Replacing the water filter
As coffee is largely made up of water, it is obvious that the water filter of a fully automatic coffee machine is a particularly important component for the flavour and quality of the coffee. Nevertheless, changing the water filter is often neglected due to ignorance. Limescale deposits in particular lead to a massive loss of flavour. It is advisable to change the filter after just a few months. Some machines indicate the need to change the filter. However, as a rule of thumb, you can remember that the water filter should be changed every two months or after 220 litres have been run through.
In most cases, the filter can be changed independently by following the steps below: Remove the water tank, take out the filter and fill the tank with about half a litre of water. Before inserting the new filter, immerse it in the tank at a slight angle until air bubbles can escape. Place the new filter back into the tank and reinsert the water tank into the machine.
