Interference with and repairs to the hob MUST NOT 

be carried out by unqualified persons. Do not try 

to repair the hob as this may result in injury and 

damage to the hob. Please arrange for repair by a 

suitably competent person.

A crack has appeared in the hob surface

Disconnect the cooker immediately from the power 

supply and arrange for its repair. DO NOT use the cooker 

until after the repair.

My hob is scratched

Always use the cleaning methods recommended in this 

guide and make sure that the pan bottoms are smooth 

and clean.
Marks from mineral deposits from water or food can be 

removed with a cleaning cream. However, tiny scratches 

are not removable but will become less visible in time as 

a result of cleaning.

The oven fan is noisy

The note of the oven fan may change as the oven heats 

up – this is perfectly normal.

Grill not cooking properly

Are you using the pan and trivet supplied with the 

cooker? Is the pan being used on the runners, not the 

floor of the compartment? Is the grill tray pushed back 

fully to the ‘back stop’ position?

The knobs get hot when I use the oven or grill. Can I avoid 

this?

Yes, this is caused by heat rising from the oven or the 

grill, and heating them up. Do not leave the oven door 

open. Make sure that the grill pan is pushed right back 

to the ‘back stop’ when grilling.
Always grill with the grill compartment 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 organisations will charge for their call-

outs if they are correcting work carried out by your 

original installer. Therefore, it is in your own interest to 

keep track of this installer so that you can contact them 

as required.

Power failure

In the event of a failure in the electrical supply, 

remember to reset the clock to make sure 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, make sure 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 [

F

] 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.
