Cleaning and care

Clean the coffee machine and the milk flask daily, particularly
before using 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
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.

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.

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.
The following applies to appliances with stainless steel
surfaces:

Do not adhere stickers, adhesive tape or any other adhesive
materials to stainless steel surfaces. The coating on the stainless
steel surfaces will become damaged and lose its protective
properties against soiling.

Stainless steel scratches very easily and even magnets can cause
damage to the surface.
