FAULTS AND REMEDIES
warning! The operations should be carried out by a qualified professional.
9.1
DIAGNOSIS AND OPERATING ANOMALIES
This section includes the typical anomalies that could occur.
Many of these problems are not caused by the cooler, but they could be brought about by the electricity supply or by an incorrect use of the water cooler.
In the ANOMALY column, the problems reported by the customer are listed.
In the POSSIBLE CAUSES column, the "probable reasons" behind the problem are listed.
In the INTERVENTION column, the corresponding corrective action is listed.
COOLING SYSTEM
ANOMALY
the compressor will
- power failure
not start
- temperature setting on probe is too high
- faulty thermostat
- the over-load protection of the compressor is faulty
- the starting relay is faulty
- the starting capacitor is faulty
- the compressor is faulty
the water is cold but
- little ventilation
the appliance is ope-
- the condenser is dirty or covered
rating excessively or
- the thermostat is on maximum cold position
non-stop
- the room temperature is higher than 32°C
the compressor
- gas leak from the cooling system
works continuously,
- the compressor is faulty
but the water is not
cold
COOLING SYSTEM
too much noise com-
- the machine is not levelled
ing from the appli-
- a few pipes are touching some parts inside the ap-
ance, but it is work-
pliance, thus causing it to vibrate
ing normally
cold water comes
- low pressure of the inlet water
out slowly or not
- faulty solenoid valve
at all
- clogged water filter
- the temperature adjuster is faulty and causes
complete freezing of the ice compartment
CARBONATING SYSTEM
the carbonated water
- the pressure of the gas in the co2 reducer is set
is not very fizzy or
to less than 3 bars
not at all
- co2 cylinder empty
- the temperature of the outlet water is high
- air bubbles inside the carbonator
only gas comes out of
- the level probes are dirty
the carbonated water
- the pump turns continuously
outlet
- the pump turns continuously, inlet water is pre-
sent
- the pump is blocked or the pump-motor is not
working
- the level controller is faulty
- the pump safety device has intervened (no water) - check that there is pressure in the network
continuous dripping
- dirty solenoid valve
from the outlets
the still water comes
- there is a shortage of inlet water
out carbonated
POSSIBLE CAUSE
INTERVENTION
- check that there is voltage in the plug
- set the temperature probe to a lower temperature
- replace the thermosta
t
- replace it
- replace it
- replace it
- replace it
- place the appliance away from the wall
- clean the condenser or free it of its obstacles
- adjust it
- it is normal that the appliance works at a continuously high room tempe-
rature
- contact a specialised technician (refrigerationist)
- replace the compressor
- level the appliance using the adjustable feet
- adjust the position of the pipes, making sure they do not touch any other
parts
- take steps to increase the pressure (autoclave)
- replace it
- replace it
- make the ice melt.
replace the temperature adjuster
- increase up to 3.5 – 4 bars
- replace it
- adjust the position of the thermostat to maximum
- clean out the carbonator
- control and replace
- no water is entering or the water filter is blocked
- the pipe fitting into the carbonator is obstructed. disassemble and clean
- check it and replace it
- control and replace
disconnect and reconnect the machine from the electrical network to reset it
- disassmeble the solenoid valve and clean it
- disassemble and clean or replace
