Reactivation Salt - Miele PFD 101 Operating Instructions Manual

Commissioning

Reactivation salt

In order to achieve good cleaning
results, the dishwasher needs to
operate with soft water. Hard water
results in the build-up of calcium
deposits on dishes and on the inner
surfaces of the appliance.
Water with a hardness level higher than
0.9 mmol/l (5 °dH – German scale) must
be softened. This occurs automatically
in the integrated water softener. The
water softener is suitable for a water
hardness level of up to 6.5 mmol/l
(36 °dH - German scale).
In order to maintain the functioning of
the water softener, it must be
reactivated regularly. Reactivation
occurs automatically in every ninth
programme sequence. At the start of
the next programme, an additional 4.4 l
of water is required for this process.
Energy consumption increases by
0.015 kWh and the programme is
extended by 3 minutes.
The above only applies to the ECO
programme at a water hardness of
2.5 mmol/l (14 °dH – German scale). For
other programmes and water hardness
levels, the frequency of reactivation will
differ.
In order to be reactivated, the water
softener requires dishwasher salt.
Depending on the water hardness level
(< 3.8 mmol/l, or < 21 °dH – German
scale), dishwasher salt is not required if
combination detergents are being used
(see "Detergents - Types of
detergents").


Damage caused by using
unsuitable salts.
Some types of salt may contain
insoluble components which can
cause the water softener to
malfunction.
Only use special coarse-grained
dishwasher salt or other pure
evaporated salts for reactivation.

Damage to the water softener
from detergents.
Dishwasher detergent will damage
the water softener.
Do not fill the salt reservoir with
powder or liquid detergent.
If the water in your area is very soft
and constantly lower than 0.9 mmol/l
(5 °dH - German scale) you do not
need to add dishwasher salt. The salt
refill indicator will automatically switch
off after the water hardness has been
set accordingly (see "Settings - Water
hardness").
If you only ever use combination
detergent products in your
dishwasher, you can switch off both
refill reminders if you wish (see
"Settings - Refill reminders").
Please make sure that if you stop
using combination detergents, you
refill the dishwasher salt and rinse aid.
Switch the refill reminders back on if
required.
