8. Lift the recovery tank, then check that the detergent tank hose is empty, otherwise perform steps 3 to 7
again.
Note:
The draining cycle lasts about 30 seconds, then the vacuum function automatically
turns on, which allows to remove the detergent remained. The draining cycle can also 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 EcoFlex™ 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.
