CLEANING THE GROUP HEAD

NOTE
The sealing ring of the group head lays around the splash screen at the bottom of
the group head. With residues of coffee powder sticking to the sealing ring, the
portafilter cannot be installed leak-free at the group head and the hot water runs
out at the rim of the portafilter. For checking the splash screen and sealing ring,
we recommend to lay a small mirror under the group head.
After each coffee making session we recommend to run water through the group
head via the extraction function but without any coffee powder, to rinse out most of
the residual coffee particles and the oils. When the machine is ready for operation,
simply press the 2 cups button and let the machine operate.
We recommend regular, thorough cleaning of the shower screen and sealing
ring (every month) for removing any residues of coffee powder and oils. A perfect
moment is the cleaning procedure for the filter basket via a cleaning tablet.
CAUTION
– Do not use any hard or sharp-edged objects or cleaning utili-
ties for cleaning the shower screen and sealing ring within the group head to avo-
id damage. With the sealing ring damaged, the connection between filter basket
and group head will be leaking. Do not use any cleaning agents. Only use clear
water.
1. Switch off (all buttons get dark), unplug, and leave the machine cool down.
2. Wipe the splash screen and the sealing ring of the group head via a soft cloth,
moistened with clear water. The cloth stays clean, when all residues are remo-
ved.

CLEANING THE DRIP TRAY

The drip tray should be removed at the latest, when the filling indicator comes up.
Empty and clean the drip tray daily after switching off the appliance.
IMPORTANT - The water in the drip tray may be hot. Handle with care. Carefully
pull out the drip tray to avoid spilling water onto the base of the appliance. This
holds especially when the drip tray is full up. For cleaning, do not use abrasive
cleaners, pads, or cloths, which could scratch the surfaces.
1. Holding the drip tray level, carefully pull the drip tray out of the base of the appli-
ance. Remove the cup tray and the red float of the filling indicator.
2. Empty the drip tray in the sink. Dispose of residues of coffee powder in domestic
waste.

3. Wash the drip tray, float, and cup tray in warm dishwater using a soft cloth.
Wipe dry.
4. Put the float of the filling indicator onto the post in the drip tray.
IMPORTANT - Ensure to insert the cup tray in correct orientation. Turn the wide
holes to the left rear side of the drip tray. Otherwise, the filling indicator gets
blocked. If the cup tray does not lie stably, turn the float by 90° to make it slip
down. Then try again.
5. Replace the cup tray. To ensure correct functioning of the filling indicator, check
whether the filling indicator can move freely up and down without sticking under
the cup tray. If required, turn the cup tray accordingly.
6. Re-place the drip tray by carefully pushing the drip tray into the base of the appliance.

CLEANING THE HOUSING AND WARMING PLATE

IMPORTANT - Do not use abrasive cleaners, pads, or hard cloths, which could
scratch the surfaces.
The exterior of the appliance, power cord, and warming tray can be cleaned via a
soft, damp cloth. Polish with a soft, dry cloth.

DESCALING THE APPLIANCE

To ensure optimum performance and for protection against damage the appliance
must be descaled regularly (every 2-6 weeks). The required frequency of descaling
depends on the water hardness of the water used and the frequency of usage of
the machine. Information on the water hardness may be given by your local water
works or the bottling plant. For descaling strictly adhere to the instructions given in
this section.
CAUTION
– Only use the GASTROBACK Descaler to avoid damage to
your health and/or damage to the machine due to harmful chemicals. There is no
liability claim of the purchaser for any damage caused by excessive lime deposits
within the machine or by the usage of unsuited descaling solutions.
WARNING
– During the descaling process hot water could drip from the
group head and steam wand. After descaling, always empty and rinse the drip
tray (see: 'Cleaning the Drip Tray'). Always ensure good ventilation during desca-
ling. Do not aspire the vapours of any type of descaling solution to avoid inju-
ries to your aspiration tract.
