Food is cooking too slowly, too quickly, or burning
Cooking times may differ from your previous oven. The oven control settings
and cooking times are intended to be used only as a guide. Individual tastes
may require the gas mark to be altered one gas Mark either way, to get the
results you want. Try cooking at a higher shelf position and/or higher Mark.
Oven cooking times and temperatures may need to be increased when other
burners are in use. Are the Main oven burner ports blocked with spilt food?
The oven is not cooking evenly
Do not use a tin or baking tray larger than 340mm x 305mm in the main oven or
232mm x 321mm in the Tall oven.
If you are cooking a large item, be prepared to turn it round during cooking.
If more than one shelf is used, check that space has been left for the heat to
circulate. When a baking tray is put into the oven, make sure the front edge is
level with the front of the shelf.
Check that the door seal is not damaged and that the door catch adjusted so
that the door is held firmly against the seal.
NB the seal is intended to have a gap at the bottom of the door
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 when turned on manually
Problems with the burner (main oven)
Are the oven burner ports blocked with spilt food? Are the burner flames
starting low and then rising to full height?
Electrical Problems
Is the power on? Is the clock illuminated? If not there may be something wrong
with the power supply. 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 button twice.
If 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.
Steam is coming from the Tall oven
When cooking foods with a high water content (e.g. oven chips) 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.
The Tall oven fan is noisy
The note of the oven fan may change as the oven heats up - this is perfectly
normal.
