Cleaning the CAPPUCCINO / CAFFELATTE nozzle

The nozzle and valve must be

cleaned immediately

to ensure

optimum milk froth

. Even the slightest milk residue will impair the

frothing up result!

Note!

Dried-on milk residue is very difficult to remove.

►

After each frothing up process, switch to

Draw hot water

and

flush the

frothing up nozzle

with hot water.

►

Clean

daily

by placing the hose in a glass or receptacle

containing hot water and repeat the (frothing up) process –
except now with drawn in water instead of milk. Milk residue is
dissolved and flushed out.

►

To clean

thoroughly

, disassemble all parts and clean with a

soft brush in a mild detergent solution.

Clean particularly inaccessible locations with a blunt needle.

Rinse all parts with hot water and dry.

Parts are dishwasher-proof.

Note!

When re-assembling the parts, ensure that the smooth
end of the milk hose is connected to the frothing-up aid.
Insert the notched end into the milk container. Connect
all parts firmly together. Ensure that there are no gaps
between the individual parts.
