Clearing blockages
Disconnect your machine from the charger before looking for blockages.
Be careful not to touch the trigger and be aware of sharp objects.
Leave your machine to cool down before looking for blockages.
Don't use your machine when looking for blockages as this could cause
injury.
Remove the bin and check for blockages in the main body of your machine.
Make sure any blockages are completely cleared and all parts are fitted
before using your machine.
If your machine detects a blockage, the motor will pulse and you won't be
able to use your machine until the blockage has been cleared.
If you try to use your machine when the motor is pulsing, it will automatically
cut out.
To check for blockages in the main body of the machine, remove the bin
following the instructions in the Cleaning your bin section and remove the
blockage.
If you cannot clear an obstruction, you may need to remove the brush bars.
Refit all parts securely before using your machine.
Clearing blockages isn't covered by your guarantee.
With the bin removed,
check for blockages, paying
particular attention to the air
inlet, located at on the right–
hand side of the machine just
below the point where the bin
joins the main body of the
machine.
With the wand
removed from the
machine, check for
blockages at both ends
of the wand.
Turn the cleaner
head over to check
for obstructions on
the brush bar and air
inlet.
