Resolution
At the end of each drying cycle in the display, the indicator 
is on to advise to clean the primary air filter (see pictures from 1 to 5). The acoustic signal operates.
Occasionally the indicator may flash to remind you that both air filters should be cleaned: the primary air filter and the secondary air filter (for the secondary filter, see pictures from 6 to 8). The acoustic signal operates.
- Make sure that the air filter has been cleaned.
- Make sure that the air filter is correctly inserted
- To have best drying performances clean the air filters regularly with warm water and afterwards dry them with a towel.
- Clogged air filter increases the drying time and energy consumption!
