Miele DA 430-4 EXT Operating And Installation Instructions page 20

Both the outer filter and the grease filter
should be cleaned.
An oversaturated filter is a fire
hazard.
To avoid damaging the outer filter,
the grease filter or the hob below,
make sure you hold the filters
securely at all times when handling
them.
^ To remove the outer filter, pull down
on the quick-release catches at the
front and release from the hooks at
the back. Take care not to let the
outer filter fall onto the hob.
^ To take out the grease filter, release
the locking clip on the filter, lower the
filter 45°, unhook it at the back and
remove it.

^ Clean the grease filter and the outer
filter with a soft nylon brush in a mild
solution of hot water and a little
washing-up liquid.
Do not use "neat" washing up liquid.
Do not use:
– cleaning agents containing
descaling agents,
– alkaline cleaning agents (with a pH
value higher than 7), such as powder
cleaners, cream cleaners or abrasive
all-purpose cleaning agents,
– oven sprays.
^ Place the filters with the short side
upright in the lower basket, and wash
on a 65° programme using a mild
dishwasher detergent, ensuring the
spray arm is not obstructed.
Avoid alkaline dishwasher detergents
(with a pH value higher than 7).
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.
