Warning and Safety instructions
Cleaning and care

Clean the coffee machine and the milk flask daily, particularly
before using them for the first time.

All parts of the milk system need to be cleaned thoroughly and
regularly. Milk contains bacteria which proliferate rapidly with
inadequate cleaning.

If you do not make use of the automatic descaling and cleaning
functions, you must regularly run the maintenance programmes for
cleaning the milk pipework and the brew unit, and for carrying out
descaling. Miele cannot be held liable for damage that results from
not cleaning and/or descaling the machine properly, or from using
the wrong cleaning/descaling agent or an unsuitable solution
concentration.

Do not use a steam cleaner to clean this machine. Steam could
reach electrical components and cause a short circuit.

Used coffee grounds should be disposed of with the organic
rubbish or on the compost heap. Do not empty them down the sink,
as they could block it.
