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.

Descale the coffee machine regularly depending on the water
hardness level in your area. Descale the machine more frequently in
areas with very hard water. Miele cannot be held liable for damage
arising from insufficient descaling, the use of incorrect descaling
agent or the use of descaling agent which is not of the appropriate
concentration.

Degrease the brew unit regularly with Miele cleaning tablets.
Depending on the natural oil content of the coffee used, the brew
unit can become blocked quite quickly.

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.
