The dust compartment of the vacuum cleaner is dirty. When you open the lid, you can see that the dust compartment is very dirty. The fan might be defective.
Open the filter frame until you hear it click and remove the old motor protection filter, taking hold of it by the clean, unsoiled section.
Replace with a new motor protection filter.
Close the filter frame.
For the avoidance of faults, we recommend using Miele FilterBags.
Insert the new FilterBag into the holder as far as it will go, until you hear it click into place.
Leave the FilterBag folded up when you take it out of the box.
If you open the top part of the vacuum cleaner, make sure that the FilterBag is still seated correctly inside the appliance before you close it.
Even when correctly fitted, the FilterBag (new or used) can be pulled out of its holder when the top part of the appliance is opened.
To check that the FilterBag is seated correctly inside the appliance, proceed as follows:
Remove the vacuum cleaner hose.
Check that the FilterBag is seated through the suction.
If the hygiene flap is open, the FilterBag is seated correctly in the holder.
If the hygiene flap is closed, seat the FilterBag correctly.
Pull the FilterBag holder up.
The tabs on the FilterBag holder are now on top of the side ribs in the dust compartment.
Incorrect operation can result in the FilterBag holder being bent significantly out of shape.
As a result, dust will get into the dust compartment despite the FilterBag being seated correctly.
To prevent dust from getting into the dust compartment, the FilterBag holder must close completely.
The FilterBag holder needs to be replaced.
