Faults with automatic cleaning and/or descaling
Problem Possible cause and remedy
After switching on, a
message appears
informing you that
automatic cleaning and/
or descaling could not
be carried out.
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.
The appliance door was not closed.
Confirm the message with OK.
Make sure that the coffee machine is ready to use
before the next automatic cleaning and/or
descaling process.
The coffee machine was not switched off at the start
time.
The automatic maintenance programmes are only
started if the coffee machine is switched off.
Confirm the message with OK.
Change the start time if necessary.
Descale the appliance
appears in the display
even though a
descaling cartridge
which is ready to use is
fitted. Drinks cannot be
made.
Depending on the water hardness level in your area
and your usage patterns, 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”).
