(ensure programmer is set to manual):
Symptom Fault
HLO on switching On mains Component fault on main PCB, incorrect wiring
HLO on turning On oven/grill Fault on control board / potentiometer,
incorrect wiring, open circuit solenoid.
Oven start up, burner lights and Short circuit thermistor assembly.
immediately goes out, ready light on Note: at room temperature, thermistor
resistance is approximately 100 kΩ.
Oven fails to ignite (check that 1. Incorrectly positioned or open circuit spark
electrode sparks correctly) electrode (note both grill and oven
electrodes must be connected).
2. Faulty solenoid valve.
3. Gas not at appliance.
4. Blocked injector jet.
Oven goes out before set 1. Incorrectly adjusted spark electrode (low
temperature is reached flame current).
2. Low gas pressure.
3. Incorrectly positioned potentiometer or
indicator disc.
4. If oven goes out after approximately 4
mins, this is due to a disconnected or open
circuit thermistor.
Oven fails to re-ignite after set 1. Incorrectly set spark electrode.
temperature is reached 2. Low Gas Pressure.
Oven fan fails to start 1. Open circuit in programmer.
burner does not light 2. Component failure on main board
3. Component failure at control board.
FAULT FINDING
Gas & Electrical connection
Please refer to installation instructions
for the Gas & Electrical Safety Regulations
and the Ventilation Requirements.
In your own interest, and that of safety,
it is the law that all gas appliances be
installed by competent persons, who
will ensure that the installation is in
accordance with “The Gas Safety
(Installation & Use) Regulations 1994”,
& the “The Gas Safety (Installation &
Use) (Amendment) Regulations 1996”.
Failure to comply with these
Regulations is a criminal offence.
Corgi registered installers undertake to
work to satisfactory standards.
Disconnection of gas and electric
appliances should always be carried
out by competent persons.
Warning: This appliance must be
earthed.
In the event of a power cut
1. Switch off the electricity to the
appliance at the socket.
2. When the power returns, see the
‘Programmer / Clock’ section to
‘Set the time of day’.
Note: operating the control knobs
You may find that the control knobs on your
new appliance operate or perform differently
to those you are used to.
The controls are part of the unique electronic
operating system of the appliance and are
designed to be extremely responsive and
easy to turn.
Condensation
When hot and cold air meet,
condensation forms. The outer door is
air cooled and the inner door gets hot,
so some condensation might form; this
is normal and will disappear within
10 - 15 minutes.
During operation, a metallic click may
be heard occasionally. This is caused
by the gas valve operating and is
quite normal.
Ventilation
The use of a gas cooking appliance
results in the production of heat and
moisture in the room in which it is
installed. Ensure that the kitchen is well
ventilated; keep natural ventilation holes
open or install a mechanical ventilation
device (mechanical extractor hood).
Prolonged intensive use of the
appliance may call for additional
ventilation, for example opening of a
window, or more effective ventilation,
for example increasing the level of
mechanical ventilation where present.
This appliance is not connected to a
products evacuation device.
It should be installed and connected in
accordance with current installation
regulations. Particular attention should
be given to the relevant requirements
regarding ventilation.
