Power failure.
In the event of a failure in the electrical supply,
remember to reset the clock to ensure that the timed
oven continues to operate.
Food is cooking too slowly, too quickly, or burning.
Cooking times may differ from your previous
oven. Check that you are using the recommended
temperatures and shelf positions - see the oven cooking
guide. Then adjust the settings according to your own
individual tastes.
The oven is not cooking evenly.
Do not use a baking tray with dimensions larger than
those specified in the section on 'General Oven Tips' .
If you are cooking a large item, be prepared to turn it
round during cooking.
If two shelves are used, check that space has been left for
the heat to circulate. When a baking tray is put into the
oven, ensure that it is placed centrally on the shelf.
Check that the door seal is not damaged and that the
door catch is adjusted so that the door is held firmly
against the seal.
A dish of water when placed on the shelf should be the
same depth all over. (For example, if it is deeper at the
back, then the back of the cooker should be raised up or
the front lowered). If the cooker is not level arrange for
your supplier to level it for you.
The timed oven is not coming on when turned on
manually.
Is the power on? Is the clock illuminated? If not, there
may be something wrong with the power supply. Is the
cooker supply on at the isolator switch?
Has the time of day been set?

Is the key symbol ( ) showing in the display to signify
that the oven is locked? See the 'Clock' section of the
instructions for more information on the key lock feature.
The timed oven is not coming on when automatic
cooking.
Has the oven knob been left in the OFF position by
mistake? Is the oven locked (see above)?
Oven temperature getting hotter as the cooker gets
older.
If turning the temperature down using the oven control
knob has not worked, or has only worked for a short
time, then you may need a new thermostat. This should
be fitted by a service person.
The oven light is not working.
The bulb has probably blown. You can buy a
replacement bulb (which is not covered under the
guarantee) from most electrical stores. Ask for an Edison
screw fitting 15W 240V lamp, FOR OVENS. It must be a
special bulb, heat resistant to 300°C. See the HELP leaflet
for spares by mail order.
Before removing the existing bulb, turn off the power
supply and ensure that the oven is cool. Open the oven
door and remove the oven shelves.
Locate the bulb cover and unscrew it by turning it
anticlockwise (it may be very stiff ).
Now unscrew the existing bulb anticlockwise, taking
care to protect your fingers with a glove in case the bulb
should shatter.
Screw in the new bulb clockwise and then screw the
bulb cover back on. Turn on the electricity supply and
check that the bulb now lights.
Hotplate ignition or hotplate burners faulty.
Is the power on? Is the clock illuminated? If not, there
maybe something wrong with the power supply.
Are the sparker (ignition electrode) or burner slots
blocked by debris?
Are the burner trim and caps correctly located? See the
section on 'Cleaning' .
Hotplate burners will not light.
Make sure that the burner parts have been replaced
correctly after wiping or removing for cleaning.
Check that there is not a problem with your gas supply.
You can do this by making sure that other gas appliances
you may have are working.
Do the burners spark when you push the button? If not,
verify that the power is on by checking that the clock is
illuminated.
