Hi, I have a slave 2.1 doser that I was using with my KH Director ( on top of the doser). I had been cleaning and was putting things back together and testing everything when some aquarium water leaked on to the top of the doser unit. I wiped it up and though it was fine until a couple of minutes later it quit working and started smoking. When I disassembled it, the water had gotten in at the edge of the cover and the dripped down unto the main board. I had thought the covers were sealed to prevent this from happening.

So can you just replace the board or do you need to replace the whole doser now?

Thanks
