Washing machine Dimensions

I just had a phone call from an old friend asking about the depth of washing machines. They currently have a Whirlpool machine that is only 520mm deep and has been fitted like an integrated appliance with a cupboard door in front of it. He reckons there is room for up to 560mm depth to the new machine but asks if there are any currently made machines that would fit. I know Zanussi used to offer a reduced depth version of the Nexus, is there an equivalent machine still available?
