We recently had to replace our 15 year old fridge freezer. I'm not sure if that is really old in fridge freezer terms, but anyway it became noisy and smelly and eventually thawed out. So we have replaced it. I carefully followed the instructions, that came with the news fridge freezer, of not switching the thing on for six hours after delivery. Cleaned it with sodium bicarbonate and turned it up high initially, but then forgot to turn it down when I put some food and drinks into it.
Tonight, unaware that it was frozen, I opened a bottle of sparkling water and it went everywhere in the kitchen. Once we had cleared up the mess I attempted to get some water out of the bottle and realised that the bottle contained a solid lump of ice.
