Problem How to resolve it
De-foaming agents, particularly silicone-
based de-foaming agents, can cause the
following:
– deposits to build up in the wash cabinet,
– deposits to build up on the load,
– damage to elastomers and plastics in the
machine,
– damage to certain plastics (e.g.
polycarbonate and plexiglass) in the load
being processed.
– De-foaming agents should be used in
exceptional cases only, for instance when
absolutely essential for the process.
– The wash cabinet and accessories should
be periodically cleaned without a load and
without de-foaming agent using the
Organic program.
– Please contact Miele Service for advice.
Soiling
Problem How to resolve it
The following substances can damage
elastomers (hoses and seals) and plastics in
the machine:
– Oil, wax, aromatic and unsaturated
hydrocarbons,
– emollients,
– cosmetics, hygiene and care products
such as creams (analytical applications,
filling).
– Depending on usage wipe the lower door
seal on the machine periodically with a
lint-free cloth or sponge. Clean the wash
cabinet and accessories without a load
using the Inorganic program.
– Process the load using the Oil program
program (where this is available) or use a
special program that dispenses
emulsifiers.
The following substances can lead to heavy
built-up of foam during washing and
rinsing:
– some disinfection agents and
dishwashing detergents.
– reagents for analysis, e.g. for microtiter
plates,
– cosmetics, hygiene and care products
such as shampoos and creams (analytical
applications, filling).
– active foaming agents such as tensides.
– Thoroughly rinse items in water
beforehand.
– Select a cleaning program with at least
one short pre-rinse in cold or hot water.
– Depending on application use antifoaming
agents that do not contain silicone oils.
