Chemical Processes And Technology - Miele PG 8527 Operating Instructions Manual

General notes
Problem
If seals, hoses and plastics in the
washer-disinfector suffer damage they
will not be water-tight and will not
function correctly.
Heavy foaming during a programme
affects cleaning and rinsing results.
Foam escaping from the wash cabinet
can cause damage to the
washer-disinfector.
Cleaning processes cannot be
regulated and validated where there
has been a build-up of foam.
Corrosion to stainless steel in the wash
cabinet and to accessories can give
them a different appearance:
– Rust (red marks / discolouration),
– black marks / discolouration,
– white marks / discolouration (etched
surface).
Corrosive pitting can lead to the
washer-disinfector not being
water-tight. Depending on application
corrosion can influence cleaning and
rinsing results (laboratory analysis) or
cause corrosion to stainless steel items
in the cabinet.
