Adjusting the brewer
1.7.1.1
Clamping force
The clamping force of the brewer chamber must be set in order to prevent too much water from leaking
through the filter paper. You can see if water is leaking by checking the filter paper. If the filter paper is wet
for more than one centimetre all round after a cup of coffee has been made, too much water is leaking. The
clamping force may not be set too high because doing so will cause excessive wear or the brewer motor to
get jammed.

Adjusting the clamping force
Fig. 20 Adjusting the brewer chamber
D Place a piece of filter paper between the brewer and the brewer chamber.
D Rotate the brewer housing upward to the highest position.
The brewer chamber is all the way down and pressing on the filter paper.
D Turn the adjustment bolt (1) behind the brewer chamber such that the filter paper cannot be pulled out
from between the brewer chamber and the brewer.
D Tighten the adjustment bolt by turning it half a turn or a full turn.
D Put the brewer back in the machine.
D Insert the filter paper as described in the instructions.
D Make sure it works by making a cup of coffee (use the service key).
D Fasten the adjustment bolt by turning it a quarter of a turn if too much water leaks along the filter paper.
D Loosen the adjustment bolt by turning it a quarter of a turn if the brewer housing does not move evenly in
the lowest position (when the brewer chamber rises).
1.7.1.3
Paper transport
The filter paper transport should be set in such a way that the distance between the cakes of coffee residue
is large enough for the next cycle to take place on a piece of filter paper that is completely clean.
To prevent excessive paper use and replacing the roll too often, make sure the distance between the cakes
of coffee residue is not too large.
The distance between the cakes of coffee residue should be between 5 and 10 mm.
