Possible cause and remedy
The brew unit cannot move into the correct position or it is
dirty and the ground coffee cannot be processed.
^ Try to remove the brew unit (see "Cleaning and care –
Brew unit").
^ If you can, take it out and clean it (see "Cleaning and care
– Brew unit").
^ Push the coffee ejector of the brew unit into the correct
position (see illustration).
^ Replace the waste container and the water container in the
coffee machine. Do not replace the brew unit. Close the
front of the coffee machine and switch the coffee machine
on with the On/Off sensor
The brew unit motor will now be initialised.
^ When "Insert the brew unit" appears, open the front and
replace all the parts in the machine. Close the front.
If you cannot remove the brew unit:
^ Switch the coffee machine off with the On/Off sensor
Wait for approx. 2 minutes and then switch it back on
again.
There is a fault with the automatic spout adjustment.
^ Confirm the message with OK.
The automatic spout adjustment will be deactivated during
drink preparation whilst the machine remains switched on.
