Water hardness
The display changes to the water hard‐
ness setting.
– The dishwasher must be program‐
med for the water hardness in your
area.
– Your local water supplier can tell you
the water hardness level in your area.
– Where the water hardness fluctuates
e.g. between 10 - 16 gr/gal (10 - 15
°d), always program the dishwasher
to the higher value (16 gr/gal or 15 °d
in this example).
It is useful to know your water hardness
so that you can provide the service
technician with this information in the
event of any service calls.
