Problem How to resolve it
The ingredients in process chemicals have
a strong influence on the longevity and
functionality (throughput) of the dispensing
systems.
- Follow the process chemical
manufacturer’s instructions and
recommendations.
- Carry out a regular visual check of the
dispensing system (suction lance, hoses,
dispensing canisters, etc.) for any
damage.
- Regularly check the flow rate of the
dispensing system.
- Ensure that the regular cycle of
maintenance is observed.
- Please contact Miele for advice.
Process chemicals can damage elastomers
and plastics in the machine and
accessories.
- Follow the process chemical
manufacturer’s instructions and
recommendations.
- Carry out a regular visual check of any
accessible elastomers and plastics for
damage.
The following process chemicals can cause
large amounts of foam to build up:
- detergents and rinse aids containing
surfactants
Foam can occur:
- in the program block in which the process
chemical is dispensed
- in the following program block if it has
been spilt
- in the following program with rinse aid if it
has been spilt
- The process parameters in the wash
program, such as dispensing temperature,
dosage concentration, etc., must be set
to ensure the whole process is foam-free
or very low-foaming.
- Please observe the process chemical
manufacturer’s instructions.
De-foaming agents, especially silicone-
based ones, can cause the following:
- deposits in the wash cabinet
- deposits on the wash items
- damage to elastomers and plastics in the
machine
- damage to certain plastics (e.g.,
polycarbonate and plexiglass) in the wash
items
- 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 wash
items and without de-foaming agent using
the Special 93°C-10' program.
- Please contact Miele for advice.
