What a timely post. I have always known that you had to unblock the hole thingy at the back of the fridge every now and then, but recently there's been a bit of a smell around the fridge. We've pulled it out and cleaned underneath it but it was still there. I didn't realise that there was a drip tray at the back and having just had a look it has a fair bit of yukky water in it, the trouble is I can't get it out to clean it thoroughly so have just had an enjoyable!!! ten minutes trying to soak it all up, it still isn't totally clean though but hopefully it will help if I do it regularly.
