My dryer stops within a few minutes of starting and displays fault code F09. The dryer then stops. This happens irrespective of whether there are clothes in the dryer or not. It is the same for any setting.
I had an engineer come today who said it was because one fo the filters was blocked causing the machine to over heat. If you look at the bottom left of the machine, there is a little door to open. There is another filter in their that i failed to regularly clear. The gentleman said it needs emptying after every load and once every week he suggested taking a hosepipe to it, making sure it is thoroughly cleaned. i hope you find this useful.
