Setting the water hardness
level
The steam oven is set at the factory to
water hardness setting IV (
4
) .
If your water hardness level differs from
this you will need to re-programme the
appliance.
You can use the test strip supplied to
check the water hardness level, or your
local water supplier will advise you on
the water hardness of your area.
The water hardness is shown as
settings I to IV equivalent to the
German scale 1 to>21 °dH (0.2 - 3.8
mmol/l).
