Warning and Safety instructions
Cleaning and care

Disconnect the coffee machine from the power supply before
cleaning.

Clean the coffee machine daily, particularly before using it 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 clean the machine with a steam cleaner or immerse it in
water as this will damage the machine. Steam or water could reach
the electrical components and cause a short circuit.

Avoid spillage on appliance connectors.

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
agents or the use of a 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.
