We have a Hoover Condenser tumble dryer that is just over 2 years old. It was fine when we bought it but now it takes ages to dry the clothes. There is heat being produced but the inside of the door can be seen to be covered in condensation and it is not drying. I have washed out the condenser element, the filter inside the door, the valve where the collector tank attaches and looked for blockages in the galleries. I am officially stumped!
