Testing water hardness
Cleaning of the steam system depends on both frequency of baking with steam injection and on the
hardness of the water used.
Soak the test paper strip (supplied with the appliance) in water for one (1) second. Wait one minute,
then note the number of stripes on the paper.
Setting the hardness level – number of coloured bars on the strip:
• 4 green stripes Hrd 1
• 1 red stripe Hrd 2
• 2 red stripes Hrd 3
• 3 red stripes Hrd 4
• 4 red stripes Hrd 5
