If this unit is only a year old and is already faulty, it shouldn't be your problem. Even if it's over a year old, and so just out of warranty, clearly you can expect more than a year's efficient use from your purchase. Take it up with the retailer you bought it from, under the Sale of Goods Act. It's his responsibility to sort out the problem. You'll probably be fobbed off, but don't take no for an answer - the law is on your side!
