Before using the machine for the first
time the following steps must be
completed.
See the respective chapters for
detailed information.
Preparing the water softener
(WES) (Optional)
The water softener unit must be set to
the water hardness level in your area.
The salt reservoir must be first filled
with water and then with reactivation
salt.
,Inadvertently filling the salt
reservoir with dishwashing detergent
will damage the water softener.
Make sure that only water softener
reactivation salt of the proper grain
size is used. Only use Miele water
softener salt.
Cleaning and Care
The filters on the bottom of the wash
cabinet and the spray arms must be
kept clean.
Check and clean them regularly!
Before using for the first time
14

To open the door
^Open the door with the handle.
The door should only be opened during
operation for emergencies, e.g. if items
are knocking together or if a program
fault is indicated in the display (see
"Cancelling a program").
,Do not touch the wash cabinet
surfaces when opening the door
during or directly after the end of a
program. Danger of burns. They
remain hot for some time.
To close the door
^Lift the door upwards and push until
it clicks shut.
Opening and closing the door
15

Applies only for machines with a
built-in water softener.
To achieve good cleaning results, the
dishwasher needs to operate with soft
water. Hard water results in a build-up
of calcium deposits on dishes and in
the dishwasher.
To ensure a steady supply of soft water:
1. the water softener unit must be
correctly programmed, and
2. the salt reservoir must be filled. If the
water hardness level is below 4 gr/gal
(70 ppm CaCO3) the reservoir does not
need to be filles with reactivation salt.
The machine is factory set for a
water hardness level of 19 gr/gal
(340 ppm CaCO3).
If the water supply is harder or softer
than this including below 4 gr/gal
(70 ppm CaCO3) the factory setting
needs to be changed. See "Setting
the water softener" and chart for
settings.
Your local water authority can advise
you of the water hardness in your area.
For fluctuating levels (e.g.8-17gr/gal
[140 - 310 ppm CaCO3]) set the water
softener to the highest setting (in this
example to 17 gr/gal).
Important! The built-in water softener
has settings from 1 gr/gal to 35 gr/gal
(20 - 630 ppm CaCO3).
If the water hardness is above 30 gr/gal
(540 ppm CaCO3) an external water
softener unit (e.g. PG 8597 Aqua Soft
System) is required.

Filling the salt reservoir
Only special, coarse-grained
reactivation salt* should be used in
this machine.
*Available from Miele. Please see
back page for more information.
Do not use other types of salt, e.g. table
salt, agricultural or gritting salt. These
could contain components which are
insoluble in water and could damage
the water softener. If in doubt consult
the Miele Professional Department.
The salt reservoir holds about 3.3 lbs
(1.5 kg) of salt.
,Inadvertently filling the salt
reservoir with detergent will damage
the water softener.
Before filling, make sure that you are
using the proper reactivation salt.
^Remove the lower basket.
^Unscrew the salt reservoir cap.
,Filling the salt reservoir with
salt for the first time:
First fill the reservoir with approx.
0.5 gal (2 liters) of water.
Refilling the salt reservoir with
salt:
If there is still water in the tank, run
the "Drain" program first.
^Place the supplied funnel over the
salt reservoir.
^Carefully fill with reactivation salt.
Displaced water will run out as it is
being filled.
^Clean any excess salt from the
threads of the reservoir opening.
^Screw the cap on firmly.
