In the event that your Dyson suddenly switches off and won't turn back on again then go through these steps.
First check your socket, try something you know that works like a lamp in the socket if that doesn't work check your circuit breaker. If in doubt consult a qualified electrician.
If you have ruled out an electrical problem in your house then firstly check your Dyson's fuse, only replace it with a 13A fuse which is usually brown in colour. If you replace it with a smaller fuse it will blow that fuse immediately and lead you down the garden path to a problem that may not exist.
Admittedly the correct fuse blowing is quite rare unless the motor has failed.
The most common cause of no power is the machine overheating and cutting out.
In this case once the vacuum cleaner loses power leave it for at least half an hour and then try turning it back on again. If it comes back on again after an hour then clean your filters and check for blockages. See our suction problems repair page.
A word of warning if your vacuum cleaner switches off and then on again every few seconds TURN IT OFF IMMEDIATELY AND DO NOT USE IT until it has been repaired, this indicates a cable problem and it will blow a small hole in the cable eventually (sometimes a large hole)
If it is a blocked filter or a blockage causing it to overheat it will turn off and not come back on again for at least half an hour so if it turns off and on every few seconds then it is a serious electrical problem that needs to be repaired.
Usually it is the main cable that you plug in, the cable breaks were it enters the vacuum cleaner and this causes it to cut in and out quickly. Best option is to replace the entire cable.
DO NOT KEEP USING IT while wiggling the cable even though you really need to get that last bit of carpet done, is it worth getting shocked for?
90% of the time it will be the mains cable causing it, 9% of the time the switch and the other 1% it is either the motor, internal cable or thermal cutout causing it.
If your vacuum cleaner had a strong acrid burning smell before it lost power then the chances are the motor has failed which will require a motor replacement.
