Cleaning and care
Cleaning the grease filter
^ By hand: use a scrub brush with a
solution of warm water and mild
detergent.
Do not use the pure detergent,
aggressive all purpose cleaners,
oven sprays, abrasive cleaning
agents or limescale removers. They
could destroy the filter.
^ In a dishwasher: place the filter
vertically in the lower basket, making
sure that the spray arm is not
blocked.
Use a hot temperature program,
e.g. "Heavy Soil" or "Pots and pans".
Use the recommended amount of
dishwasher detergent. Overuse could
destroy the filter.
Depending on the detergent,
cleaning the grease filters in a
dishwasher may cause permanent
discoloration of the filter surface.
Performance of the filter will not be
affected by this discoloration.
^ After cleaning, the filters can be
placed on a towel to air dry.
^ While the filters are removed, clean
any dirt or grease from the filter
casing to prevent the risk of fire.

When putting the grease filters back
make sure that the locking clips are
visible facing down towards the
cooking surface.
If the filters are incorrectly installed,
insert a small screwdriver into the slit
along its edge to disengage it from the
casing.
^ After returning the grease filters,
press the grease filter button for
3 seconds to reset the timer. The
indicator light will go out.
^ If the grease filters are cleaned
before the timer has reached its
maximum, the grease filter button
should be pressed for 6 seconds to
reset the counter to zero.
