Problem Possible cause and solution
The weld seam is de-
fective or not properly
sealed in one or more
places.
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 counterpres-
sure 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 outward
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 sensor is lit up
even though a drying
cycle has been carried
out. The drawer cannot
be used.
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 1hour.
Carry out a further drying cycle after 1hour (see
“Cleaning and care – Completing a drying cycle”).
Make sure that the vacuum chamber is free from
liquid residues.
The sensor lights up
yellow. The vacuum is
lower than usual.
Moisture from the food vacuuming process has got
into the oil circulation system in the vacuum pump.
This can result in a reduced level of vacuuming per-
formance.
Carry out a drying cycle (see “Cleaning and care –
Completing a drying cycle”).
The sensor lights up
red. A vacuuming
process cannot be
started.
Moisture from the food vacuuming process 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 –
Completing a drying cycle”).
