The drying system is based on the principle of forced air with condensation by water jet. The drying 
capacity is equal to about half the maximum load of dry washing. Therefore, when a full load is washed, 
two drying cycles will be necessary. If a half load is washed, however, drying may be carried out 
automatically at the end of the washing cycle. 

During the drying phase, the drum rotates in alternate directions at low speed. 

The fan ducts the heated air from the heating elements into the tub, which removes the humidity from the 
washing. 

The jet of cold water, coming into contact with the humid air, generates a heat exchange which condenses 
the humidity. Cold, dry air is ducted to the fan and then again heated by the heating elements and re-
circulated inside the drum. 

The cooling water and the condensation are expelled by the drain pump. 

During the final minutes of the drying cycle, the heating elements switch off, but the fan continues to 
function in order to complete the drying phase.
