Resolution

Picture 1. “Clean air filter” indicator

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 significantly increases the drying time!
