Use a citric acid solution (6g pure citric acid powder dissolved per 1 litre of water) as a descaling solution.
Descaling the filter
1. Fill a container with descaling solution.
2. Place the filter holder
8
including water level sensor
6
and filter
5
in the descaling solution so that
all parts are covered.
3. Leave for one hour. Then rinse everything thoroughly under running water. Never squeeze out the filter
5
as this may deform it.
4. Repeat this procedure if necessary.
