de-scaling
Regularly de-scale your coffee machine. The de-scaling interval depends on the hardness of the mains water and the coffee
machine's frequency of use. We recommend de-scaling the coffee machine after using one box of filter bags (approx.
40 brews). Due to scaling, the heating element can become obstructed. This causes overheating, as a result of which the coffee
machine is switched off automatically as a safety precaution and will no longer function. The machine will have to be repaired. You can
de-scale the coffee machine with a special de-scaling agent for coffee machines or with kitchen grade vinegar.
If you use a special de-scaling agent for coffee machines, you must observe the instructions on the packaging of this agent.
When using kitchen grade vinegar, proceed as follows:
1. Switch off the machine by pressing the on/off key. Remove the plug from the wall socket and remove all separate components
(glass jug, filter holder and permanent coffee filter).
2. To remove any remaining water, hold the machine upside down above the sink.
3. Fill half the water reservoir with cold kitchen grade vinegar and fill up with clean, cold water. Place the glass jug on the hot plate and
place the filter holder back on the machine with an empty filter bag.
4. Switch on the machine.
5. Allow half the kitchen grade vinegar with added water to flow through and then switch off the machine. Wait approximately 15
minutes and then switch the machine back on. As a result the scale will be softened and removed.
6. After de-scaling, allow at least 3 water reservoirs of cold, clean water to flow through the machine to remove all de-scaling liquid
and vinegar residues and prevent a foreign taste in the coffee.
Caution! If the coffee machine has not been used for some time, e.g. due to vacation, it is recommended to remove and clean all
separate components. Then place the separate cleaned components back and run the coffee machine once with clean water. In this
way you will prevent a possible foreign taste.
