containing hot water and repeat the (frothing up) process – except now with drawn in water. 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. Attention: 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 (A) into the milk container.
Connect all parts firmly together. Ensure that there
are no gaps between the individual parts.
