How to replace water tank on Samsung rs21dcns?

Hi

I have a Samsung rs21dcns fridge freezer. The water tank kept freezing up and stopping the water dispenser from working, suggestion from Samsung was to use hot towel and run along the water tank inside the fridge to unfreeze it. This has been annoying but at least working. I now have a problem that the water tank has sprung a leak I think its from too many attempts of heating it up.

I can get the part off the web but does anyone have instructions on how to change the water tank? The pipes vanish inside the bottom of the fridge freezer.

The machine is 1 month out of the 2 year warranty.

Thanks
Will.
