9 Fault Finding
In this section fault codes that are
displayed, which CAN be carried out by
the USER to restore appliance operation
(Corrective action: ...). Other fault codes
MUST be solved by a competent person
only.
iLike all condensing boilers
it will produce a plume of
condensation from the ue
terminal in cool weather.
This is due to the high
eciency and hence low ue
gas temperature of the boiler.
It is normal and not a fault
indication.
• If after carrying out this basic advice and
your appliance still does not work, leave
it turned o and contact your competent
person.
Fault code Possible causes 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.
Fault
Press on the "reset" button. Wait for 5 seconds. If the fault
persists and the symbol
xx
appears, contact your
Installation/Servicing company or Glow-worm Service.
Lack of water in the
installation
(< 0.5 bars)
Open the lling tap located under the appliance until
you obtain a pressure of between 0.8 and 1.2 bars on
the indicator, refer to diagram overleaf. If relling needs
to be carried out too often, there may be a leak in your
installation. In this case, contact your Installation/Servicing
company or Glow-worm Service, to have your system
checked.
Excess water in the
installation
With central heating o, open the vent (bleed screw) on a
radiator to allow water to escape and reduce the pressure
in the heating circuit, or contact your Installation/Servicing
company or Glow-worm Service.

10 Appliance safety devices
10.1 Boiler Shutdown
The boiler software is designed to
recognise the potential for an overheat
lockout and will shutdown before this
happens.
• To restart the boiler, press the reset
button, see chapter «Appliance use ▸
Overview».
If the boiler fails to resume normal
operation and all external controls are
calling for heat, then call your Installation/
Servicing company or Glow-worm service.
10.2 Protecting against frost
Appliance Protecion
In case of the risk of frost:
• Make sure that the electrical and gas
supply to the appliance is turned on.
• For an absence of several days, select
the «frost protection» mode. In this
mode, only the water pressure in the
heating circuit is visible.
or
• Set the «holiday» mode in the external
control.
The frost-protection system starts the
appliance’s pump when the temperature
in the heating circuit goes below 12°C. The
pump stops when the temperature of the
water in the heating circuit reaches 15°C.
If the temperature in the heating circuit
goes below 7°C, the burner is lit until the
temperature reaches 35°C.
If the boiler is in «Domestic Hot Water»
mode only, the frost-protection system is
also active.
System Protection
The boiler alone cannot ensure that the
installation is protected against frost.
NOTE: Any other exposed areas of the
system should be protected by a separate
frost thermostat.
In case of prolonged absence, where power
to the dwelling and the boiler is switched
o, contact your Installation/Servicing
company or Glow-worm Service to have the
installation drained or to have the heating
circuit protected by adding an anti-freeze
specially designed for heating systems.
bCAUTION: Your domestic water
circuit (hot and cold) is not
protected by the boiler.
10.3 Condensate Drain Blockage
As a safety feature the boiler will stop
working if the condensate drain becomes
blocked. During freezing conditions this
may be due to the forming of ice in the
condense drain external to the house.
• Release an ice blockage by the use of
warm cloths on the pipe.
The boiler should then restart.
• Contact your Installation/Servicing
company or Glow-worm service if the
fault persists.
10.4 Safety Discharge Valve
The safety discharge valve and discharge
pipe is tted to the boiler.
• If there is any discharge from the pipe,
switch o the boiler electrical supply,
then call your Installation/Servicing
company or Glow-worm service.

12 Tips for saving energy
Your installer will be able to give energy
saving advice about your system and its
controls.
For energy saving advice you can contact
the Energy Savings Trust for advice or
visit www.energysaving trust.org.uk who

energy.
Regular servicing of your boiler will help
maintain its eciency - servicing once a
year is recommended.
Turn your thermostat down. Reducing your
room temperature by 1°C could cut your
heating bills by up to 10 percent. Set your
heating and hot water at the time controller
to come on only when required rather than
all the time.
