I would say that it depends. Regular maintenance of course is on the tenant, if the washing machine is not mine and it brakes down I would not repair it without first discussing it with the landlord. If it broke down because of my misuse I'm fine paying, but it is just regular wear why should I ? I'm paying a premium for a furnished house after all.

Of course the best is to make it clear at the moment you rent, not when the issue arise.
