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.

1. Firstly check that the filters are clean.
2. Check for blockages in the cleaner head and hose.

If, after doing both of the steps above, you can find no obvious reason for the cleaner to overheat then inspect the motor for damage by following the steps detailed below.

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. Lay your Dyson onto it's back and, using a two pence piece, turn each of the three soleplate fasteners a quarter of a turn in an anti-clockwise direction.

2. Remove the soleplate by twisting either side of the centre plastic screw.

3. Grasp the brush Roll in the centre and carefully pull it away from the cleaner head.

4. Carefully rotate the brush roll to 'unwind' it from the belt. You must take great care doing this as the edges are very sharp where the belt passes through the brush holder. It is sometimes beneficial to first remove the black plastic end cap from the brush roll.

5. Lay the Dyson onto it's right side and prise off the glamour cap (Hub cap) from the wheel.

6. Then remove the circlip holding the wheel onto the axle.

7. After removing the wheel, use a Torx T15 screwdriver to remove the three screws holding the clutch cover in place. When removing the clutch cover be careful not to break the rubber soleplate seal (Blue arrows).

8. Very carefully pull the rubber soleplate seal from the groove in the clutch cover.

9. Remove the clutch cover from the cleaner head.

10. Using a flat bladed screwdriver, carefully remove the belt from the motor shaft.

11. To remove the cleaner head from the main body it is necessary to lay the Dyson onto it's left side and rotate the cleaner head downwards so that the notch in the cleaner head (red arrow) lines up with the peg on the main body (blue arrow).

12. Remove the cleaner head by gently pulling the sides apart.

13. Using a Torx T15 screwdriver, remove the eight screws holding the lower motor cover in place.

14. Pull the lower motor cover away from the main body and take note of the position of the motor and the layout of the wires in the main body.

15. As you withdraw the motor take note of the position of the motor plate.

16. After withdrawing the motor. Take note of the correct connection of the wires, brown to black (live) and blue to white (neutral). Then remove the motor plate and the rubber fancase seal (fitted to the bottom of the motor) from the old motor ready to be fitted to the new motor.

Reassembly is a simple reversal of the steps listed above.
