Turns Itself Off (Models WITHOUT Brush Control)

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.

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.

FILTERS - Always check the filters first. Start by examining the pre motor filter (The blue sponge filter in a yellow carrier). If the pre motor filter is dirty then wash it warm soapy water or replace it. To examine the pre motor filter start by depressing the catch at the top of the cyclone top assembly handle and removing it from the Dyson.

1. Carefully pull up the catch located at the bottom of the cyclone's top handle and then rotate the lid backwards.

2. Remove the pre motor filter from it's housing. Separate the blue sponge filter from the yellow carrier and wash both parts thoroughly in warm soapy water. Only refit to your Dyson once both parts have completely dried.

Next, check the post motor filter (Located below the bin). If the post motor filter is dirty it must be replaced, it cannot be washed.

3. Remove the post motor filter lid by inserting a flat bladed screwdriver under the locating tabs at the front and sides of the lid. Use the screwdriver to gently prise the tabs on the post filter lid, off the main body.

CHECK FOR BLOCKAGES - 7. Lay your Dyson onto it's back and, using a two pence piece or a large flat screwdriver, turn each of the three soleplate fasteners a quarter of a turn in an anti-clockwise direction.

1. Start by laying 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 prising it away from the cleaner head, underneath the centre soleplate fastener.

3. Using a large screwdriver carefully prise the belt from the motor shaft.

 

4. Pull the brush roll out of the cleaner head.

5. Lay the Dyson onto it's side and remove the internal hose. By first pulling at the point where it is connected next to the U-bend.

 

6. Then by unwinding the other end from the brush holder.

 

7. Remove the ubend from the rear of the Dyson.

 

8. Lay the Dyson onto it's side and remove the brush holder by gently rocking it from side to side whilst pulling it away from the cleaner head.

 

9. Remove the other side by using the same method.

 

10. Using a large flat screwdriver. Gently remove the two large plastic circlips holding the cleaner head in place. One on each side.

 

11. Hold the cleaner head firmly in both hands and gently open the sides to clear the cleaner head from the main body.

 

12. Carefully remove the bearing clip from the left side of the Dyson.

 

13. Then remove the bearing clip from the right side.

 

14. Remove the cyclone/bin assembly.

 

15. Remove the post motor filter lid by prising it free with a screwdriver and then remove the post motor filter. Which lies beneath the lid.

 

16. Using a Torx T15 screwdriver. Remove the 4 screws holding the upper motor cover onto the main body.

 

17. Gently pull the upper motor cover and motor housing free of the main body.

 

18. Remove the Upper motor cover by holding each side and gently spreading the sides to clear the motor housing.

 

19. Using a large flat screwdriver gently prise off the motor retaining ring.

 

20. Grasp the black fancase seal and pull the motor free of the motor housing. (This may require a considerable force)

 

21. When you have removed the motor from it's housing. Take careful note of the correct connection of the wires. Red to Brown (live wires), Black to Blue (neutral wires).

22. Remove the offset motor bearing mount and the rubber fancase seal from the old motor and fit them to the new motor.

.............................. REASSEMBLY ...............................

23. Before refitting the motor to the motor housing. Lubricate the rubber seal with a very slight smear of vaseline to allow the motor to be manouvered into place.

 

24. When refitting the motor ensure that the offset motor bearing mount is correctly alligned so that the large protusion lines up with the large cut out of the motor housing.

The rest of the reassembly is a simple reversal of the steps listed above.
