I'm sorry I can't see a number on my Liebherr Premium fridge freezer but please can you tell me how to adjust the temperature of the fridge. It is on 0 and when I try to change it to 5 ( I think this is it what it should be?) it just flashes for a while then returns to 0. Please advise me I have all my Christmas food in there!
