Hotpoint FFA60 drain blocked -solution

We have been happpy with the fridge-freezer until very recently when my wife noticed some water collecting in the bottom of the fridge. She dicovered the drain hole at the back (inside the fridge part) was blocked. We tried a wire coathanger to unblock but was unsure whether there was a bend in the tube and did not want to force it. I scanned this website for clues and someone suggested using the wire track used for hanging old-style net curtains. Someone else suggested that the tube might be blocked with ice. So I took a piece of the net curtain track, about 1.5 meters (about 60 pence at local store), connected a small funnel to one end with duck tape, fed the other end down the tube till it bottomed and poured boiling water in the funnel. Within seconds water started to drip into the black plastic drip tray at the bottom rear of the fridge/freezer and the blockage was cleared and we could see the curtain track at the exit of the tube - problem solved! The water in the drip tray is normally evaporated by the heat of the condenser unit.
