RESEARCH OF MALFUNCTIONS
NR ANOMALIES
CAUSES
SOLUTIONS
1
The machine does
not start.
1) lack of power supply;
2) lack of one phase.
1) verify that the voltage is 400V-50Hz
2) verify the connections of outlets and
plugs, the status of fuses and electric
panel protections of the machine and
of the building site distribution panels
2
The machine stops
and the green war-
ning light blinks
"Lack of water"
1) insufficient water
pressure;
2) clogging of the water
filter.
1a) verify whether the water pump had
been enabled;
1b) verify the grip status of the pump
fittings;
2) extract the water filter and clean it,
if necessary, replace it.
3
The gearmotor
does not start.
1) gearmotor under
stress;
2) tap of the spraying
nozzle closed;
3) nozzle of the spraying
nozzle clogged;
4) material scaling in the
mixing chamber;
5) power supply plug not
inser-ted.
1) remove the power supply plug, open
the mixing chamber and rotate the
rotor to the right using the proper "T"
wrench.
In case of blocked rotor, replace it;
2) open the tap of the spraying nozzle;
3) carefully clean the nozzle of the
spraying nozzle;
4) disassemble the rotor / stator
assembly and carefully clean the
mixing chamber or ice; re- assemble
the rotor / stator assembly;
5) insert the power supply plug.
4
The gearmotor
stops- thermal
protection tripping
1) mixture too hard;
2) use of a too long tube
compa-red to the
material used;
3) use of not suitable
mate-rials.
1) perform the reset of the thermal
switch tripping, (if
necessary, request the technical service
intervention) and re-start the machine
with more water;
2) reduce the length of the tube;
3) verify the product data sheets.
5
Th e c o m p r e s s
o r stops ther-mal
pro- tection
intervention
1) mechanical breaking
of the compressor;
2) intake filters blocked
3) cables or plug
damaged
1) ask for technical assistance;
2) replace the filters;
3) check the cable and the plug and if
necessary replace them;
6
Water level in the
mixing chamber is
increasing.
1) mixer blocked;
2) mixer not enabled;
3) excessive water flow
rate;
4) stator/rotor assembly
tear.
1a) verify that the mixer has been
started;
1b) verify the gearmotor power supply
cable;
1c) verify that the insertion of the
outlet in the electric plug of the
gearmotor;
1d) insert the power supply plug;
2) insert the mixer;
3) reduce the water flow arte indicated
on the flow meter acting on the adjust-
ment valve;
electric panel .
4) replace the assembly stator rotor.
7
The water pump
stops—thermal
protection tripping
1) Blocked pump
2) Damaged cables and
plug
1) Reset intervention thermal ask any
technical assistance interven-tion;
2)check the cable and plug and replace
any damaged parts
