Setting the water hardness

For trouble-free operation of the coffee

machine, and to ensure that the

descaling reminder appears in the

display at the appropriate time, it is

important to set the water hardness

level. The water hardness level

indicates how much calcium is

dissolved in the water. The higher the

calcium content, the harder the water,

and the harder the water, the more

often the machine will need to be

descaled.

The machine measures the amount of

water which has been taken in

(including the amount required for

producing steam). The amount of water

which the machine can use before it

needs to be descaled will depend on

the water hardness level set. Less

water will be used in hard water areas

than in soft water areas.

Your local water authority will be able to

tell you the hardness of water in your

area. Alternatively, you can measure

the hardness yourself using the

enclosed test strip:

^

Dip the strip in your drinking water for

approximately a second, then shake

off any excess water. The result will

be evident after about a minute.

If the water is harder than

40°d/7.0 mmol/l, limescale will build

up more rapidy than with soft water.

Descaling will need to be carried out

more regularly than stated to

prevent limescale damage to the

machine.

The machine has four programmable

levels:

–

Soft:

Local water hardness level 1

0-3°d (0-0.6 mmol/l)

Water through-flow: approx. 100 l

Steam through-flow: approx. 120

min.

– Medium:

Local water hardness level 1

4-7°d (0.7-1.3 mmol/l)

Water through-flow: approx. 80 l

Steam through-flow: approx. 90 min.

– Hard:

Local water hardness level 2

7-14°d (1.3-2.5 mmol/l)

Water through-flow: approx. 60 l

Steam through-flow: approx. 60 min.

–

Very hard:

Local water hardness levels 3-4

14-21°d (2.5-3.8 mmol/l) or more

Water through-flow: approx. 40 l

Steam through-flow: approx. 30 min.

^

Select "Settings F" from the Main

menu, and then touch the OK sensor.

^

Use the arrow sensors to highlight

"Water hardness" and then touch the

OK sensor.
