Page 5
IMPORTANT SAFETY INSTRUCTIONS
Only use cleaning agents
formulated for special processes
and approved by Miele for use with this
machine. Use of unsuitable cleaning
agents could adversely affect the
components of the machine.
Pre-treatments with detergents can
create suds, as can certain rinsing

cleaning only, use low-sudsing
detergents which have been approved
by Miele. Suds can have an adverse
effect on the cleaning process.
Where a chemical additive is
recommended on technical
application grounds (for example, with
a cleaning agent), this does not imply
that the manufacturer of the machine
takes responsibility for the effect of the
chemical on the material of the items
being cleaned. Please be aware that
changes in formulation, storage
conditions, etc, which may not be
published by the chemical producer,
can have a negative effect on the

Water softener
To avoid the build-up of calcium
deposits on glassware and the
machine, the water may need to be
softened (where the supply hardness
exceeds 107 ppm CaCO
).
3
To ensure a steady supply of soft water,
the water softener must always be:
1. correctly set (programmed) and
2. regenerated with salt as soon as the
"Recharge Softener" indicator
illuminates.
The water softener should be set to
correspond with the water hardness
upon installation of the machine.
Your local water authority can advise
you on the water hardness in your area.
Setting the water softener
The machine is set at the factory for a
water hardness setting of 19*,
corresponding to 339 ppm CaCO
your water supply is harder or softer
than this, the setting of the controls
should be changed.
Where the water hardness fluctuates
e.g. between 160 - 310 ppm, always
program the machine to the higher
value, 310 ppm in this example.
