I have the same problem. I think what is happening is this:
1) Dew drops of water form at the back of the fridge compartment.
2) These run down into the drainage channel.
3)a)The drainage channel is not drinaing the water away fast enough so the water spills into your salad boxes
AND/OR
b) The drain doesn't lead anywhere and so it just dribbles the water on to your floor.
I'm guessing the only way to solve this last part is to get a plumber to hook your fridge up to a drain
As for water dribbling into the salad boxes, either
a) Clear the drain (I'm not sure how to do this but I'm sure there's instructions online)
AND/OR
b) Flick the switch located just above the door. The switch in question has an icon of two water droplets on one side and an icon of just one droplet on the other side. I'm guessing this has something to do with the rate at which water droplets form at the back of the fridge.
Anyway if you find a manual or something I'd be much oblliged.
