Cleaning And Maintenance; Scaling Indicator; Setting The Water Hardness - WMF LINEO Mode D'emploi

Cleaning and maintenance

Cleaning
Unplug the mains plug and allow the appliance to cool down.
Do not immerse the device in water, but rather clean it on the outside with a damp
cloth and a little washing-up fluid.
Do not use any sharp and abrasive cleaning agents.
The filter, teapot and vacuum jug can be cleaned under running water.

Scaling indicator

Scale deposits lead to an extended brewing time and a lower quality of your coffee.
Limescale deposits also lead to losses of energy and impair the service life of the
device.
The automatic scaling indicator determines the time for the next descaling.
Depending on the coffee consumption and set water hardness, you will be prompted
to descale already after 4 to 6 weeks via the flashing CALC during the brewing
process.

Setting the water hardness

Your appliance has an automatic scaling indicator. To protect against too much lime
scale, the appliance is pre-configured ex-works for very hard water. Ask your local
waterworks or local authorities about the water hardness of your tap water. Change
the setting when the water hardness is less than 21°dH. You will not be asked to
descale as often as before.
To do so, hold the Set button down for about 7 seconds until Set CALC appears in
the display. The display CALC and the current set degree of hardness, e.g. H4 will
flash alternately. As long as the water hardness in the display is flashing, this can be
changed to water hardness 1, 2, 3 or 4 by pressing the
Confirm the setting by pressing the Set button.
Hardness range Hardness
1 soft 0 - 7° dH
2 medium >7- 14° dH
3 hard >14 - 21° dH
4 very hard >21° dH
1° dH corresponds to approximately 0.18 mmol/l Ca and Mg ions
