Cleaning and care

Disconnect the coffee machine from the power supply before
cleaning.

Clean the coffee machine and the milk flask (supplied as standard,
depending on model) daily, particularly before using for the first time
(see "Cleaning and care").

All parts of the milk system need to be cleaned thoroughly and
regularly. Milk contains bacteria which proliferate rapidly with
inadequate cleaning.

Do not use a steam cleaner to clean this machine. Steam could
reach electrical components and cause a short circuit.

If you use hard water (> 20 °dH / 3.6 mmol/l) or if the coffee
machine is used intensively, it may be necessary to descale the
machine manually in addition to automatic descaling.

If you are descaling the coffee machine manually, carry out
descaling regularly depending on the hardness level of your water.
Descale the machine more frequently if you use 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.

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.
