What is the Fluff Clean programme and when should I run it?

The Fluff Clean programme is designed to clean the drying cycle of any fluff deposits. After 10 drying cycles, the washer-dryer displays the l (Fluff removal cycle) symbol to indicate this programme should be run, and the electronic cycle counter resets automatically afterwards. To run it, ensure the drum is completely empty, close the door, set the programme selector to Fluff Clean, and press the Start/Pause button. You can also run it at any time without prompting.
