Process validation
The standard of disinfection in the
disinfection programmes must be
confirmed by the user as a routine
matter.
In the UK, safety checks should be
carried out to the machine every 3
months by a Miele approved service
technician in accordance with EN ISO
15883 and HTM 2030.
Routine checks
Before the start of each working day,
the user must carry out a number of
routine checks. A check list is supplied
with the machine for this purpose.
The following need to be inspected:
–All filters in the wash cabinet
–The spray arms in the machine and
in the baskets
–The wash cabinet and the door seal
–The dispensing systems
– Baskets and inserts
If powder cleaning agent is being used,
the temperature at the time of
dispensing must be checked every two
weeks.
The dispensing temperature for
validation is set out in the validation
report.
Check the dispensing temperature as
follows.
During a programme sequence, check
the temperature which shows in the
display when you hear the container lid
spring open. Document this
temperature and compare it to the data
stated in the validation report.
,You must inform the Miele Ser-
vice Department if the dispensing
temperature displayed differs from
the temperature set out in the
validation report by more than
+/- 2°C.
