Turns Itself Off

This is the symptom of an overheating motor. The motor can be overheating due to either a blockage, usually in the cleaner head or hose, dirty filters or most likely a worn motor.


PLEASE NOTE: If your are in anyway unsure of any of the steps listed below. Please consult a qualified electrician and always remove the plug from the socket before commencing work.



1. Start by detaching your Dyson's cyclone/bin assembly.

2. Then unlatch the pre motor filter cover.

3. Underneath the pre motor filter cover you will find the blue/yellow pre motor filter. Which can now be removed.

4. Next remove the wheels by placing a large flat screwdriver into the gap between the DC08's body and the wheel. Ensure that the screwdriver is placed as close to the centre as possible before prising the wheel off.

5. Using a Torx T15 screwdriver. Remove the six retaining screws holding the upper motor cover in place.

6. Then split the upper motor cover from the lower motor cover. Take a moment to examine the layout of the motor and cable inside the casing.

7. Disconnect the brown (Live) wire and the the blue (Neutral) wires and then carefully withdraw the motor from the casing.

8. Using a large flat screwdriver gently prise back the locating tabs to remove the motor bucket top from the motor bucket.

9. Once the motor bucket top is removed the motor seal can then be withdrawn.

10. The motor will then easily come away from the motor bucket. Next, disconnect the motor wires red to brown (Live) and black to blue (Neutral). Then remove the motor plate (Blue arrow) and motor bearing (Red arrow).

11. Examine the motor for wear or damage. Pay particular attention to the commutator (The copper segments where the carbon brushes contact the motor - red arrow). If the commutator is blackened and heavily scored the motor must be replaced. Also pay attention to the bearings on the motor. The armature shaft should turn easily with the fingers with very little resistance other than the resistance of the carbon brushes touching the commutator ring. If the bearings are stiff or make a grinding noise the motor must be replaced.

Reassembly is a simple matter of reversing the steps listed above.
