Is the power on? Is the clock illuminated?

Is the key symbol ( ) showing in the display? See 
the Clock section of the instructions for more 
information on the key lock feature of the clock.

If using the Multi-function oven have you set a 
cooking function?

If not there may be something wrong with the 
power supply. Is the cooker supply on at the 
isolator switch?

Timer set correctly but oven knob left OFF by 
mistake?

Is the key symbol ( ) showing in the display? See 
the Clock section of the instructions for more 
information on the key lock feature of the clock.

If using the Multi-function oven have you set a 
cooking function?

If turning the knob down has not worked or only 
worked for a short time then you may need a 
new thermostat. This should be fitted by a service 
person.

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 pan 
pushed fully back to stop? 

When you pull the 

grill pan forward is the 

wide rim at the front? 

It's important that the 

wider part is at the front.

The bulb has probably blown. You can buy a 
replacement bulb (which is not covered under the 
guarantee) from a good electrical shop. Ask for an 
Edison screw fitting 15w 240v lamp, FOR OVENS. It 
must be a special bulb, heat resistant to 300 °C. See 
the 'Customer Care' leaflet for spares by mail order.

 Turn off the power supply.

Make sure the oven is cool. Open the oven door 
and remove the oven shelves.

Unscrew the bulb cover by turning anticlockwise. It 
may be very stiff.

Taking care to protect your fingers in case the bulb 
should shatter, unscrew the old bulb. 

Screw in the new bulb, screw back the bulb cover. 
Turn on the electricity supply and check that the 
bulb now lights.
