WARNING!
During the calcium deposit removal process you must not leave the coffee machine
unattended! It is necessary to wear protective gloves and goggles while performing
the calcium deposit removal process!
Cleaning the thermo jug
Hard water may leave white, mineral residues inside the jug. The coffee itself normally
discolours these residues and leaves brown marks. In order to remove these residues
follow the steps below:
1. Take a half-and-half solution of water and vinegar.
2. Leave this solution in the thermo jug for about 20 minutes and pour it out afterwards.
3. Rinse the thermo jug thoroughly and wipe it dry using a dry, soft cloth. Do not use
any kind of abrasive agents as this could cause scratches which could again result in
cracks.
CAUTION!
The thermo jug is not suitable for washing in a dishwasher!
