is not dirty. If necessary, remove coffee deposits with a sponge.
• Remove the residues with a vacuum cleaner.
Cleaning the brewing unit
The brewing unit must be cleaned regularly to avoid the build-up of
coffee encrustations which could cause malfunction.
The brewing unit can only be taken out when the appliance is
switched off by pressing the on/stand by button (Aa). Otherwise,
the coffee machine may be seriously damaged.
Proceed as follows:
1. Turn the appliance off by pressing the on/stand by button (Aa) (do
not switch off the main switch or unplug) and wait for the display
to go off.
2. Open the service door.
3. Remove the drip tray and the waste coffee container.
4. Press the two red release buttons inwards and at the same time pull
the brewing unit outwards
Clean the brewing unit under running tap water without using
detergent. Never clean the brewing unit in the dishwasher.
Do not use washing up liquid to clean the brewing unit. It would
remove the lubricant applied to the inside of the piston.
5. Soak the brewing unit in water for about 5 minutes, then rinse.
6. After cleaning, replace the brewing unit (L) by sliding it onto the
internal support (S) and pin (P) at the bottom, then push the PUSH
symbol fully in until it clicks into place.
N.B.! If the brewing unit is difficult to insert, you must first adapt
it to the right dimensions by pressing it forcefully from the bottom
and top.
7. Once inserted, make sure the two red buttons have snapped back
out, otherwise the service door cannot be closed.
