4.6.4 Reinforced
brewing
unit
New, reinforced brewing units will be used from production date
FD8307.
Changes to components result in a higher pressure resistance in the
complete brewing unit as well as improved functional safety of the
entire machine.
Externally the new, reinforced brewing units can be identified by the
longer discharge chute on the brewing chamber.
(A)
Short discharge chute
= previous brewing unit
(B)
Long discharge chute
= new, reinforced brewing unit
4.6.4.1 Stripping-off
clip
To improve functional safety, a stripping-off clip
(B)
was fitted to the
brewing unit
(A)
.
This stripping-off clip is attached to the discharge chute on the
brewing chamber and moves closely past the brewing head
(C)
during
each brewing cycle. Coffee dregs which stick to the brewing head are
therefore removed mechanically.
Faults in the brewing cycle and during initialisation of the brewing unit
due to overdosage are therefore avoided.
Note:
The control lever is a component of the brewing unit and is not
available separately. All current replacement brewing units feature this
new lever.
