The Easy Solution
Ensure to leave sufficient space between the tamped
coffee powder and the rim of the filter basket (2-3mm).
Scrape off surplus coffee powder (see: 'Operation / Tam-
ping the Coffee Powder'), then tamp the coffee powder
and wipe the rim of the portafilter and filter basket clean
again.
Do not apply too much pressure when tamping the coffee
powder in the filter basket (see: 'Tips for Best Results').
Get in contact with an authorized service centre for exa-
mination and repair. Do not poke in the group
head with any hard or sharp-edged objects.
For cleaning the group head, only use a soft cloth or
SOFT nylon brush.
Flush the water system with cold tap water or low-
mineral, non-carbonated bottled water (see: 'Tips for Best
Results / The Water Quality' and 'Before First Use /
Flushing the Water System').
Fill a sufficient amount of water into the water tank
(between MIN and MAX filling line). Do not let the
machine pump the water tank completely
empty.
Push the water tank down at the back of the appliance
until the water tank lid levels up with the top of the
appliance (see: 'Operation / Filling the Water Tank').
Turn the selection dial to the vertical standby position.
For producing steam, the appliance heats the water sys-
tem to the significantly higher steam temperature. Wait,
until the extraction temperature is reached again. The
extraction starts automatically.
Only use coffee powder suited for espresso machines
(see: 'Tips for Best Results').

ped too firmly.
Air in the water system.

watery.
You applied too little pressu-
re when tamping the coffee
powder in the filter basket.
You started the extraction
via the wrong espresso
button.
The Easy Solution
Leave at least 2-3mm of free space between the tamped
coffee powder and the rim of the filter basket (see: 'Ope-
ration / Tamping the Coffee Powder').
Reduce the applied pressure when tamping the coffee
powder (see: 'Tips for Best Results').
Flush the water system (see: 'Before First Use / Flushing
the Water System').
Reduce the intervals for descaling the espresso machine
(see: 'Care and Cleaning / Descaling the Appliance').
If the water hardness in your area is extremely high, it
may be better to use low-mineral, non-carbonated table
water (see: 'Tips for Best Results / The Water Quality').
Clean the filter basket (see: 'Care and Cleaning / Tho-
rough Cleaning of the Portafilter and Filter Basket').
Always remove used coffee powder immediately from the
filter basket. Thereafter, rinse the filter basket with hot
water (see: 'Operation / After the Extraction').
If the problem persists after cleaning, replace the filter
basket. Contact your vendor.
Use fresh coffee beans and coffee powder with a grind
size suited for espresso machines. Adjust the grind size of
the grinder somewhat finer (see: 'Changing the Default
Values / Setting Up the Grinder').
Use at least 1 measuring spoon of coffee powder (see:
'Operation / Filling in Coffee Powder Manually' or 'Ope-
ration / Using the Grinder'). If required, adjust the grin-
der of the espresso machine accordingly (see: 'Changing
the Default Settings / Setting Up the Grinder').
Apply a sufficient pressure via the provided tamper (see:
'Operation / Tamping the Coffee Powder').
After filling the 1 cup filter basket with the appropriate
amount for 1 cup, you should start the extraction via the
1 cup button (see: 'Operation / Starting the Extraction').
