Frequently asked questions / Technical service The vacuum cleaner shuts off automatically. A warning light § comes on to indicate overheating. A temperature sensor will turn off the vacuum cleaner if it becomes too warm. This is indicated by a thermal protection indicator § on the display panel of the vacuum. This problem can occur if, for example, an object is blocking the suction hose or the filter bag pores have become clogged with fine dust. The cause could also be a heavily soiled exhaust or dust compartment filter. If this happens, turn off the vacuum cleaner (press the On/Off foot switch s) and unplug the power plug from the electrical outlet. Once the cause has been addressed, allow the vacuum cleaner to cool for approx. 20 - 30 minutes before resuming vacuuming. Technical service In the event of a fault which you cannot fix yourself please contact the Miele Service Department at the phone number listed on the back of this booklet. ^ Please quote the model type of your appliance. This can be found on the data plate on the bottom of the vacuum. 32
