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. Turn on the machine by turning the ignition key (58) to "I".
2. Press the push-button (53). Check that the push-button LED (54) turns on.
3. Press the push-buttons (53 and 59) at the same time, until the LED (54) starts flashing (after about 5 seconds).
4. Release the push-buttons and wait for the LED (54) to stop flashing and for the vacuum system to turn on.
5. Collect the detergent remained on the floor.
6. Turn the ignition key (58) to "0".
7. Raise the tank (19), then check that the detergent tank hose (42) is empty; if not, perform steps 2 to 6 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 (42) 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 (42) is full but the
system is still empty.
If necessary, the draining cycle can be performed several times in succession.
