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 coffee bed is not
flat enough.
Extend
pause 2 brewer (extraction)
to give
the coffee the time to get wet completely.
This mostly result in a flat coffee bed after the
vacuum process.
The coffee residue remains
too wet. Coffee residue
drops from both sides
when the brewer chamber
lifts.
The permanent filter is
dirty or worn.
Clean or replace the permanent filter.
The coffee residue is
not being vacuumed
long enough.
Execute brewer motor calibration program.
Extend
pause 3 brewer (vacuum)
time, this
increases the vacuum process time.
Check if vacuum is lost because the piston
moves down too far down.
Shorten
start 3 brewer
time if coffee still
remains too wet.
If the above-mentioned
problem is not resolved:
Check the brewer
chamber and cylinder
for fractures.
Replace the defective parts.
Check the cylinder
for wear and tear or
scratches.
Replace the defective parts.
Check the Teflon seal
for wear and tear.
Replace the defective parts.
