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
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 burners
do not light up.
If your table is fitted with a gas
safety system and the flames go out
as soon as you release the control
knob.
In the low position the
flames go out or are
too high.
Flames are irregular.
The knobs get hot during cooking.

WHAT SHOULD YOU DO?
- 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 fixed to the worktop, make sure that the fixing 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.
- 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.
- Avoid any severe drafts in the room.
- Check that the gas you are using corresponds to the injectors that
have been installed (See injector identification in the "Gas Rating"
chapter).
Remember that gas hobs are delivered preset for use with natural gas.
Check the adjustment of the low power screw (See paragraph
"Changing the type of gas supply").
- Check that the burners and injectors are clean and assembled
correctly.
- Check you have enough gas in your gas cylinders.
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.
