The appliance does not automatically switch
to the sealing procedure after vacuuming:
• A negative pressure sensor is installed in this
appliance. The appliance does not change to
the sealing procedure automatically if the
vacuum pressure in the bag cannot reach the
specified vacuum pressure.
Check the sealing strips and the foam seals
under the cover for soiling and correct posi-
tion. Wipe clean and smooth them again.
Try again.
• Make sure that the foam seals on the cover
and on the base around the vacuum chamber
do not break or distort. Take this out of the
tray, wash and dry it thoroughly. Or replace it
with a new foam seal (obtain this from your
nearest service centre).
• The vacuum bag may have a leak. For testing,
seal the bag with a little air, immerse it in
water and apply pressure. Bubbles are an
indication that there is a leak. Seal the bag
again or use another one.
• Leaks may be along the seal that are caused
by folds, crumbs, grease of liquids. Open the
bag again, wipe out the top end of the bag
and smooth it along the sealing strip before
re-sealing.
Air enters the bag again after sealing:
• Leaks may be along the seal that are caused
by folds, crumbs, grease of liquids. Open the
bag again, wipe out the top end of the bag
and smooth it along the sealing strip before
re-sealing.
• Natural gases may be released or result in
fermentation of food products (such as fruit
and vegetables). Open the bag and if you
believe that the food is beginning to deterio-
rate, and throw it away. Insufficient cooling
or fluctuating temperatures in the fridge may
lead to the food products deteriorating.
If the food product has not deteriorated, these
should be consumed immediately.
•
Check the bag for damage or a hole that may
allow the vacuum to escape.
Do not vacuum hard objects with sharp tips.
Pad sharp edges with paper towels in order to
avoid damage.
The bag melts:
• If the sealing strip or the sealing element
overheats and brings the bag to melt, the co-
ver may have to be raised to allow the sealing
strip of the heating element to cool down for
a few minutes.
A vacuum is not generated in the container:
• Make sure that the connecting hose is con-
nected tight with the appliance and container.
•
At the beginning of the vacuuming procedu-
re, press on the container lid OR on the hose
adapter in order to prevent the container seal
from leaking.
• Check if there is any damage. If yes, replace
the damaged parts with new ones.
• Check the function of the vacuuming appli-
ance.
• Make sure that the edge of the container is
clean enough. If all situations mentioned
above have been ruled out, please contact
the service centre specified.
