10 FAULTS AND REMEDIES
10.1 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.
Warning! The operations should be carried out by a qualified professional.

ANOMALY
POSSIBLE CAUSE
INTERVENTION
The compressor will
not start
- power failure
- check that there is voltage in the plug
- thermostat on the off position, or set to the mini-
mum
-
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
operating excessi-
vely 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 temperature
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
too much noise
coming from the
appliance, but it is
working normally
- the machine is not levelled
- level the appliance using the adjustable feet
- a few pipes are touching some parts inside the appliance,
thus causing it to vibrate
- adjust the position of the pipes, making sure they do not touch
any other parts
cold water comes
out slowly or not
at all
- 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 com
-
plete freezing of the ice compartment
- make the ice melt.
replace the temperature adjuster
The water is not
sufficiently hot.
- The HOTTER thermostat setting is too low
- Increase the value set in a phased manner to avoid creating
steam. Use the values recommended in paragraphs 6.3 and
6.4.
- The heating elements are full of scale.
- Follow the descaling procedure (rif.8.2)
- The safety thermostats have tripped.
- Reset the safety thermostats (ref. 8.3)
It generates steam
under pressure
at the point of
delivery
- The HOTTER thermostat setting is too high
- Use the values recommended in paragraphs 6.3 and 6.4.
