6. Troubleshooting

Cooktop ignition or cooktop burners faulty
Is the power on?
Are the sparker (ignition electrode) or burner holes
blocked by debris?
Are the burner heads correctly located? See the section
entitled 'Cleaning'.
Remember that each cooktop burner has a special flame
safety device (FSD) that stops the flow of gas if the flame
goes out. When lighting a cooktop burner the safety
device has to be overridden by holding in the control
knob so that the gas can flow. This allows the flame
sensor to heat up and operate the safety device. Keep
holding the knob pressed in to let the gas through to
the burner for few seconds. The igniter should spark and
light the gas.
If, when you let go of the control knob, the burner goes
out, the safety device has not held in. Turn the control to
the off position and wait one minute, then try again this
time holding in the control knob for slightly longer.
Cooktop burners will not light
If only one or all the cooktop burners will not light,
make sure that the 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 in the control
knob? If not check the power is on.
Steam is coming from the oven
When cooking foods with a high water content (e.g.
oven fries) there may be some steam visible at the rear
grille. Take care when opening the oven door, as there
may be a momentary puff of steam when the oven
door is opened. Stand well back and allow any steam to
disperse.
An oven fan is noisy
The note of the oven fan may change as the oven heats
up – this is perfectly normal.
What cleaning materials are recommended for the
cooker?
See the 'Cleaning' section for a full list of recommended
cleaning materials.
We do not recommend corrosive or caustic cleaners
n n
as these may damage your cooker.
The knobs get hot when I use the oven, can I avoid this?
Yes, this is caused by heat rising from the oven, and
heating them up. Do not leave the oven door open.
If there is an installation problem and I don't get my
original installer to come back to fix it who pays?
You do. Service organizations will charge for their call
outs if they are correcting work carried out by your
original installer. It is in your interest to track down your
original installer.
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 rack positions. See the oven cooking
guide section of the instructions.
The oven control settings and cooking times are
intended to be used only as a guide.
Individual tastes may require the temperature to be
altered either way, to get the results you want. Try
cooking at a higher temperature setting.
The oven is not cooking evenly
If you are cooking a large item, be prepared to turn it
round during cooking.
If two racks are used, check that space has been left for
the heat to circulate. When a baking sheet is put into the
oven, make sure it is placed centrally on the shelf.
Check that the door seal is not damaged.
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.
Oven not coming on
Is the power on?
If not there may be something wrong with the power
supply. Is the cooker supply on at the circuit breaker?
Have you set a cooking function?
