Fitbit Charge 5 F38 Error Code Guide (Quick Fix)

What This Error Means

F38 on a Fitbit Charge 5 is a general ‘failed to start correctly’ error. The tracker powers up but its software crashes during startup and you get stuck on the F38 screen instead of your clock face.

Fitbit does not publish a public table for this code, but in the field F38 shows up when the watch cannot load its operating system cleanly from internal storage.

Official Fix

Here is the stripped down version of what Fitbit support will ask you to do before they talk replacement.

  • 1. Charge it hard.
    • Snap the Charge 5 into the charger until you see the battery or charging icon.
    • Use a 5V USB wall adapter, not a weak TV or laptop port.
    • Leave it on charge for at least 60 minutes, even if the F38 screen stays up.
  • 2. Clean the contacts.
    • Wipe the gold pads on the back of the tracker and the charger pins with a dry lint free cloth.
    • If they look dirty, use a cotton swab with a little isopropyl alcohol, then let them dry and reconnect.
  • 3. Soft restart from the menu (if the touch screen works).
    • On the tracker, swipe down > tap ‘Settings’ > find ‘Restart Device’ or ‘Restart’.
    • Confirm and wait for the Fitbit logo, then check if F38 is gone.
  • 4. Remove and re add it in the Fitbit app.
    • In the Fitbit app: profile picture > your Charge 5 > ‘Remove This Device’.
    • Close and reopen the app, choose ‘Set Up a Device’, and add the Charge 5 back with it on the charger right next to the phone.
  • 5. Force any pending firmware update.
    • On the Charge 5 page in the app, tap ‘Sync Now’.
    • If you see an ‘Update’ option, run it with the watch still on the charger and the phone nearby until it finishes.
  • 6. Factory reset from the tracker (last official step).
    • On the Charge 5: swipe down > ‘Settings’ > ‘Device Info’ > ‘Clear User Data’ or ‘Factory Reset’.
    • Confirm. After it wipes and reboots, pair it again in the Fitbit app as a new device.
  • 7. If F38 is still there, Fitbit treats it as a dead board.
    • Persistent F38 after a full reset usually means corrupted internal storage or firmware you cannot repair at home.
    • Contact Fitbit support with the steps you already tried and push for a warranty replacement or discount on a new unit.

Is It Worth Fixing? (The Financial Verdict)

  • Fix: If the Charge 5 is under warranty or less than about 18 months old and the case and screen are in good shape, run the steps above and then push Fitbit for a free or warranty replacement.
  • ⚠️ Debatable: If it is out of warranty but otherwise like new and you live in the Fitbit ecosystem, it can be worth taking whatever loyalty discount Fitbit support offers toward another Charge or Versa model.
  • Replace: If the battery was already weak, the screen is cracked, or F38 comes back right after a reset, do not throw more time or money at it; put that cash straight into a new tracker.
