Dishwasher hose did this after just three years. Lucky we spotted it before it blew, otherwise would have been very expensive. In the second picture you'll see the very expensive braided metal replacement hose made in Germany, cost me thirty euro but i am hoping will not suffer from the same problem. Water hoses are funny things, some last just a few years before getting aneurisms like this one did, for most it's the washers which go and it's a slow but safe leak. And there appears to be no way to predict which hoses will be perfect for twenty years, and which last just a few.
