Fitbit accidentally dropped into water

Hi,

You may be able to fix it yourself.

As you know water and electronics and electricity are not a good mix.

The water causes corrosion and provides circuit paths for the electricity which were not in the watch’s operating design and could damage the components.

First remove the battery as soon as possible from the watch to minimize any further damage.''

Then you need to dis-assemble the rest of the watch and clean all the affected parts using Isopropyl Alcohol 90%+ (available at most pharmacies) to remove all traces of corrosion and water. Do not use "rubbing alcohol" as in some cases this is only 70% IPA or less, can contain scents and other ingredients and is not as effective. If you do check the label to verify the amount of IPA

Here is a link that describes the process.

Electronics Water Damage

As always with electronics, especially surface mounted PCBs be gentle when handling and especially when brushing away the corrosion. You do not want to remove any components from the board.

Hopefully after you have done all this the watch might possibly work correctly again.

Here is a link to the ifixit guide(s) for repairing your watch.

If this process seems too daunting, take your watch to a reputable, professional electronics or mobile phone repair service, experienced in water damage repair and ask for a quote for a repair. If you decide to do this, do it sooner than later.
