It can be stressful to lose power as a hot tub owner. Depending on the weather and the circumstances of the power outage, there are several concerns to think about including freezing, damage, and more.

If you've discovered that your hot tub isn't working after a power outage, there are some things you can do to restore power and get it fixed. With some time and attention, you should be able to get your hot tub back up and running either with or without the help of a hot tub repair technician.

To feel prepared when your hot tub isn't working after a power outage, here are a few things you should know to look for.

Be mindful of the temperature

When you notice that your hot tub isn't working after you've lost power, it's important to keep an eye on the temperature of the water. This is especially crucial if you are having extreme weather like a cold snap because you want to prevent the water from freezing.

Check the temperature of your hot tub water several times throughout the day to make sure that it's not at risk of freezing which could cause additional damage to your hot tub and its components.

Keep the cover on

Resist the urge to peel the cover off your hot tub when it's not working. The cover will help hold heat in and maintain the water temperature even when the hot tub itself is without power.

On the off chance that you're only without power for a short period of time or need to fix something minor before the hot tub will get back up and running, keeping the cover on can save you quite a bit of headache.

If you do have to lift the cover to check the temperature or fix a certain component inside, make sure to only lift it briefly.

Have a plan for what you need to do while the cover is off, open it as little as you can to do what you ended to do, and make sure you replace it as quickly as you can to retain as much heat as possible.

Check for blown fuses or breakers

If your power comes back on after the outage and you find that your hot tub is still without power, check the breaker panel in your home and fuses on the hot tub itself before you get too worried.

Checking fuses

Anything in your home that draws significant electricity like a hot tub can sometimes blow a fuse during a power outage, but it's an easy and inexpensive thing to fix yourself.

If you think you blew a fuse, you can pick up replacement fuses at a local hardware store for just a few dollars. Fuses are very easy to replace yourself in just a few minutes if you discover that one is blown.

To check if you blew a fuse, look at the owner's manual for your hot tub and locate the fuses. If you've misplaced the owner's manual, you should be able to Google your hot tub model and find the same information.

Depending on the location of the fuse that is blown, you may need to call a repair technician to diagnose and fix the problem. Some fuses are easily replaced on your own, but the internal components sometimes require a trained eye.

Checking the breaker

Your hot tub power problem might be as simple as tripping the breaker for your hot tub. If that's the case, you'll be back up and running in no time.

Check the breaker panel in your home and see if the one labeled for your hot tub is flipped in the opposite direction of the rest of the breakers. If so, you can most likely just simply reset the breaker and that should restore power to your hot tub.

Continue to add hot water

When your hot tub is going to be without power for a long time in cold temperatures, you need to keep the water inside warm.

This is important if you know that power won't be restored for a period of time or if you need to wait for a professional hot tub technician to come and fix the problem. If the water in your hot tub gets too cold and eventually freezes, the ice could cause damage to the components of your hot tub that would be costly to fix.

In addition to just monitoring the temperatures, you want to consistently add hot water to the hot tub each day as well. While this will likely not keep the temperature at its usual, comfortable temperature, it should keep the water warm enough to stop it from freezing.

Test water levels before use

Once you've got your hot tub back up and running after the power outage, of course, you want to jump right in for a relaxing dip after all your hard work. As tempting as this may be, it's best to hold off until you can test the water.

Rapid temperature fluctuations and adding fresh water can have an impact on the chlorine and pH levels in your hot tub. Once your hot tub is fully functional again and has come back up to temperature, test the levels and treat with the appropriate chemicals before using it again.
