COOLING SYSTEM

GB

ANOMALY

POSSIBLE CAUSE

INTERVENTION

Ithe compressor will 
not start

-  power failure

-  check that there is voltage in the plug

-  thermostat on the off position, or set to the mi-

nimum

-  adjust the thermostat position

-  faulty thermostat

-  replace the thermosta

t

-  the over-load protection of the compressor is faulty 

-  replace it

-  the starting relay is faulty

-  replace it

-  the starting capacitor is faulty

-  replace it

-  the compressor is faulty 

-  replace it

the water is cold but 
the appliance is ope-
rating excessively or 
non-stop

-  little ventilation

-  place the appliance away from the wall 

-  the condenser is dirty or covered

-  clean the condenser or free it of its obstacles

-  the thermostat is on maximum cold position

-  adjust it

-  the room temperature is higher than 32°C

-  it is normal that the appliance works at a continuously high room tempe-

rature

the compressor 
works continuously, 
but the water is not 
cold

-  gas leak from the cooling system

-  contact a specialised technician (refrigerationist)

-  the compressor is faulty

-  replace the compressor

COOLING SYSTEM

too much noise com-
ing  from  the  appli-
ance, but it is work-
ing normally

-  the machine is not levelled 

-  level the appliance using the adjustable feet

 -  a few pipes are touching some parts inside the ap-

pliance, thus causing it to vibrate

-  adjust the position of the pipes, making sure they do not touch any other 

parts

l’acqua fredda esce 
piano o non esce

-  low pressure of the inlet water

-  take steps to increase the pressure (autoclave)

-  faulty solenoid valve

-  replace it

-  clogged water filter 

-  replace it

-  the  temperature  adjuster  is  faulty  and  causes 

complete freezing of the ice compartment

-  make the ice melt.
  replace the temperature adjuster

CARBONATING SYSTEM

the  carbonated  wa-
ter  is  not  very  fizzy 
or not at all

-  the pressure of the gas in the co2 reducer is set 

to less than 3 bars

-  increase up to 3.5 – 4 bars

-  co2 cylinder empty

-  replace it

-  the temperature of the outlet water is high

-  adjust the position of the thermostat to maximum

-  air bubbles inside the carbonator

-  clean out the carbonator

only gas comes out 
of  the  carbonated 
water outlet

-  the level probes are dirty

-  control and replace

-  the pump turns continuously

-  no water is entering or the water filter is blocked

-  the pump turns continuously, inlet water is pre-

sent

-  the pipe fitting into the carbonator is obstructed. disassemble and cle

-

an

-  the pump is blocked or the pump-motor is not 

working

-  check it and replace it

-  the level controller is faulty

-  control and replace

-  the pump safety device has intervened (no wa-

ter)

-  check that there is pressure in the network
  disconnect and reconnect the machine from the electrical network to reset it

continuous dripping 
from the outlets

-  dirty solenoid valve

-  disassmeble the solenoid valve and clean it

the still water comes 
out carbonated

-  there is a shortage of inlet water 

-  disassemble and clean or replace
