For good cleaning results, the machine
requires soft (calcium poor) water. If the
mains water is hard, white deposits will
form on the load and the walls of the
rinsing chamber. Softening is required
if the hardness of the mains water
exceeds 4 °d (4 gr/gal). This takes
place automatically in the built-in
softener.
– The softener requires regeneration
salt.
– The machine must be programmed
exactly to the hardness of your mains
water supply.
– Information on the exact hardness of
the mains water can be obtained
from your local water authority.
The machine is set at the factory for a
water hardness level of 19 °d
(19 gr/gal).
If the water supply is harder or softer
than the factory setting (including
below 4 °d [4 gr/gal (0.7 mmol/L)],
the setting will need to be changed
in the electronic control.
Your local water authority will advise
you on the water hardness in your area.
Where the water hardness fluctuates
e.g. between 8 - 17 °d (8 - 18 gr/gal),
always program the machine to the
higher value, 17 °d (18 gr/gal) in this
example.
If there is a fault, it will be helpful to
know the water hardness of the local
water supply.

Setting the water softener
The water softener must be set by the
service technician after installing the
machine to reactivate the water
softener according to the local water
hardness level. See Programming
Manual "Operation information -
Reactivation".
Reactivation display
After a certain number of cycles the
message REACTIVATION will appear in
the display to inform you that the water
softener is empty. Immediately after
the program has finished, reactivation
salt must be replenished.
If this cannot be done immediately, and
further cleaning cycles have been
carried out, the reactivation process will
need to be carried out twice in a row.
