Cleaning and maintenance
For the cooking area to have optimum power and a long
service life, thorough cleaning and maintenance are essential.
As a safety precaution, turn the gas off at the gas cylinder
controller. (If the cooker is set up to use natural gas, close the
natural gas tap).
Unplug the appliance from the mains.
If the burner is still hot, let it cool down first.
Caution!
■ Do not use any high-pressure cleaners or steam jets.
■ When cleaning the cooker, do not use any flammable
substances such as acids, diluting agents, petrol or benzene.
■ Under no circumstance should abrasive cleaning products or
materials be used, which may cause scratches.
Cleaning
Damage to the various different surfaces caused by using the
wrong cleaning agent can be avoided by observing the
following instructions.
When cleaning the hob do not use
■ undiluted washing-up liquid or dishwasher detergent,
■ cleaning agent with a high alcohol content,
■ scouring pads,
■ abrasive cleaning agents such as oven cleaner or stain
remover,
■ Do not use caustic or abrasive cleaning agents.
■ Do not clean individual parts in the dishwasher.
Wash new sponges thoroughly before first use.
If the pan supports are fitted with rubber rests, ensure that
these are also cleaned. The rests may come loose and the pan
support may scratch the hob.
After cleaning and drying the steel grids, ensure that they are
correctly fitted.
Stainless steel sur-
faces* (depending
on the appliance
model)
Clean it with stainless-steel cleaning agent and a soft cloth. Always wipe stainless steel surfaces parallel to
the natural grain. Otherwise, you may scratch the surface. Dry with a soft cloth. Always remove any flecks of
limescale, grease, starch and egg white immediately. Harsh cleaning products, scratchy sponges and
rough cleaning cloths are not suitable. You can use special care products to polish the stainless steel
fronts. Follow the manufacturer's instructions. Special stainless-steel cleaning agents are available from the
after-sales service or from specialist retailers.
Enamelled, painted
and silkscreen sur-
faces* (depending
on the appliance
model)
Wipe with warm soapy water and a cloth. Dry with a soft cloth.
Gas burner and steel
grid
Do not clean in the dishwasher. Remove the steel grid and clean this using a sponge, some hot water and
washing-up liquid. Remove the burner casing and burner cap. Use a sponge with some hot water and
washing-up liquid to clean these. Ensure that the gas openings on the burner casing are clean and free
from dirt particles. Clean the igniter with a small, soft brush. The gas burners only work properly when the
igniters are clean. Use a cloth and some hot soapy water to remove the food remains from the burner cas-
ing. Only use a little water for this. Water must not get into the interior of the appliance. Ensure that the jet
opening is not blocked or damaged during the cleaning process. Dry all of the parts after they are cleaned,
and place the burner caps exactly onto the burner casings. Individual parts that are not correctly positioned
make it difficult for the burner to ignite. Place the steel grid back into its position. The cleaning agent that we
recommend for cleaning the steel grid is available from our after-sales service or specialist retailers.
Glass hob* (depend-
ing on the appliance
model)
Care: Protective/care products for glass

Remove the protective cover and clean using the blade only. Caution, the blade is very sharp. Risk of injury.
Cover the blade again after cleaning. Replace damaged blades immediately.
Electric hotplate*
(depending on the
appliance model)
Clean with the hard side of a scouring sponge and some liquid scouring agent. After cleaning, switch the
hob on briefly to dry it. Wet hobs rust over time. Then apply a care product. Always remove spilt liquids and
food residue immediately.
Metal hotplate ring*
(depending on the
appliance model)
The metal ring may discolour with time. However, the original colour can be restored. Clean the ring with the
hard side of a scouring sponge and some liquid scouring agent. Do not touch the adjacent surfaces. These
may become damaged. The recommended cleaning agent for the metal ring on the electric hotplate is
available from our after-sales service or specialist retailers
