Warning and Safety Instructions
16

Abrasive substances must not be placed in the machine as they
could cause damage to the mechanical components of the water
supply. Any residues of abrasive substances on items to be washed
must be removed without trace before reprocessing in the machine.

Pre-treating (e.g. with cleaning agents or disinfectants), some
types of soiling and the interaction of certain processing chemicals
can cause foaming. Foam can have an adverse effect on the cleaning
and disinfection results obtained.

The process must be set so that no foam escapes the wash
compartment. Escaping foam jeopardizes the safe operation of the
machine.

The process must be checked regularly in order to detect any
foaming.

To avoid the risk of damage to the machine and its accessories
caused by process chemicals, soiling and any reaction between the
two, please read the notes in "Chemical processes and technology".

Even when a chemical additive (e.g. cleaning chemical) is
recommended on technical application grounds, the machine
manufacturer takes no responsibility for the effect of such chemicals
on the material of the items being cleaned.
Note that formulation changes, storage conditions, etc., that are not
disclosed by the chemical manufacturer may adversely affect the
cleaning results obtained.

When using process chemicals, always consult the instructions
issued by individual manufacturers. Process chemicals must only be
used for the purpose for which they are designed by the
manufacturer to avoid any material damage or the occurrence of very
strong chemical reactions.

Always follow the relevant manufacturer's instructions on storage
and disposal of process chemicals.

Particles ≥ 0.8 mm are removed by the filters in the wash chamber.
Smaller particles may find their way into the circulation system. For
this reason, processing of wash loads with narrow openings requires
additional filtering of the wash water.

In critical applications where very stringent requirements have to
be met, it is strongly recommended that all the relevant factors for the
process (detergent, water quality, etc.) are discussed with Miele.

The carts, baskets, modules and inserts that hold the wash load
must be used only as intended.
Hollow items must be thoroughly cleaned, internally and externally.

Secure small and light items with cover nets or place in a mesh
tray for small items, so that they do not block the spray arms.
