Remove the spray arms as follows:
Remove any mobile units from the wash cabinet.
Loosen the securing clip on the spray arm connection, then pull the
lower spray arm upward and the upper spray arm downward.
Loosen the securing clip on the spray arm connection and then pull
the spray arm downward.
If there is considerable visible wear on the spray arm bearings, con-
tact Miele Technical Service as this can result in functional prob-
lems.
Reinsert the spray arms after cleaning, then secure them with the
securing clips. Ensure that the securing clips are seated correctly.
After replacing the spray arms, check that they rotate freely.
 Unsatisfactory cleaning results due to an incorrectly measured
spray arm speed.
There are powerful magnets at the end of the spray arms. If metal-
lic objects get stuck on these magnets, this can cause a false read-
ing of the spray arm speed.
Remove any metallic objects which are stuck to the magnets, such
as instrument parts.
