Problem
The weld seam is
defective or not
properly sealed in one
or more places.
The  sensor is lit up
even though a drying
cycle has been carried
out. The drawer cannot
be used.
The  sensor lights up
yellow. The vacuum is
less than usual.
The  sensor lights up
red. A vacuuming
process cannot be
started.
Possible cause and remedy
The sealing bar and/or counterpressure bar are dirty
or there are liquid residues on the sealing bar.
 Clean and dry the sealing bar and/or
counterpressure bar.
The rubber on the counterpressure bar is not evenly
fitted.
 Flatten the rubber.
The edge of the bag is dirty (inside and out). For a
perfect weld seam the edge of the bag must be dry
and grease-free in the area of the seam.
 Fold the edges of the vacuum sealing bag
outwards for filling. This will give you a clean,
perfect weld seam.
The edge of the bag was not positioned smoothly
and without creases on the sealing bar.
 Position the bag smoothly and without creases
along the sealing bar.
The drying cycle failed to remove all of the moisture
from the oil circulation system in the vacuum pump.
The drawer is locked and cannot be used for 1 hour.
 Carry out another drying cycle after 1 hour (see
"Cleaning and care - Carrying out a drying cycle").
Ensure that the vacuum chamber is free of liquid
residues.
During vacuuming, moisture has got into the oil
circulation system in the vacuum pump. This can
result in a reduced level of vacuuming performance.
 Carry out a drying cycle (see "Cleaning and care -
Carrying out a drying cycle").
During vacuuming, moisture has got into the oil
circulation system in the vacuum pump. If the
 sensor lights up red, the drawer is locked for
further use.
 Carry out a drying cycle (see "Cleaning and care -
Carrying out a drying cycle").
