• You can set the off time in Service mode 1 (see section Setting Auto OFF).
• If no beverage has been prepared since switching on or if the water tank is empty, no rinsing takes place.

Filling coffee beans into the bean container

Roasted coffee beans lose their aroma. Only fill the bean container with as many coffee beans as you will consume over the next 3 to 4 days.

ATTENTION
The use of unsuitable types of coffee can lead to clogging of the grinder.

• Do not use freeze-dried or caramelised coffee beans.
• Do not use any coffee powder or instant products.

When changing the type of beans, remains of the old type of beans can still be in the grinder.
Even if the bean container runs empty and a new type of bean is filled in, there are still remains of the old type of bean in the grinder. For this reason, the first two coffees dispensed can contain remains of the old type of bean.

The flashing Coffee bean display requests you to refill coffee beans.

Fig. 5: Opening the lid of the bean container

1. Open the lid of the bean container. (3).
2. Fill coffee beans into the bean container.

Care and maintenance

Regular care and maintenance of the appliance ensure the consistent high quality of your beverages.

General cleaning

Clean the appliance regularly. Immediately remove external soiling caused by coffee.

ATTENTION
The use of unsuitable cleaning agents may lead to scratched surfaces.

• Do not use any abrasive cloths, sponges or cleaning agents.

Requirement: The appliance is switched off.

• Clean the outside of the appliance with a soft, damp cloth and normal washing-up liquid.
• Rinse off the drip tray, the coffee container and the cup plate. Use a soft, damp cloth and normal washing up liquid for this. The coffee container is dishwasher-safe.
• Clean the bean container with a soft, dry cloth.

If the descaling programme has been interrupted, e.g. by unintentionally switching the appliance off, you must switch the appliance on again and follow the instructions from step 9. The appliance is then ready for operation, even if it has not been completely descaled. For complete descaling, you must run the descaling programme from the beginning.

Using a water filter

The use of a water filter extends the service life of the appliance and the appliance has to be descaled less frequently. The water filter filters calcium and other pollutants out of the water.

Only use Melitta® Pro Aqua filter cartridges for fully automatic coffee machines. Observe the processing instructions on the packaging of the water filter.

When using and regularly replacing the Melitta® Pro Aqua filter cartridge, the appliance only needs to be descaled once a year.
This information is based on an average of 6 coffee beverages with 120 ml per day and 6 filter changes per year.

Fig. 15: Screwing/Unscrewing the water filter

The water filter (21) is screwed into and unscrewed from the thread (22) on the base of the water tank (1).

The water filter should not be left standing dry for a long period of time. When it is not used for a long time, we recommend storing the water filter in a vessel filled with tap water in the refrigerator.
