Troubleshooting
Oven 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? Is the clock flashing 0.00? If
so, set it to the correct time of day. Has the Timer been set to AUTO by mistake? If
AUTO is showing on the clock display, press the 'cook period' button and reduce any set
cooking time showing to 0.00, with the (+) and (-) buttons. Press the
this does not solve the problem contact a service person.
Oven not coming on when automatic cooking
Timer set correctly but oven knob left OFF by mistake?
Oven temperature getting hotter as the cooker gets older
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.
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 fully back to stop?
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 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
HELP leaflet for spares by mail order.
Open the oven door and remove the Handyrack (if fitted) and oven shelves.
Unscrew the bulb cover by turning anticlockwise. 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.
Unscrew the old bulb and fit the new one.
Hotplate ignition or hotplate burners faulty
Is the power on? Is the clock illuminated? If not there maybe something wrong with the
power supply.
See 'power supply' section further on.
Are the sparker (ignition electrode) or burner slots blocked by debris?
Is the burner trim correctly located?
Are the burner caps correctly located?
See the section entitled 'Cleaning'
Hotplate burners will not light
If only one or all the hotplate 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 the button? If not check the power is on - is the
clock illuminated?
Turn off the power supply.
