13. Maintenance and cleaning

Neither the coffee machine nor the accessories are dishwasher-safe!
Clean the product after use. Do not immerse the product including the mains cable in water or
other liquids!
Disconnect the product from the mains before cleaning and wait for the product to fully cool
down to room temperature. Please note that the keeping-warm plate cools down slowly.
• Never use aggressive cleaning agents (except for suitable descaling agents), rubbing alcohol or
chemical solutions, as those could damage the housing or even affect the functioning of the device. Do
not use hard or scratching brushes, sponges, or similar.
• Despite occasional cleaning, the product is maintenance-free. There are no components located inside
the product you need to maintain. Never dismantle the product.
• Open the lid of the water tank and remove the permanent filter and filter holder. Empty the permanent
filter and rinse it under running water.
• Rinse the glass jar with lid, filter holder and measuring cup under warm water.
• Clean the exterior surface of the coffee machine and the keeping-warm plate with a clean, soft and
slightly damp cloth. Clean the mains cable with a dry cloth.
• After having cleaned and dried all parts, reinstall the filter holder and permanent filter, close the lid of the
water tank, and then place the glass jar with closed lid on the keeping-warm plate.

14. Descaling

Descale the water tank from time to time. The periods in-between depend on the hardness of the water
and the frequency of use.
• Use a commercially available liquid descaling agent for descaling and dose according to manufacturer
instructions. Never use vinegar.
• Fill the water tank with descaling solution and leave it according to manufacturer instruction.
• Turn on the product and start brewing with the solution of water and descaling agent.
• Then dispose of the descaling solution in the glass jar.
• After descaling, brew water for three or four times in order to remove any residue of the descaling
solution.
• The descaling solution and its residue are not suitable for consumption. Pour the solution and the boiled
water away.
• Then clean the glass jar, permanent filter and filter holder as described in chapter "13. Maintenance and
cleaning".
