FAULT‐FINDING GUIDE
WORKING FAULTS POSSIBLE CAUSES SOLUTION
All the lights on the
command panel blink. Overheating; circuit board
damage Turn the machine off and wait around 15
minutes for it to cool down and for the thermal
protection to be automatically restored.
If, on switching the machine back on, the
same problem occurs, call a service
technician to replace the power board.
The STOP button light
blinks accompanied by an
intermittent acoustic
signal. Insufficient vacuum in the
chamber (the vacuum
chamber does not signal
the minimum vacuum
having been reached to
the power board).  Lid not pressed down at the start of
the cycle.
 Lid of the preserving jar badly
positioned
 Lid seal worn or badly positioned.
 The intervention of a technician is
required to check the air circuit, the sensor
board and the vacuum pump.
 The intervention of a technician is
required to check the correct electro valve
opening.
 Vacuum pump in thermal protection
state: switch the device off and wait around 15
minutes.
When switching on, all the
lights on the command panel
blink for 3 seconds and the
acoustic signal is audible
(long Beep). Oil change warning due to
having reached 2500
working cycles. Intervention of a technician required for
pump oil substitution.
The cycle starts up
(blinking buttons) but the
pump does not start up. Pump thermal protection
intervention due to
overheating. Switch the device off and wait around 15
minutes before switching the power back on.
The machine will not
switch on. Energy shortage. Check the electrical connection.
Low vacuum level in the
bag 1) Irregular bag
soldering
2) Irregular
bag
soldering line
3) Dirty or perforated
bag.
4) Insufficient soldering.
5) Bag size not suitable
for the size of the
product.
6) Insufficient pump
performance.
1) Position the bag correctly.
2) Check the state of the Teflon cover.
Technical intervention to substitute the Teflon
and check the soldering resistance.
3)
Change the Bag.
4) Choose a bag where the volume of
the product is not more than 2/3 of the
volume.
5)
Intervention of a technician required
to check the pump
The device does not solder
the bags. 1) Dirty contacts.
2) Soldering resistance
bar broken.
3) Power shortage.
4) 3-way electro valve
blocked or dirty.
1) Remove the soldering bar from the
two screws and clean the two bar contact
holes with a small brush.
2)
Intervention of a technician required
for its substitution.
3)
Intervention of a technician required
to check the leads and the power board.
4)
Intervention of a technician required
for its substitution.
