Hello, thank you for your suggestion, on the basis of which the supplier contacted us and would like to respond below.
"Hello, for the milk frothing to work properly, you need to clean the milk passage regularly so that no milk residues remain. We recommend that after each use of the milk unit you remove the tube from the milk container, place it in a cup of clean water and start frothing in the prepared cup. This will clean the milk unit and make it ready for the next frothing or latte brewing. If you need a more thorough cleaning, please contact us at
[email protected] and our colleagues will be happy to send you a detailed procedure. Regards Team Sencor"
Please do not hesitate to contact us in case of need. Thank you and have a nice day, Ondřej - Alza expert
