Note:
If your water hardness is either 4 or
5, we strongly recommend you change
to an alternate water source. Filtered,
bottled spring or low-mineral water will
extend both the life of your built-in filter
and descale intervals as well as superi-
or taste. Please ensure to test the water
hardness of the alternative water source
you've chosen and input the measured
value into the Espresso Machine accor-
dingly. See: ›Water Hardness (Hrd)‹.
Avoid using overly filtered water, like
RO water unless some mineral content
is being added back to the final water.
Never use distilled water, or water with
no or low mineral content as this will
affect both the taste and the functioning
of your Espresso Machine.

Filling the Boilers

After setting the water hardness, a pum-
ping/vibrating sound will be heard indi-
cating empty boilers are being filled with
water for the first time. The main LCD dis-
play will display the current boiler tempe-
rature and flash "HEATING".
