DRAINING THE ECOFLEX SYSTEM

(For machines with EcoFlex system)
Clean the detergent tank as shown in the previous section.
To remove residual detergent from the detergent hoses and pump, proceed as follows.
1. Place the user key (51) in the key reader (41), then press the push-button (42) to start the machine.
2. Check that the detergent quantity indicator (50-G) on the display has at least one segment lit.
3. Press and hold buttons (48) and (49) at the same time until screen (50-M) appears on the display (after approximately 5
seconds).
4. Release buttons (48) and (49) and wait for the countdown timer on the display to finish and the vacuum system to be activated.
5. Collect the detergent remained on the floor.
6. Turn off the machine with the push-button (42) and remove the user key (51).
7. Raise the tank (33), then check that the detergent tank hose (25) is empty; if not, 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 (25) 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 (25) is full but the
system is still empty.
If necessary, the draining cycle can be performed several times in succession.
