Problem Solving; Aftercare - Hoover HH74DBXP User Instructions

A FEW HINTS:
Frequent cleaning leaves a protective layer which is essential to
prevent scratches and wear. Make sure that the surface is clean
before using the hob again. To remove marks left by water, use a few
drops of white vinegar or lemon juice. Then wipe with absorbent paper
and a few drops of specialised cleaning fluid.
The glass ceramic surface will withstand scraping from flat-bottomed
cooking vessels, however, it is always better to lift them when moving
them from one zone to another.
NB:
Do not use a sponge which is too wet.
Never use a knife or a screwdriver.
A scraper with a razor blade will not damage the surface, as long
as it is kept at an angle of 30°.
Never leave a scraper with a razor blade within the reach of
children.
Never use abrasive products or scouring powders.
. The metal surround : to safely clean the metal surround wash with
soap and water, rinse, then dry with a soft cloth.
Any change in the colour of the glass-ceramic surface does
not affect its operation or the stability of the surface. Such
discolorations are mostly a result of burnt food residues or
use of cookware made of materials such as aluminium or
copper; these stains are difficult to remove.

8. PROBLEM SOLVING

The cooking zones do not simmer or only fry gently
Only use flat-bottomed pans. If light is visible between the pan and the
hob, the zone is not transmitting heat correctly.
The pan bottom should fully cover the diameter of the selected zone.
The cooking is too slow
Unsuitable pans are being used. Only use flatbottomed utensils, that
are heavy and have a diameter at least the same
as the cooking zone.
Small scratches or abrasions on the hob's glass surface
Incorrect cleaning or rough-bottomed pans are used; particles like
grains of sand or salt get between the hob and the bottom of the pan.
Refer to the "CLEANING" section; make sure that pan bottoms are
clean before use and only use smooth bottomed pans. Scratches can
be lessened only the cleaning is done correctly.
