Cleaning and care
Cleaning the grease filters by hand
^ Clean the filters with a soft nylon
brush in a mild solution of hot water
and a little washing-up liquid.
Do not use undiluted washing up
liquid.
Do not use:
– cleaning agents containing
descaling agents,
– powder cleaners, cream cleaners or
abrasive all-purpose cleaning
agents,
– oven sprays.
Cleaning the grease filters in the
dishwasher
^ Place the filters as upright as
possible in the lower basket. Ensure
the spray arm is not obstructed.
^ Do not wash at more than 65 °C. If a
Miele dishwasher is being used,
select the Sensor wash programme.
^ Use a mild dishwasher detergent.
Depending on the cleaning agent
used, cleaning the filters in a
dishwasher can cause permanent
discolouration to the surface.
However, this will not affect the
functioning of the filters in any way.
^ After cleaning, leave the filters to dry
on an absorbent surface before
refitting them.

^ When removing the filter for cleaning,
also clean off any residues of oil or
fat from the now accessible casing to
prevent the risk of these catching fire.
^ When putting the grease filters back
in position, ensure that the locking
clips are facing down towards the
cooktop.
If a grease filter is inadvertently
refitted upside down, insert a small
screwdriver blade into the slit to
disengage the clip.
^ To reset the operating hours counter
for the grease filters, press and hold
in the Grease filter touch control for
approx. 3 seconds.
The indicator lamp for the touch
control will go out.
If the grease filters are cleaned before
the operating hours counter has
reached its maximum, you can reset
the operating hours counter by
pressing and holding in the Grease
filter touch control for approx. 6
seconds.
