92
Cause and remedy
If you have made drinks with milk, the milk pipe must
be pushed into the drip tray cover and when the
machine is switched off, the message about this in
the display confirmed with OK.
All removable parts, such as the water container, drip
tray, brew unit or central spout, must be fitted.
The water container must be filled with water at least
up to the descaling symbol  (at least 500 ml water).
The appliance door was not closed.
 Confirm the message with OK.
 Make sure that the coffee machine is ready to use
before the next descaling process.
The coffee machine was not switched off at the start
time using the On/Off button .
The coffee machine pipework will only be filled with
descaling solution when the coffee machine is
switched off.
 Confirm the message with OK.
 Change the start time if necessary.
Depending on the water hardness level in your area
and your usage behaviour, the coffee machine needs
to be descaled using the maintenance programme
occasionally.
For this you will need to use Miele descaling tablets.
 Descale the coffee machine using the
maintenance programme (see "Cleaning and care -
Descaling the appliance").
