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

The Fluff Clean (limp. pelusas / fios) programme is designed to clean the drying system of any fluff deposits, and the washer-dryer will indicate when it needs to be run by flashing the l symbol on the display panel. To run it, ensure the drum is completely empty, set the programme selector to Fluff Clean, and press the Start/Pause button. The electronic cycle counter is automatically reset once the programme starts. (Page 14)
