be performed with the detergent tank full of water, thus cleaning the system thoroughly.
It is advisable to perform this type of draining to clean the Chemical Mixing System
from dirt and deposits if the machine has not been used/cleaned for a long time. The
draining cycle can be performed also to quickly fill the detergent supply hose when
the tank is full but the system is still empty. If necessary, the draining cycle can be
repeatedly performed.
