Re: Is this even legal in the EU?
Again, Whirlpool publicly stated the issue, and a fix / recall.
Same as with car fault recalls - they notify the owners and tell them to bring the item in / book an appointment for an engineer visit.
Realistically, what else CAN they do when a post-sale, post-delivery fault is discovered with a product? If someone was killed before the recall, they'd be susceptible to a charge of corporate manslaughter i suspect. Once they've made the recall public, it's out of their hands somewhat. Samsung are in the position where it isn't out of their hands as they can "force" the recall - difficult to remotely disable a tumble dryer!
