Tensile force too low ( g. 5) Tensile force correct ( g. 6) Tensile force too high ( g. 7)
If the wiper moves over the
upper side of the cylinder it
makes no
contact with the permanent
 lter, so that coffee residue is
left on the  lter. The wiper does
not bend at all.
If the brewer unit is adjusted in
this way it can leak. If leakage
is severe
this can even result in a
vacuum loss, which means
that the coffee residue remains
too wet (particularly for larger
dispensing volumes).
If the brewer is adjusted
correctly, the wiper moves
carefully over the upper side
of the cylinder and pushes
the coffee residue off of the
permanent  lter. The wiper
bends slightly.
When the wiper moves to
the right the coffee residue is
transported to the waste bin.
The coffee residue drops from
the right side of the brewer
straight into the waste bin.
If the brewer is adjusted too
high, the wiper will stretch
and become clearly warped.
Glancing along the long side of
the wiper will show a warped
effect in the rubber.
The brewer is under extreme
pressure and the sound of the
brewer motor audibly changes
as a sign of the severe load.
This may even damage the
wiper!
During the complete brewer
cycle, ball bearings from the
wiper arms and the tension
member are under severe
pressure, resulting in bending.
The ball bearings may then
break away, cracking the plastic
brewer housing.
Signs that the tensile force is too high (fi g. 7):
The wiper is severely bent when it slides across the upper side of the brewer cylinder and •
permanent  lter.
It appears as if the wiper arm is  attened between the brewer unit and the upper side of the •
brewer cylinder.
The brewer motor sounds as though it is running under extreme pressure.•
The wiper pushes against the coffee residue when moving to the left.•
Accumulation of coffee residue round the waste bin.•

1.8.3 Troubleshooting
Problem Probable cause Action
The wiper pushes against the
coffee residue when moving to
the left.
The brewer unit does not rise
far enough.
The brewer unit is hindered
during the upward movement.
Check if the brewer unit is able
to move upwards freely.
The brewer unit tensile force is
too high.
Remove one adjustment shim
to reduce the tensile force.
The coffee residue remains
too wet.
Never increase the tensile force
under if the brewer unit tensile
force is set correctly.
There is inadequate suction in
the coffee residue.
Increase the pause 3 time (see
section 1.6)
The water temperature is too
high.
Lower the water temperature.
The permanent  lter is dirty or
worn.
Clean or replace the permanent
 lter.
If the above-mentioned problem
is not resolved:
Check the brewer unit and
cylinders for fractures.
Replace the defective parts.
Check the cylinder for wear
and tear or scratches.
Replace the defective parts.
Check the Te on coating for
wear and tear.
Replace the defective parts.
