Unsatisfactory cleaning results
Unsatisfactory cleaning results may ap-
pear as drying spots, or as spots that
look like corrosion.
Presumably corrosive spots often are
bio-debris. They have the shape of dry-
ing spots, blurry edges, and the color
of rust. Bio-debris may also appear on
surfaces that were not decontaminated
before processing.
Please observe:
^
Have the instruments been stored in
the washer/disinfector for more than
6 hours? If so, please run the
washer/disinfector, even partially
loaded, within 6 hours of loading.
^
Was enough detergent used? Please
check the dosage of the detergent
and adjust, if necessary. Too little as
well as too much detergent may de-
teriorate the cleaning results.
^
Can both spray arms rotate easily,
when the washer/disinfector is
loaded? If not, please rearrange the
goods to be cleaned in a way so that
the spray arms can rotate freely.
The water in the wash cabinet is not
heated; the cycle lasts too long
This washer/disinfector has a resettable
temperature sensor which will shut off
the heating elements in the case of
over-heating. This could be caused if
large articles cover the heating ele-
ments or if the filters in the wash cabi-
net are blocked.
^
Remove the cause of overheating.
^
Take off the service panel (see "In-
stallation").
^
Press in the blue reset button on the
temperature sensor.
If this switch trips repeatedly, contact
the Miele Technical Service Department
before using the washer/disinfector fur-
ther.
