8 Fault Finding
In this chapter, you will find defects that
may appear, as well as the corrective
actions you may carry out to put the
appliance back in service. Other fault
codes MUST be solved by a competent
person only.
Defect
Possible cause
Solution
The appliance
stops working
Electrical circuit
interrupted
Check that there is no power cut and that the appliance
is correctly connected. When electrical power comes
back on, the appliance automatically comes back into
service. If the fault persists, contact your Installation/
Servicing company or Glow-worm Service.
Noise (hissing,
banging,
buzzing)
When the heating has stopped, a whistling or bubbling noise may be heard.
This noise is generated when the refrigerant flows through the unit.
When the unit is started or stopped, a cracking noise may be heard. This noise
is generated as a result of the expanding or contracting of the housing caused
by changes in temperature of the different materials and is quite normal.
When the system is in operation a humming may be heard. This noise is
generated when the unit defrosts in heating mode and is caused by the
reversal of the refrigerant flow.
Emits mist
In winter and during the defrosting period, a cloud of mist may be produced in
the outdoor unit; this is due to the heat melting the ice which has formed.

• If after carrying out this basic advice
and your appliance still does not work,

competent person.
