Problem
The coffee is not hot
enough.
The milk is not hot
enough for making cap-
puccino or latté macchi-
ato etc.
The milk has an
unpleasant taste/odour
after texturing.
No or not enough crema. The coffee beans are
Possible Reason
The cups or the portafil-
ter were not pre-heated.
The appliance did not
reach the operating tem-
perature, before brewing
started.
The group head has
not been purged before
extraction.
The milk is tempered suf-
ficiently, when the bot-
tom of the milk jug gets
too hot for touching it.
The used milk is not real-
ly fresh.
Residues of milk are on
the hot water / steam
wand, probably within
the stainless steel tube.
The water within the
water tank is stale.
The water system must
be purged.
stale.
The coffee powder has
been tamped too tightly.
The Solution
Rinse the cups using the hot water function and place
them on the warming tray. Rinse the portafilter, before
wiping the portafilter dry and filling in coffee powder.
Always wait until the POWER button is illuminated con-
tinuously, before starting an extraction via the brew
function.
Purge the group head by activating the brewing func-
tion without the portafilter installed. This way, the parts
of the group head will be pre-heated and the coffee
temperature will be increased.
Increase the time duration for texturing milk, thus incre-
asing the temperature, by pressing more steam into
the milk.
Only use fresh, cold milk for texturing.
Always clean the hot water / steam wand in time
(see: 'Cleaning the Hot Water / Steam Wand'). After
each usage, wipe off residues of milk from the hot
water / steam wand and purge the hot water / steam
wand by shortly operating the steam function. This
way, you reduce the build-up of dried-on milk.
Each day before use, empty and refill the water tank
with fresh, cold tap water. Regularly clean the water
tank (see: 'Cleaning the Water Tank').
This can happen after an elongates period of storage
and when using the appliance only rarely. Clean the
appliance (see: 'Care and Cleaning'), especially purging
the water system thoroughly (see: 'Purging the Water
System').
Use freshly roasted coffee beans with a 'Roasted On'
date and consume 3 weeks after that date, at the
latest (see: 'Selection and Storage of Coffee').
Reduce the pressure, applied for tamping the coffee
powder in the filter basket.
