Minor troubleshooting
You have doubts about whether your hob is working correctly.
This does not
necessarily mean there is a breakdown.
Nevertheless, check the following points.
IF YOU REALIZE THAT
WHAT SHOULD YOU DO
Lighting the burners:
There is no sparking
when the control knobs
or buttons are pressed
down.
When you only press
down one control knob
all the burners spark.
Sparking takes place
but the bumers do not
light up.
- Check the electrical connections on the hob.
- Check that the sparkers are clean.
- Check that the burners are clean and in position.
- If the hob is
fi
xed to the worktop, make sure that the
fi
clamps have not been twisted.
- Check that the sealing rings have not come out of place.
This is normal. The lighter system is centralised, and all the
burners spark at the same time.
- Check that the gas inlet pipe has not been squashed.
- Check that the gas inlet pipe tube is less than 2m long.
- Check that the main gas tap is open.
- If you use gas tanks or cylinders check that they are not empty.
- If you have just installed your hob or changed a gas cylinder,
keep the control knob wide open for a few seconds so that the
gas can get through.
- Make sure the injector is not blocked up. if this is the case,
clear it with a safety pin.
- Light up your gas-ring before putting a pan on it.
If your table is
fi
tted with
a gas safety system and
the
fl
ames go out as
soon as you release the
control knob.
- Push the control knob down completely and keep it under
pressure for a few seconds after the burner has lit.
- Check that the burner parts are in place.
- Check that the sealing rings under the control knobs have not
come out of place.
- Avoid any severe drafts in the room.
- Light the burner before putting your pan on it.
In the low position the
fl
ames go out or are too
high.
- Avoid any severe drafts in the room.
- Check that the gas you are using corresponds to the lnjectors
that have been installed (See injector identi
fi
cation in the “Gas
Rating” chapter).
- Remember that gas hobs are delivered preset for use with
town gas.
- Check the adjustment of the low power screw (See paragraph
“Changing the type of gas supply”).
Flames are irregular.
- Check that the burners and injectors are clean and assembled
correctly.
- Check you have enough gas in your gas cylinders.
The knobs get hot
during cooking.
Use small pans on the burners next to the control knobs. Large
pans are to be put on the large burners furthest away from the
knobs. Put the pan in place with the burner in the middle. The
pan should not be above the control knobs.
