In order to achieve good cleaning
results, the lab washer needs to
operate with soft water. Hard water
results in the build-up of calcium
deposits on laboratory glassware and
utensils etc. and in the lab washer.
Mains water with a hardness level
higher than 4 gr/gal (70 ppm CaCO3)
needs to be softened. This takes place
automatically in the integrated water
softener.
–The water softener requires
reactivation salt.
–The lab washer must be
programmed to correspond to the
water hardness in your area.
– Your local water authority will be able
to advise you on the water hardness
in your area.
Where the water hardness fluctuates
e.g. between8-17gr/gal (140 -
310 ppm CaCO3) always programme
the lab washer to the higher value
(17 gr/gal in this example).
The built-in water softener has
settings from1-60gr/gal (20 -
1080 ppm CaCO3).
In the event of a fault, it will help the
service technician if you know the
hardness of your local water supply.
Enter the water hardness below:

Filling the salt reservoir
Only use special coarse grained
reactivation salt with granules of
approx.1-4mm,e.g. Miele Softener
Salt. Do not use other types of salt such
as cooking salt, agricultural grade or
gritting salt. These may contain
insoluble additives which can impair
the functioning of the water softener. If
in doubt consult the Miele Professional
Department.
The salt reservoir holds approx.
2.5 kg of salt.
,Inadvertently filling the salt
reservoir with cleaning agent will
damage the water softener.
Before filling the salt reservoir make
sure that you have picked up the
right packet of reactivation salt.
^Remove the bottom basket from the
machine.
^Unscrew the salt reservoir cap.
Before filling the salt reservoir with
reactivation salt for the first time, you
must fill it with approx. 2.5 litres of
water to enable the salt to dissolve.
Once the lab washer has been
used, there is always sufficient water
in the reservoir.
^Place the funnel provided in position.
^Fill carefully with salt.
As it is poured in, displaced water will
run out.
Water softener
17

^Remove the funnel and wipe any
residual salt off the seal and the
screw threads on the socket.
^Screw the cap back on firmly.
^Run the "Rinse" programme to
remove any traces of salt from the
cabinet.
The programme sequence may be
delayed for a few minutes after the
start of the "Rinse" programme. This
is not a fault. The water softener is
being reactivated.
Add salt indicator
Reactivation takes place automatically
during a programme.
The programme sequence indicator
