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
fronts
Clean with stainless steel cleaner and a soft cloth. Always wipe 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, scouring sponges and rough cleaning cloths are not suit-
able. The stainless steel fronts can be polished using a special care product. Follow the manufacturer's
instructions. You can purchase special stainless steel cleaner from our after-sales service or from specialist
retailers.
Enamel surfaces and
lacquered surfaces
Clean with some washing-up liquid and a damp cloth. Dry with a soft cloth.
Gas burners and
steel grids of the gas
hob
Do not clean in the dishwasher. Remove the steel grids and clean them with a sponge, washing-up liquid
and some hot water. Remove the burner cup and lid. Clean with a sponge and some hot water and wash-
ing-up liquid. Ensure that the gas openings in the burner cups are clean and free from dirt particles. The
igniters must be cleaned with a soft brush. The gas burners only work properly when the igniters are clean.
Remove food residue from the burner shells with a cloth and some hot soapy water. Only use a little water.
Water must not be allowed to enter the appliance. Ensure that the nozzle opening does not become
blocked or damaged during cleaning. Dry all parts after cleaning and place the burner cover accurately on
the burner cup. Burner ignition may be hampered by individual parts that do not sit correctly. Attach the
steel grids again. You can purchase the recommended special cleaner for cleaning the steel grids from our
after-sales service or from specialist retailers.
Electric hob (option) 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 residues immediately.

The metal ring may discolour over time. However, it is possible restore the original colour. Clean the ring
with the hard side of a scouring sponge and some liquid scouring agent. When doing so, make sure that
you do not scour the adjacent surfaces, as this could damage them. You can purchase the recommended
special cleaner for cleaning the metal ring on the electric hotplate from our after-sales service or from spe-
cialist retailers.
