Collect the detergent remained on the floor.
16 Remove the ignition key
17 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 also be
performed 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 performed several times in succession.
