Setting the water hardness

The steam oven is set at the factory to water hardness setting

IV (Very hard 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 be able to

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).
