first two seconds after inserting the plug into the socket. (Please make sure to avoid any serial connection

The Ntc sensor must work correctly; if there is a failure on NTC (Ntc disconnected or in short circuit) the
operation cannot be performed and the L26 will blink (turn off the machine and repair before do Steam-

The DREGDRAWER must be in place and the DOOR must be closed; if someone is not in place the operation
cannot be performed and the L25 will blink. To start again the operation insert drag drawer and close
service door.
If these 2 conditions are respected the machine will start automatically the Steam Out process showing L18
and L20 flashing in series.
If, during the Steam Out, the Door is opened or drag drawer is removed L25 will be switched on.
To start again the operation insert drag drawer and close service door.
