Cleaning the thermo jug
Hard water may leave white, mineral deposits inside the thermo jug. Coffee usually
colour the deposits and leave the brownish deposit. To remove these deposits,
follow the below indications:
– prepare a solution of hot water and descaling agent (art. No. 190065);
– leave the solution in the jug for 20 minutes;
– pour the solution out;
– rinse the thermo jug thoroughly several times;
– wipe the exterior of the thermo jug with a soft cloth;
– leave the thermo jug open to dry completely.

Descaling
NOTE!
To reduce limescale deposits, it is recommended to use filtered water!
CAUTION!
Injury hazard!
Use safety gloves and goggles during descaling!
Depending on the water hardness level in the place of usage, limescale may be
deposited inside of the appliance's elements during the operation of the coffee
machine. In order to maintain the appliance in the best possible condition, and to be
certain that every brewing process yields the best results, the appliance should be
descaled regularly.
If used extensively, in order to remove oils, coffee stains and stubborn deposits the
appliance must be thoroughly cleaned and descaled every
two weeks
.
1. For thorough cleaning, use commercial agents for cleaning coffee machines
available on the market. Follow the manufacturer’s instructions.
2. The descaling process, as described below, should be performed also when the
preparation of coffee takes longer than usually, the sounds of brewing start to be
more distinct or the coffee machine switches itself off, although there is still
water in the tank (e.g. in the case of very hard water).
3. For descaling the appliance we recommend the tried and proven agent:
Descaling agent Bartscher B15-30 (art. no. 190065).
