If its like my american fridge, you should have 2 thin white pipes and a water filter.
One of the pipes connects to a point at the rear of the fridge near the bottom and then connects to one end of the filter.
The other pipe connects to the opposite side of the filter and then to the water main. You might need to get a plumber in to add an extra connection point (connection same as your washing machine)
Hope this helps a bit
