damage, and try operating your hot tub with the heater disconnected to see if the GFCI problem reoccurs.
  • Your spa's electrical contacts have become corroded. Inspect each contact and replace any that show signs of corrosion.
  • One or more electrical connections is loose. With the power to your spa disconnected, tug gently on each connection, then tighten and secure any that seem to be loose.
  • The control box containing your GFCI has been exposed to moisture, such as rainwater or condensation. If the inside of your control box is damp, locate the source of the moisture, protect your box from future water exposure, and allow it to thoroughly dry out before testing the GFCI. If water has damaged any electrical components, replace them.
  • There's a short in one or more of your electric components. Run your spa for 15 minutes, then turn it off, unplug your tub, and inspect your components by hand. Electrical components that are shorting out will feel warm to the touch. Replace any components which grew warm during your test.

WHERE CAN I FIND REPLACEMENT COMPONENTS OR GFCIS?

Your local hardware store will likely have replacement GFCIs and components for sale, or you can order them online. If you're not certain which model or configuration to purchase, talk to a repair professional or licensed electrician. The best way to find components for your hot tub is often by visiting the dealer who sold it to you . They will have advanced knowledge of your specific model and will either have parts in stock, or will be able to order them for you. They'll also have experience diagnosing and repairing similar problems and may be able to offer repair services or advice.

A GFCI circuit breaker that trips constantly is at best a nuisance, and could be an indication of a potentially hazardous situation with your hot tub. Armed with a little knowledge, you should be able to diagnose the problem with your GFCI and find a way to fix it, either by repairing it yourself or by calling upon the knowledge and services of your hot tub dealer or a licensed electrician. A tripped GFCI can be frustrating, but it doesn't have to get in the way of your enjoyment of your hot tub.

Identifying and Fixing Common Hot Tub Problems

Hot tubs are a great way to relax and enjoy quality time with family and friends. But unfortunately, they can also become quite high maintenance as they require regular servicing in order for them to function properly. All hot tubs will at some stage experience faults or breakdowns due to age, wear and tear, or incorrect use but luckily most of the issues can be fixed relatively easily if you know what you are looking for. In this blog post we’ll look at the common problems associated with hot tubs and how best to address them. With the help of this guide, you should be able to identify any issue that may arise with your hot tub quickly so that it can be resolved efficiently!

Knowing When to Replace Your Hot Tub Filter

Hot tub filters are essential for keeping your hot tub clean and running smoothly. Over time, they can become clogged with debris, making it harder for water to circulate through the tub. This not only affects the quality of your hot tub experience, but it can also cause damage to your hot tub’s pump and other components. So, how do you know when it’s time to replace your hot tub filter? Look for signs like cloudy or murky water, strong chemical odors, or reduced water flow. Checking and replacing your hot tub filter regularly can ensure that you continue to enjoy a relaxing and rejuvenating soak every time you use your hot tub.

Identifying Common Water Leaks in Hot Tubs

Hot tubs are a wonderful way to unwind and relax after a long day. However, a common issue that hot tub owners face is water leaks. Identifying these leaks early is essential to preventing bigger, more costly problems down the line. There are a few common areas where leaks tend to occur, such as at the heater union, pump union, and filter housing. Another potential area for leaks is the diverter valve, which controls the direction of the flow of water through the jets. It’s important to regularly check these areas for signs of leakage, such as puddles or drops of water around the base of the hot tub. By staying vigilant and addressing leaks as soon as they’re spotted, hot tub owners can ensure that their oasis remains a place of relaxation and not a source of stress.

How to Fix a Hot Tub That Won’t Heat Up

Picture yourself on a cold winter night, ready to jump into your hot tub after a long day. But as you step in, you realize the water is ice cold. Nothing is more disappointing than a hot tub that won’t heat up. Luckily, there are some simple steps you can take to fix the problem and make sure your hot tub is ready to use anytime you want to unwind. One of the first things you can do is to check the spa’s heater. If it’s not running, it may need some troubleshooting or repairs. Another common issue is a filter that needs cleaning. A dirty or clogged filter can prevent the water from circulating properly, which can lead to a chilly hot tub. With some careful attention and a little know-how, you’ll be soaking stress-free in no time.

Tips for Troubleshooting Electrical Issues with Hot Tubs

Hot tubs provide a relaxing and therapeutic experience, but when electrical issues arise, they can quickly turn into a headache. Fortunately, there are steps you can take to troubleshoot common electrical problems with your hot tub. The first thing to check is the power source. Make sure it’s plugged in and the circuit breaker isn’t tripped. If everything looks good with the power source, move on to check the control panel for any error messages or flashing lights. It’s also important to inspect the wiring and connections to ensure they are secure and free of damage. Don’t let electrical issues ruin your soak in the hot tub; if you are wary of messing with the electrical system of your Sonoma hot tub, we are here to help.

How to Clear Clogged Jets on a Hot Tub

Relaxing in a bubbly hot tub is one of life’s little luxuries. But when those jets get clogged, it can feel like a major inconvenience. Fear not, clearing clogged jets on your hot tub is a straightforward process that you can do yourself. The first step is to turn off the power to your hot tub and remove the filter. Next, use a screwdriver to remove the cover of the jet that needs to be cleared. From there, you can use a pipe cleaner, toothpick, or other small, soft object to clear out any debris. Once finished, reattach the cover and filter, and you’ll be back to enjoying your relaxing soak in no time.

Strategies for Dealing with Low-Pressure Problems on Hot Tubs

Unwinding in a hot tub is one of the best ways to relax after a long day. But what happens when your hot tub’s pressure drops? This low-pressure problem can be frustrating, but don’t worry – there are some strategies to help you deal with it. First, check if the water level is too low. Refill if necessary. Make sure the jets and filters are clean and free from any debris. If you still have low pressure, it may be time to replace your hot tub’s pump or motor. It’s important to address low-pressure problems promptly to avoid further damage to your hot tub. After all, you deserve to relax in the perfect spa experience.

In conclusion, maintaining a hot tub involves many considerations from recognizing when it’s time to replace your filter to spotting common water leaks. Knowing how to repair routine issues like electrical faults and low-pressure problems will save you time and money in the long run. If correctly maintained , you can ensure a steady stream of therapeutic bubbling for as long as you own the hot tub. Whilst gaining knowledge is important there is no substitute for regular preventative and professional maintenance that ensures your hot tub stays in optimum condition carrying out it’s magical relaxation functions for many years to come!

Tripped GFCI/RCD Breakers

The ground fault circuit interrupter (GFCI) or residual current device (RCD) protects your spa from the event of any electrical fault that could cause electrocution. The device shuts off when it detects electrical current flowing along an unsafe path. Often these devices are set to be incredibly sensitive to even the lowest of electrical currents for safety reasons. Unfortunately this can also result in the breaker tripping for even the smallest of issues, such as water in the ozonator . 

Heater Failure

If your spa is having issues getting warm, it could be a heater failure! Most failures are due to heating element corrosion. This can be caused by low ph in the water supply. Low PH (below 7.0) for an extended amount of time will cause damage to the heating element and trip the GFCI breaker. Most issues can be avoided with proper water chemistry maintenance. Troubleshooting for heater failure includes checking the filter and thermostat for damage.

Leaky Seals

If you are having water chemistry issues checking for leaky seals can save time and money. Replacing old o-rings, pump seals and ensuring that the filter is clean is the best way to avoid leaky sealing. Unchecked, you may find that water leakage and buildup is occurring around the spa equipment that can cause an electrical short. For more details and information on fixing a leaky hot tub, check out our leaky hot tub troubleshooting guide.

Malfunctioning Pump

Humming or hammering noises coming out of the hot tub are a good indicator of a malfunctioning pump. Worn out bearings, broken seals, or leaky water are all signs of caution. This is not the type of hot tub problems that you want. It is a good idea to try and stay ahead of these issues with monthly or yearly maintenance to these areas. For more information on troubleshooting your pump without breaking the bank, our pump replacement guide has you covered.

Hot Tub Line Leaks and Weak Jets

As mentioned previously, hot tubs are very sensitive to poor water chemistry. If the PH balance is not corrected it is likely that silicone corrosion will occur, causing weak jets and line leaks. The best way to avoid this is to winterize your spa correctly , cleaning each jet line and fully draining the hot tub before closing it for the season.

Poor Water Circulation

Poor water circulation can be caused by not running the pumps long enough. For optimum flow, you should run your pumps for one hour for every 10 degrees of temperature. Water chemistry problems (PH imbalance) causes corrosion on the pump seals and negatively affects circulation. The better that the water is circulating the cleaner the spa, so make sure to check filters and wipe the spa walls for grime to prevent biofilms from growing and clogging the lines.

Circuit Board Malfunction

A burnt-out circuit board can be a costly repair, and is the ultimate consequence of poor hot tub maintenance. Routine maintenance is the best way to avoid expensive issues such as circuit board malfunction. Loose heater terminal connection screws can vibrate over time and loosen the connection with the heater, resulting in damage to the circuit board. The board builds up heat and is overloaded, causing in irreparable damage and an expensive replacement. Components failure is marked by burn marks, cracks or melting. Most systems will generate an error code if the circuit board is having issues.

Future-Proof Your Spa

If there is one common denominator for all of these long term hot tub problems, it is that proper water maintenance is key if you want to save on costly repairs. The fact is, most if not all of these common problems can be avoided! If your hot tub is accessible to outdoor critters or rodents, make sure you check for frogs, bees, or mice who may want to take a plunge into your spa. Frogs are attracted to the heat of your spa and can get in if the spa is improperly covered. Sensitive wiring can be chewed out by mice if they decide to move in, start a family and call your hot tub their home. By maintaining a healthy PH balance and performing routine maintenance on your spa you can save money and time on repairs.

Routine Check-Ups!

Routine check-ups for breaches in the hot tub shells or nearby nests will ensure no long-term damage is done by the intruders. The best way to keep pests out is to maintain healthy water chemistry and keep your cover sealed tight!

Hot Tub Troubleshooting

Hot tub Setup

There are two basic types of hot tub electrical setups. One is the plug and play model that simply plugs into a standard electrical outlet. This type of spa has a 110v heater in the U.S. and Canada and usually comes with a GFCI mounted directly to the power cord.

The other more robust type of installation is a 220-240 volt installation that requires an electrician to run the proper gauge wire from the circuit breaker panel through the GFCI or outside disconnect and then to the spa control box.

Installation and Wiring diagrams usually come with the spa or are found in the instruction manual.

Note that the white or neutral wire can sometimes trip up even seasoned electricians when it comes to hooking up a hot tub GFCI.

Most 220 volt hot tub systems require 4 wires in North America. The two hot legs are black and red which provide 120v+120v or 240v potential difference between them. The green is always ground and the white is the neutral wire. 120 volt spa components derive their voltage between a hot leg and the neutral wire, whereas the 220 volt heater gets the voltage between the two hot wires. Note that 4 wire service must not be connected to standard 3 wire services. A disconnect subpanel near the spa (depending on code requirements) has a GFCI and manual shutoff.

Outdoor wiring is usually concealed inside conduit made of PVC plastic, or flexible conduit. Do not use aluminum wiring, but use copper wire instead for all hot tub wiring.

Hot Tub Electrical Problems

Caveat: Never attempt to do electrical repairs on any appliance or device that you are not qualified to do as the mix of water and electricity can be extremely dangerous.

There are many symptoms that can cause a problem with spas. From a general wiring and circuit breaker issue that can render the entire spa useless, to a particular component within the spa that may be causing a short circuit or other electrical issue. Hot tub components that can cause issues include:

  • Circuit Breaker
  • Spa Topside Control
  • Hot Tub Circuit Board and Relays
  • Circulation Pumps

Circuit Breaker Tripping?

This is a problem that requires troubleshooting skills to isolate the problem component. Culprits could be any one of the many components attached to the spa such as an air blower that has water buildup inside of it causing a short circuit etc..

When a spa does not work at all, technicians check the main spa leads for power to determine whether the problem is within the spa or outside of the spa in the main wiring or panel.

Many times if the problem is within the spa, technicians will unplug the individual components and plug them in one by one until the fault occurs. If the spa pack works with no components attached to it, then the problem may be with one of the pumps, blowers, ozonators or other devices plugged into the spa pack or circuit board.

Once a component has been found to have a problem, the part can easily be replaced by ordering a similar replacement part online, many times with free delivery. The part is then swapped out and the spa is up and running again.

Typical components that are exchanged in spas include the heater, pumps, blower and even circuit board or entire spa pack.

Most often, circuit boards are not repaired, but just replaced, although there are repair kits available for pumps and sometimes only the wet end of a pump is needed, so it is cheaper to buy just that part rather than the entire pump. If the pump is older than about 5 years, then it makes sense to just change out the entire pump if that was the component that caused the problem as pump seals can begin to wear over time, especially when subject to imbalanced water over extended periods of time.

Hot Tub Or Spa Control Panel Not Working? (How To Fix It)

Published: May 4, 2021

Rick Patterson

Modern hot tubs come equipped with automated control systems to allow you more time relaxing, and less time fiddling around getting it to work.

But as we all know, technology can be a finicky thing, and sometimes the hot tub control panel might not work properly.

We’ll go over potential issues that can arise and how you can troubleshoot them for a quick fix.

Know Your Hot Tub Control Panel

The hot tub control panel is a functional display system that operates all your tub’s features. It handles everything from the main power, to the spa jets , and even things like the lights and music.

A standalone hot tub has the control panel built into the top of the tub. This is known as a topside control panel.

It consists of a small screen outfitted with LEDs or LCDs, with various buttons and indicators covered in an overlay. The buttons control the functions and the screen communicates to the user what current function is being carried out.

Both digital and analog panels exist, and they’re designed to work only with specific control boards.

If you have a tub that was built from the ground up, the controls will be housed with the rest of the spa equipment. This is known as a spa side control panel. 

Many spa side controls will be linked up with a remote, so you can still access the control system while in the tub. In most cases, the remote will be installed at the tub, and hardwired back to the control panel through tubing.

With recent advances in technology, wireless remotes are also available, although they are usually only compatible with certain controllers. 

How To Fix A Hot Tub Control Panel (Troubleshooting)

Issues with topside and spa side control panels are varied, so we’ve compiled a list of the most common problems and what you can do to rectify the issues.

If The Display Won’t Turn On

If the display isn’t showing anything, you’ve got a problem.

Follow these steps to get it operational again”

  • Start by resetting the spa controller. Sometimes this universal “trick” can fix any electronics issue. Turn off the power, wait for 20 seconds, and turn it back on. 
  • Check the controller for any condensation that may be present between the overlay and the display.
  • Inspect the cables that run to the controller. They may have come loose, or been damaged in some way (rodents like to gnaw wires). Ensure all cables are connected cleanly as well. You may have a situation where the termination point has failed for one reason or another and needs a new end on it.
  • Check the circuit board transformer to make sure there is power.
  • Ensure power is present at the fuse and that it isn’t blown.
  • Double check that the topside controller is compatible with the circuit board model.
  • Look over the circuit board for any damage on it. Any compromised areas could cause the display to fail.
  • If none of these work, you may have to fully replace the topside controller, as they do have a shelf life of around 10 years.

If The Display Shows An Error

If the display shows an error message, you should consult the hot tub’s owner’s manual to cross reference the message you’re seeing.

A display error that’s blinking or flashing may only need something as simple as a system reset, whereas any kind of truncated display can indicate there is moisture or dirty contacts inside the controller.

Most error messages can be fixed, but you might need to get a new one depending on the age of the controller.

If The Display Is Wrong

Sometimes, a display will begin showing the wrong information.

This borders on error messages (see above), however, it also may be presenting the right information, but with compromised LEDs that make it look incorrect.

An issue like this could be the result of a cracked panel, or one that has been exposed to moisture. In this case, a full panel replacement is usually the best solution.

A wrong display can also be a sign that the control panel has run its course, and again, will require replacement.

If The Display Flickers On And Off

A flickering display is a sign that the voltage from the transformer is too low.

You can test it using a multimeter, but if voltage isn’t your specialty you may want to call a professional to fix it.

Additionally, you may have an issue with the cable from the control panel being too close to another cable in the filtration system .

These lines can “cross” if they’re too close to each other, causing the display to act erratically.

If The Spaside Buttons Won’t Work

Unresponsive buttons are an issue you may encounter with your controls.

This could be the result of a damaged panel, insufficient voltage, or a faulty connection between the control panel and the circuit board.

To fix it, try the following:

  • Start by verifying the DIP switches on the board are in the factory default positions. If they need to be repositioned, turn off the power to the tub before resetting them.
  • Inspect the connection between the board and the control panel. The connection could be compromised in some way (loose, bent, damaged) and needs to be fixed/replaced.
  • Ensure the voltages between the control panel and the system pack terminal block are compatible.
  • Enter “Priming Mode” on your control panel and test the buttons.

Don’t Lose Control!

No one likes a hot tub control panel that’s not working properly.

Not only is it inconvenient and a nuisance to troubleshoot, repairing it can be an unexpected expense and replacing it can be even more costly .

The silver lining is there are remedies for a malfunctioning control panel, you just have to decide if you want to fix it yourself or hire a professional to do the job.
