Hi @RemiWester, very sorry to hear about this. 
If there is water inside the device, it will need to be examined at an authorized service centre, so I would recommend that you get in touch with your Local support team and they will assist you further with booking a repair for you, or informing you of the closest service centre in your area.
If you have any questions regarding warranty, local service routines and/or consumer laws, they will assist you with this as well as they are the experts on your market.
I hope that helps!
