CI Pad is completely sealed – the plastic parts are glued shut to prevent water ingress (which is one of the reasons for repairs being difficult, because we literary have to rip the CI Pad open and consequently replace the plastics).
As difficult as it is to repair, it makes the CI Pad also quite water resistant.
In normal case the only way water can seep inside the CI Pad is improperly closed port flap / seal. There is whole section about that in the User manual – you really need to push the port flaps completely in to make them flush the the CI Pad body. When they are new, it actually takes quite some force to push them into the correct position and e.g. the SD card and SIM flaps hold in place so well (when they are inserted properly), that it is not really easy to even make them out again.
So we are sorry to break it to you, but if water got inside your CI Pad, it is near certain that you are to blame for not closing the ports properly or not replacing them when they got damaged.
To give you a better idea, let us ask a question: Where do you think there are most water damage cases on the planet? Yes, we heard you! You just whispered Norway (or other country with frequent and heavy rains). Nope. The correct answer is Spain – one of the most arid counties in Europe and that for sure tells the story where most water issues come from (not the device, but the user;-).
It could also be that if you keep opening and closing the port flaps frequently, they are worn out or damaged. If you suspect this, please get a replacement – they are available on our eshop as spare parts.
