Why isn't it charging?

First check it is fully charged. Secondly, Try checking all the pipes, tubes and attachments for blockages. Basically take it to bits and clean it. Dyson have a 'cut out' feature fitted to stop you burning out the motor when it's blocked up.

That's dyson's way of laughing at you for spending 4 times as much as you should have for a vacuum that doesn't work any better than the rest of them

not trying to be a smart a** but which of the two do you have?
1. A flashing blue light indicates that the battery is running low on charge.
2. A fast flashing blue light indicates no power or a temporary fault (e.g. check filter or for blockages).

FYI....A solid blue light indicates that the battery is charging. No light indicates the battery is fully charged. A solid amber light indicates that the battery is not charging due to a temporary fault (e.g. too hot/cold). A flashing red light indicates that there is a fault, call the Dyson Helpline.
Best to you.

Hello, this is Ava with Think Crucial.

There are a number of reasons why your Dyson cleaner is pulsating off and on. First, it can be due to a battery of the cleaner. Make sure that the power cable is properly plug to the power and seated properly from the unit while charging. If you find that the battery isn't charging at all, you may need to replace the battery. Second is to check the MAX button of your cleaner. If the button lights up and flashes when your Dyson keeps on pulsating, press and hold the power button and depress the MAX button to turn off the function. You may need to do it for a few times to get the hang of it. Third is to check for any blockages or clogs in the attachments. Look down through the tube and check to see if there are clogs on the sweeper end or if the roller is tangled up in fibers. Clean the roller brush are if it it's necessary. You may need to empty the dust bin of your unit as debris can build up in hard to reach places. Lastly, cleaning the filters may fix the pulsating of your cleaner. Remove the filter and rinse it with cold water and air dry it for 12 hours. Don't use detergent when washing your filters. If the pulsating doesn't go with the given quick fix, I suggest to contact Dyson for further assistance on this.
