Miele PROFESSIONAL PG 8050I - Manual (Page 14)

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 cookware and in the
dishwasher.
Water with a hardness level higher than
4 gr/gal (4° d – German scale) needs to
be softened. This takes place
automatically in the integrated water
softener.
– The water softener requires
dishwasher reactivation salt.
– The dishwasher must be
programmed for the water hardness
in your area.
– Your local water authority can advise
you of the water hardness level in
your area.
Where the water hardness fluctuates
e.g. between 8 - 18 gr/gal (8 - 17 °d
German scale) always program the
dishwasher to the higher value (17°d in
this example).
If the water in your area is very soft
and consistently lower than 4 gr/gal
(4 °d) you do not need to add
dishwasher salt. The salt indicator,
however, will still come on, but
should be ignored.
Local water hardness:
gr/gal or °d
The dishwasher is programmed at
the factory for a water hardness level
of 20 gr/gal (19 °d).
If this setting corresponds with the
hardness of your water, continue with
"Rinse aid".
If your water is harder or softer, you will
need to program the water hardness
level using the buttons on the control
panel.
The programming can be canceled
at any time by pressing the "On/Off"
button. The procedure can then be
restarted.
Checking the programmed water
hardness level
^ Turn the dishwasher off with the
"On/Off" button.
^ Press and hold the "Extra drying"
and "Start / Stop" buttons in and turn
the dishwasher on with the "On/Off"
button.
^ Release the buttons.
The hardness level set will flash in the
display.
The digit sequence after the
a
indicates the hardness level set in °d.
^ Turn the dishwasher off with the
"On/Off" button.
