Washing machines cost between $250 and $2,050; dryers cost anywhere from $200 to $1,750. http://www.kitchens.com/product-guide/washers-dryers/washer-...
And people complain the average machine does not last 10 years. So, unless you found the cheapest washing machine from 1950's it's not exactly a direct comparison.
Also, a sidenote - that Hotpoint washer comes with a free 10 year parts warranty - you have to pay for the engineer to come and install it, but Hotpoint will replace any part of the washer for free, or give you a new one if they can't fix it.
