Cleaning (Daily)
1. Cleaning the Diffuser Screen.
During
the
discharge
operation
(subsequent to coffee brewing), small
amounts of coffee grounds may slowly
build-up on and obstruct, even partially,
the diffuser screen. Turn off the machine
and remove the diffuser screen by
unscrewing the diffuser screw. Soak in
detergent powder liquid following the
instructions of detergent manufacturer.
Rinse thoroughly with clean water. Install
and run hot water through the group
head several times with the screen
installed.
2. Cleaning the Brewing System.
Insert the blind filter into portafilter
and put the correct amount of espresso
cleaning product (following the product’s
instructions) into the filter, engage the
portafilter into the group you want to
clean.
• Press the brewing button for said group,
as if you were making a regular cup of
coffee. Stop the water after about 15-20
seconds.
• Start and stop the group several
times until you notice clear water being
released instead of soapy water when
you remove the portafilter.
Do not remove the portafilter when
group is actually brewing water.
• Rinse the group using a normal filter
in the portafilter, by running hot water
through it several times.
3. Cleaning filter baskets and portafilters
With daily cleaning of the stainless steel
filters and portafilters it is sufficient to
clean them with water and a cloth or
appropriate brush. Otherwise, using an
espresso cleaning product, following the
product’s instructions put the correct
dose in about 1/2 a litre of water inside a
heat-resistant container and heat.
• If using stainless steel portafilters
with snap-on spouts remove the spout.
Immerge filters and metallic parts of
portafilters (not handles) in the hot
solution and leave them submerged for
about 30 minutes.
• Rinse thoroughly with clean water and
run hot water through the group several
times with the filter and portafilter
engaged.
4. Cleaning the Drain Box.
Remove the drain box assembly and wash
each of the components with hot soapy
water. Rinse thoroughly and reinstall the
drain box assembly. All components of
the drain box assembly are dishwasher
safe.
