How to deal with a water damage?
Scale got wet in the bathroom and does not start anymore.
Do not turn on the device or try to charge it.
Next open the device and disconnect the battery from the motherboard so as to minimize any further damage.
Here are a couple of links that may be of some help.
If the corrosion on the board is bad, try cleaning with Isopropyl Alcohol 90%+ (available from electronics parts stores) and a soft brush. Also if possible do not use “rubbing alcohol” unless there is no purer IPA option available. Rubbing alcohol is usually only 70% IPA or less, can contain scents and is not as effective as purer IPA.
As always with electronics, be gentle when handling and do not brush too hard to remove the corrosion. You don’t want to remove any components from the board.
Good luck with the repair.
If none of the above work, the components inside your reset button on the side of the unit are probably too corroded. You’ll need a replacement part, which Withings won’t send you. This is a basic design error that Withings are ignoring. This is the 2nd product I’ve had design issues with. Take from that what you will but this user will never be buying from them again.
Mine went crazy, getting stuck in a loop of continually restarting itself. I put it in the hot press for a few days after which the nature of the faults changed somewhat. It would show the weight only, then cut out. As an added bonus the info on the screen was also upside down. So it probably was water.
I reset the scale to factory settings according to Withing service instructions as follows.
Since doing this, the scale is performing normally. It now needs a new battery which is why I am on this site. Hope this helps someone.
