Unfortunately my excitement was short-lived. After waiting 24 hours for the gasses to settle I finally turned her on last night. For the first 20 minutes all was fine, she was making a quiet humming noise….
…… Then she got angry and started making this noise. If you listen to the complete track the silence in the middle is when I open the fridge door. Now I’m not a fridge engineer, but I’ve got a fairly good idea that this isn’t right – especially when you’ve spent £900. Whatever happened to quality checks?

I phoned John Lewis this morning and they have arranged for an Engineer from Siemens Bosch to call out on Monday. The guys over at the UK White Goods Forums think its sounds like the evaporator fan may have been dislodged during transit or it is hitting some insulation.

UPDATE: It was the evaporator fan, it just needed reseating. The engineer from Siemens Bosch was very helpful and fixed it in 5 minutes. Its be fine since!
