Airwheel in Water, how deal with it.

HI eveyone!

My airwheel felt in the water.... it's been1 day now, I tried to let it dry over an heater and tried it few minutes ago but the light are going on and then shutting down... So for now it's not working but it seems it's not "dead" either...

I tried to open it up to let it try but it didn't work... So do you have suggestion? I don't really not what more to do and I hope it's going to work again,

Thank you!
