Cleaning And Care - WMF Lumero Instrucciones De Uso

To open the jug turn the lid slightly counter-clockwise. After closing the lid, ensure that the pour
button lines up with the jug handle.
The double-walled Cromargan® container is absolutely break-proof. Nevertheless, it should be pro-
tected against mechanical stresses.
Rinse the jug regularly. If iron particles from water accumulate on the Cromargan® surface, they can
create pitting at those points. These deposits must therefore be removed immediately with a stainless
steel cleanser. Do not clean in the dishwasher or in rinsing water.
Note: Stubborn deposits can be removed using soda, dishwasher granules or denture cleansing tablets.
Specific information about the light ring on the base of appliance
The light only serves as an information display and informs about the current status of the product.
▪ When the machine is ON, the base shines brightly.
▪ When the machine is OFF the base does not shine.

Activate/deactivate LED light ring
The LED light ring on your filter coffee machine is set to full luminosity by default and it lights up
during the brewing process and when keeping the coffee warm. To change the setting of the LED light
ring on your filter coffee machine, during standby mode press + and - simultaneously for at least
three seconds. You have three options to choose from when you press the + and - buttons. Setting 0
means that the LED light ring is switched off. If you choose setting 1, the LED light ring lights up at
50% luminosity. If you choose setting 2, the LED light ring lights up at full luminosity (same as default
setting). Press the ON/OFF symbol to confirm your selection.

Cleaning and care

Cleaning
Pull out the mains plug and allow the appliance to cool down.
Do not immerse the appliance in water. Outer surfaces can be cleaned using a damp cloth and a little
washing-up liquid.
Do not use harsh or abrasive cleaning agents.
The filter, glass jug and thermal jug can be cleaned under running water.
Scale indicator
Limescale deposits lead to longer brewing times and lower the quality of your coffee. They also lead to
energy losses and impair the service life of the appliance.
The automatic scaling indicator determines the time for the next descaling cycle. Depending on the
level of coffee consumption and water hardness, after 4 to 6 weeks the descaling symbol
during the brewing process, prompting you to descale the appliance.
Setting the water hardness
Note: The setting for individual water hardness is not necessary as the appliance detects the limescale
automatically.

Descaling - Anti-limescale program
To ensure an optimal descaling please let the device cool down to room temperature before starting
the descaling program. Descale your appliance regularly using a high-quality and suitable commercial
descaling agent. In doing so, refer to the manufacturer's information, especially with regard to the
subsequent mandatory cleaning step using clear water. Suitable descaling agents contain inhibitors
that protect appliances against damage to seals and surfaces, do not cause any deposits and are also
of neutral taste.
You must not use any agents for descaling that are unsuitable for the respective appliance (such as
pure vinegar or citric acid-based products). Our warranty does not cover damage caused by using
unsuitable descaling agents or failure to comply with the descaling instructions. Please keep descal-
ing agents out of the reach of children and make sure that you do not inhale any of the steam that is
emitted during descaling.
▪ Insert the paper filter and place the jug in the machine. Larger limescale residues may accumulate
in the paper filter, thus preventing the outlet valve from clogging.
▪ Add the quantity of descaling agent to the water tank as per the manufacturer's instructions, and
top up with tap water to the 10-cup mark (version with glass jug) or to the 8-cup mark (version
with thermal jug).
▪ To start the descaling, press the

▪ Note that the descaling process takes longer than the normal brewing process and may last quite a
while. Wait until the water has run completely through and the coffee machine switches off.
Important: Then to rinse, fill the tank to the 10-cup mark (version with glass jug) or to the 8-cup
mark (version with thermal jug) with fresh tap water and allow this to run through the machine.
