Descaling
After a period of use, limescale will build up in the appliance
(depending on the hardness of the mains water). You should remove
this limescale at regular intervals to guarantee the function of the
appliance. Limescale can cause performance to deteriorate
considerably.
Caution! Do not use commercially-available descalers, pure acetic
acid or vinegar essence.
1. Pour 50 ml of white vinegar and 50 ml of boiling water into the
appliance.
2. Leave it to take effect for 30 minutes.
Caution! Longer periods will not improve descaling but may
damage the appliance.
3. After this time, empty the appliance.
4. Rinse out twice with clean water.
5. Wipe dry the appliance.
