My cordless dyson will start but after about 30seconds it will cut out and two little blue lights flash, I've checked for blockages and cleaned the filter but still does it. Any suggestions?

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.

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.

try washing the filter in the washing machine then try again

Hello, this is Ava with Think Crucial.

There are a number of things you need to do that may solve the issue you're having with your vacuum. First, make sure that your battery is charging and working. Second, check the MAX button. If the MAX button lights up and flashes when your Dyson cordless vacuum keeps pulsating on and off, hold the power button and depress the MAX button to turn off that function. You may have to try a few times to get the hang of it. And lastly, look for any blockages in attachments because the pulsating is caused by a lack of airflow as the motor is protecting itself by pulsating and then ultimately cutting out.

You can check this video tutorial which will teach you on how you may fix it:

Hi

Thanks for making contact and I'm sorry you're having difficulty.

I would suggest that this is a blockage of some kind as the pulsating is caused by a lack of airflow (the motor is protecting itself by pulsating and then ultimately cutting out).

I would recommend looking at the following video which will take you through a methodical way of checking this. The model in the video is a DC59 but applies to most cordless models: https://www.youtube.com/watch?v=fdnu4yk-5vI

Furthermore, I would check the bin inlet to make sure that the one-way door/flap is not jammed as this also can cause the problem.

If you continue to have difficulty, please give the Dyson Helpline a call on 1-866-693-9766 (US), 1-877-397-6622 (CA), 0800 298 0298 (UK). Our experts will be happy to talk you through some further diagnostic checks when you have your machine easily to hand.

Best wishes

Hi Barbara, it's Jack at Dyson.

In order to confirm why your DC35 may not be running correctly when fully charged, we'd need to take you through some simple diagnostic checks when you have your machine easily to hand. If a replacement part is needed, we can also confirm if this is covered under your Dyson warranty.

When you have a moment, please give our experts a call on 0800 298 0298 (UK), 1-866-693-9766 (US), 1-877-397-6622 (CA) or 1800 239 766 (AU) so we can provide further assistance.

This is a sure sign of a blockage. The motor cuts out because it gets too hot and will start again when it has cooled. Follow the instructions in your user manual for clearing blockages (you can download a copy from the Dyson website if necessary). Make sure the washable filter is clean too (and completely dry before you use it).

most vacuums have a heat resister in when they overheat they cut out, this is normally because they are full up, got a blockage or the filters need cleaning, suggestions are, clean filters, empty and check for blockage.
