Possible cause and remedy
This is not a fault.
The drip tray has probably been removed without the
waste container being emptied.
Removing the drip tray resets the internal counter for
emptying the waste container.
 Always empty the waste container if you remove
the drip tray.
The brew unit is not in the correct position because
the appliance door was opened during the brewing
process, for example.
 If necessary, move the handle on the brew unit
back to the start position. Close the appliance
door.
 Switch the machine off with the On/Off  sensor.
 Disconnect the electricity supply by switching off
at the wall socket and withdrawing the plug, or
switching off the mains circuit breaker.
 Wait approx. one minute before reconnecting the
coffee machine to the electricity supply and
switching it on.
This will initialise the brew unit motor and put it back
into the start position.
 If necessary, repeat these steps.
The central spout has a blockage.
 Rinse the coffee pipework (see "Cleaning and care
- Rinsing the appliance").
If there is still no coffee coming out, or coffee is only
coming out of one side:
 Dismantle the central spout and clean all parts
carefully.
 Make sure all parts are reassembled correctly.
The milk pipework is blocked.
 Clean the central spout, taking particular care to
clean the cappuccinatore and milk pipes
thoroughly with the cleaning brush.
