Water Hardness - Miele PG 8080U Operating Instructions Manual

Water hardness

Your commercial dishwasher is fitted
with a water softener. The dishwasher
must be programmed for the water
hardness in your area.
– The commercial dishwasher must be
programmed to match exactly the
hardness of your water.
– Your local water supplier can tell you
the water hardness level in your area.
– Where the water hardness fluctuates
e.g. between 18 - 26 gr/gal (17 -
25 °d - German scale), always
program the commercial dishwasher
to the higher value (26 gr/gal or 25 °d
in this example).
 Select the hardness of your water
and press the centre button to
confirm.
A check  will appear beside the water
hardness which has been set.
