Miele S140 - Manual (Page 36)

The vacuum turns itself off
If the vacuum detects an airflow prob-
lem, it will shut itself off in order to pre-
vent the motor from over heating.
This can occur anytime the airflow
through the machine is impeded. A full
or clogged dustbag, clogged filters, or
clogged wand or accessory can cause
this safety feature to activate. If this oc-
curs, turn off the vacuum and check for
any blockages. After 20 to 30 minutes,
the vacuum will reset itself, allowing you
to turn it on and use it.
