Moisture and charge 3 not working

[Jason-408bg]

My Fitbit charge three stopped working the other morning after acting erratically. I had taken a shower with it the previous night.  Examining the Fitbit I did notice there was moisture underneath the sensors on the back of the watch. I let it dry out for a few weeks and if I plug it into charge it powers up but when you disconnect the charger the screen goes black and it doesn’t work. I bought this in December 2018.   Is this repairable or do I need to purchase a new one ?
