Chemical process

general information
Effect
Damage to elastomer (seals and hoses)
or plastic components of the machine
may cause the materials to swell,
shrink, harden or become brittle, and
cracks may form in the materials. This
will impair their function and lead to
leaks.
Strong foaming prevents proper
cleaning and rinsing of the load. Foam
escaping from the wash compartment
can result in damage to the machine.
If foaming occurs, the cleaning process
is NOT standardized and NOT
validated.
Corrosion in the stainless steel of the
washing compartment and accessories
has various appearances:
– rust formation (red spots / stains),
– black spots / stains,
– white spots / stains (smooth surface
is slightly corroded).
Corrosion that forms holes can lead to
leaks in the machine. Depending on the
application, the corrosion may impair
the cleaning and rinsing results
(laboratory analysis) or cause corrosion
of the load (stainless steel).
