If everything is working well regarding the power supply, but you still witness the issue, try the next solution.
Check the Wall Switch:
Over time, the contacts in a wall switch might get dusty or rusted. Again, the plastic or metal parts inside the wall switch may become loose and allow it to move around. This can prevent the power socket from making a good connection with the contact points on your Dyson vacuum’s power cable. To fix this, you need first to check your switch. Firstly, remove the faceplate from the wall switch. Then clean any debris or dust you see using a cloth. You need to turn off the power supply before trying all of it, and a simple mistake can get you electrocuted. After cleaning and tightening everything inside the wall switch, put the faceplate back and turn the power on.
Try the next solution if your Dyson V11 or V12 is still not turning on or getting any power.
Check the light:
When you try to turn on your Dyson Vacuum cleaner, if you see a blue light, it could be possible due to a blockage. You need to thoroughly clean the vacuum in many ways to ensure that there is no blockage causing the issue. You can try cleaning the HEPA filter of your Dyson vacuum cleaner and check whether that allows the vacuum to turn on again.
If cleaning out the vacuum cleaner does not work, move on to the next solution.
Red light showing up:
When you try to turn on your Dyson vacuum cleaner, if you see a red light, the trouble is with the device’s battery. The best way to fix this is to replace the battery of the vacuum cleaner entirely.
Ensure you get the new battery from Dysin itself, as it would be best compatible with your device. Further, ensure that when you replace the battery, it is done correctly and everything else is in its proper place.
If changing the battery does not solve your problem, move on to the next solution.
Dyson is not showing any light:
If you do not see a blue light or a red light while plugging in the vacuum cleaner to a power source, that could also indicate a battery problem. It happens only when the vacuum cleaner is not receiving any power at all. In such a scenario, the solution mentioned above about replacing the battery is your best bet in fixing the Dyson V11 or V12.
If this does not work as well, move on to the next solution.
Inspect The Power Cables:
The cable you are using to connect your vacuum cleaner to the power source needs to be in working condition. Ensure that the cable fits well at both ends with no gap between the port and the cable. Even the smallest gap can cause the vacuum cleaner not to turn on.
You also need to check the cable for any visible damage. If there is any tear in the cable or any part of it looks burnt, you need to change it. You can find such a cable in any electrical store near your house.
If the vacuum turns on after changing the power cable, you have your solution. The power cable was indeed the culprit. But if the vacuum cleaner does not turn on even after changing the cable, try the next solution.
If none of the solutions mentioned above worked for you, the problem is with your Dyson vacuum cleaner’s hardware. In that case, you need to contact Dyson support. You can find information on contacting them right on their website. You can also visit the nearest Dyson service centre and try to get the device fixed. If it is under warranty, you may even get it replaced by them for free.
