Water entered through the round seal
The round seal of Fitbit sense is not prefect for all types of water activity. So if you use the smartwatch in a way that is not suitable with the smartwatch, water can enter though the round seal and your water face issues after swimming. Entering water issue is the most common reason for this. You have to take special care while wearing Fitbit sense during any kind of water activity because a single mistake can cause damage to your smartwatch.
Empty battery
If you’re an avid swimmer, you may have noticed that your smartwatch doesn’t seem to last as long as it does when you’re not swimming. This is because swimming is a very strenuous activity and puts a lot of strain on your smartwatch’s battery. While it’s rare for your smartwatch to completely die while you’re swimming, it is possible for the battery to become drained more quickly than usual. To avoid this, make sure to keep an eye on your smartwatch’s battery level and charge it up before you go for a swim. With a little bit of planning, you can ensure that your smartwatch will be there to track your swims – even if your battery isn’t at 100%.
Incorrect watch settings
If your watch’s settings are incorrect, you may also face issues after swimming. It is not the turn-on issue, and it is a tracking issue. As you are already using a Fitbit Since you already know that you can enable swimming mode before you start swimming. If the settings remain the same after swimming, you may face some tracking issues after swimming.

How to Fix Fitbit Sense not Working After Swimming

I understand how frustrating it is when you see your favorite smartwatch won’t start after your finish your swimming. Though there is no guaranteed fix for this issue, you can try fixing it. If you are lucky enough, your smartwatch will get back to its normal state. Usually, the watch can not be fixed if it is a water issue. Let’s figure out how to fix Fitbit Sense if it is not working after swimming.
1. Dry your smartwatch
The first step is to dry your smartwatch and remove as much water as possible. Use a towel or tissue to blot the surface and remove any standing water. Once the watch is mostly dry, try turning it on like you normally would. If it doesn’t power on, try pressing and holding the button for 20 seconds. In some cases, this will reset the watch and allow you to power it ON again. If your smartwatch is still unresponsive, it’s time to proceed to the next step.
2. Change swimming mode
If it is an activity tracking issue, try changing the watch settings. Disable the Swimming Mode. It should work after then. Double-tap on the button, and your swimming mode will exit. Remember, it will work only if you are having a tracking issue because of the swimming mode. If your smartwatch doesn’t start after swimming, follow the next steps.
3. Try Charging
Make sure the charging pins are clear, and try charging the watch. If the watch starts charging, then it is fine, and you can use it as usual. However, if the watch does not start charging, you will need to take further steps. One option is to wait for the watch to dry completely and then try charging it again. Make sure your charging pins are clean and there is no dust. Another option is to try using a different charger. If neither of these options works, you may need to contact customer service for your particular smartwatch.
4. Contact the customer support
If none of the solutions above work, your last resort is to contact Fitbit customer support. They may be able to help you troubleshoot the problem or even send you a replacement if your watch is still under warranty. To contact customer support, you can use the live chat feature on the Fitbit website, call them directly, or reach out to them through the Fitbit community forum. You can also send them a message directly from your Fitbit app.
Like many Fitbit users, I am also frustrated that a swim-proof smartwatch can have this issue. But there is a difference between waterproof and water resistance. It is the cause of this issue. For some users, the seal around the screen can not protect the smartwatch. Those who are unlucky can have the issue while swimming.
