Maintenance
Always clean off any liquid as soon as it is spilt. This will
prevent food remains from sticking to the hob surface and you
will save yourself any unnecessary effort.
After each use, clean the surface of the respective burner parts
once they have cooled down. If any residue is left (baked-on
food, drops of grease etc.), however little, it will become stuck
to the surface and more difficult to remove later. The holes and
grooves must be clean for the flame to ignite properly.
The movement of some pans may leave metal residue on the
pan supports.
Clean the burners and pan supports using soapy water and
scrub with a non-wire brush.
Do not clean individual parts of the appliance in the
dishwasher.
Always dry the burners and pan supports completely. Water
droplets or damp patches on the hob at the start of cooking
may damage the enamel.
Caution!
The stainless steel cleaner must not be used in the area around
the controls. The (printed) symbols may be wiped off.
Thoroughly remove spilt cooking oil and acidic foodstuffs such
as lemon immediately.
Under no circumstance should abrasive cleaning powder be
used to clean the control panel. The inscriptions can be
scratched off as a result.
The burner caps are coated with black enamel. Due to the high
temperatures, discolouration may occur. Their burner function
is not adversely affected by this.
