Regular descaling  

 CAUTION! 

In order to prolong the life of the unit and maintain a high level of coffee 
quality, the coffee machine should regularly be cleaned of deposits! 
Returns will not be accepted if the coffee machine has not been cleaned of 
deposits regularly - as written in the instructions for use.  
Such complaints are not subject to repair under warranty! 

 

o

  During use of the coffee machine, depending on the hardness of the local water supply 

internal parts of the unit can become covered in calcium deposits. In order to maintain 
the unit in the best possible condition and ensure the best possible results from each 
brewing cycle it is necessary to clean the unit of deposits from time to time. 

o

  Under conditions of heavy use the coffee machine must be cleansed of calcium 

deposits every two weeks, as well as cleansed of oils, stains from coffee, and other 
heavy residues. 

o

  For cleaning use commercially available coffee maker cleaning agents. 

o

  You should also the deposit removal process  the coffee machine when the brewing 

process starts taking longer, when the brewing sounds get louder or in case the 
coffee machine shuts off although there is still water in the tank (e.g. in case of very 
hard water). 

o

  For removal of calcium deposits we recommend „Bartscher Fast descaler for 

coffee machines“ a formula tried and tested by us: 

(Code-No.: 190065; packaged in 30 portions of 15 g/each). 

o

  Dissolve the calcium deposit removal formula (15g) in 1-2 litres of water. 

o

  Pour the solution containing the calcium deposit removal formula to the water tankfor 

the coffee machine. 

o

  Insert the filter basket by sliding it along the appropriate guides (without coffee).  

o

  Place the empty thermo jug on the bottom plate under the filter basket. 

o

  Turn the unit on as for normal use.  

o

  After several drops of the solution have flowed into the thermo jug, turn the coffee 

machine off. 

o

  Wait 5-6 minutes for the remainder of the solution to dissolve the deposits, then turn 

the unit on again. 

o

  After the entire solution has flowed through the machine, turn the coffee machine off 

and dispose of the solution. 

o

  After finishing the deposit removal process it is necessary to repeat the brewing 

process 2-3 times using only water, in accordance with the instructions contained in 
this insert and/or instructions for use. Water remaining in the coffee machine must 
then be removed with the help of the flow valve located on the rear wall (at the 
bottom) of the unit.  

o

  Rinse the thermo jug several times with warm water.
