Lots to read,its in there somewhere,
Samsung will now fix it for FREE.
Just fixed my noisy Samsung, I thought it was the usual iced up fan thing.
Took the cover off it and no .. it wasnt iced up.
It was a pipe rattling on the water tank at the back,found it after taking off that cover.
Secured the pipe and it rattles no more :).
Saved a call out and god knows what con :)
