The icemaker in my GE fridge has leaked since we got it. Just a little, But every time it fills the mold, some water drips down into the container of ice, causing the cubes to stick to the container and to each other. I've removed the icemaker and determined that there's no leak in the mold. The water line enters the inlet cup through a hole in the side of the cup - no gasket or anything, and I suspect that some water escapes through that hole as water squirts into the cup. I'd like to try filling in the hole areound the inlet line. Is there some sort of putty that is safe for potable water that would hold up in the freezer?
