Maintenance covers the following
points:

– connectors and fittings in the wash
comparment,

– internal and external dispensing
systems,
– spray arms,
– filter combination,
– collector with drain pump and
non-return valve,
– steam condenser,
– all mobile units, baskets, and inserts,
– the drying unit,
if applicable:
– the external printer.
During maintenance, the following
function checks are run:
– a program test run,
– electrothermal measurement,
– seal testing,
– all safety-related measurement
systems (fault report)
– the safety features.
Process validation
It is the responsibility of the operator to
routinely check that the required
cleaning and disinfection processes
are functioning properly.
In some countries, this is also required
by national legislation, regulations, or
recommendations.
Operators are also required to conduct
such checks under international stan-
dard
EN ISO 15883-1
(CAN/CSA-Z15883)
.
Routine checks
Before each day's use, the operator
must conduct a series of routine
checks. A routine checklist is supplied
with the washer-disinfector.
The following items must be checked:
– the filters in the wash cabinet,
– the spray arms in the
washer-disinfector and on the
baskets and inserts,
– the wash cabinet and the door seals,
– the mobile units, baskets, and
