It is difficult to
create a
vacuum in the
containers.
1. The gaskets between the
various components are dirty,
damaged or positioned
incorrectly.
2. Faulty pump.
3. Intake filter clogged.
1. Examine the gaskets, clean if
necessary and lubricate them with
Vaseline. Clean mixing unit components
thoroughly (see paragraph 8.1.1).
2. Contact an Authorised Service Centre.
3. Change the filter (see section 8.1.2).
After turning the
main switch to
ON the machine
does not work.
1. Plug is not connected to
the mains socket.
Power lead is damaged.
2. Fuse blown.
1. Connect the plug to the mains socket
properly.
2. Change the fuse, using one of identical
characteristics. Contact an Authorised
Servicing Centre only.
The pump does
not start.
1. Sensor on board and/or
magnet on cup lid faulty.
1. Contact an Authorised Service Centre.
- Error n°1: if, 2 minutes after positioning the cup, the pressure still hasn’t dropped below the
threshold (= 50) a warning appears and the pump is switched off. In this case it is necessary to
carry out an inspection and trace the problem (e.g. the cup may be positioned incorrectly, the
vacuum sensor tube disconnected, the pump disconnected…) before restarting the cycle.
- Error n°2: if, during the cycle, the cup is no longer detected, a warning appears and the
outputs are deactivated. In this case it is necessary to carry out an inspection and trace the
problem and then restart the cycle. This error may occur if the vacuum sensor is faulty:
measured pressure may be below the threshold (otherwise error 3 would be shown) but the cup
detaches. In this case the motor is stopped to prevent injury to the operator.
- Error n°3: if, during the cycle, the vacuum is insufficient (i.e. pressure rises above the
threshold = 50) a warning appears and the motor is switched off. this case it is necessary to
carry out an inspection and trace the problem (e.g. cup detached, vacuum sensor tube
disconnected, pump disconnected…) before restarting the cycle.
-
Error n°4:
when the
elite mix
control unit is switched on the pump is activated for 5 seconds to
check whether the filter is dirty (i.e. without the cup): if the pressure drops below a certain level this
means that the filter is clogged and an error warning appears. In this case the filter must be
replaced.
