A crack has appeared in the hob surface
Disconnect the cooker immediately from the power

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.
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.
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 organisations 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 shelf 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 shelves 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.
