won't work vs doesn't work

[Winwin2011]

1. The shower won't work.
2. The shower doesn't work.

Is there any difference when we are using "won't" and "doesn't" in the above sentences? What does "won't i.e will not " mean in the above context? We usually use "will" for the future.

Thanks for your help!

Both are possible. 'Will/won't' can be used of willingness. John won't tidy his room (He is unwilling to do it, refuses to do it). If we use 'won't work' of an inanimate object, we are perhaps suggesting that that object is displaying stubbornness.

Thanks a lot 5jj.

Does "stubbornness" mean 'difficult to move'?
