We've had a letter for the tumble that we bought in 2005.
After about 10 months it kept smelling as though it would burst into fire at any moment. This and the massive rise in our electric bill led to us chucking it into the nearest skip vowing never to own one ever again.
Wish id contacted them to get a refund at the time
Oh well you live and learn!
Im told the combined washing machine / tumble dryer units are the most dodgy appliance you can own as regard to fire risk.
