A friend of mine is having this weird issue with his Dyson V6 Car + Boat handheld vacuum cleaner, which he bought two years ago. He stated that it was acting screwy. Turns out the motor is constantly cutting out during use. This happened the other day.

For the record, the bin and filters were cleaned the day before this occurred, and nothing is clogging any openings in the vacuum.

He made a short video of this issue, which he granted me permission to upload. What should we do?

It's clearly an electronic problem. At least the symptom is, anyway. The computer is attempting to ramp up the motor, doesn't like what it sees (for whatever reason), turns it off, and tries again, but a maximum of seven times. That's programming at work.

Likely the controller is not receiving an input it expects, for example a speed signal from the motor, or an airflow or suction signal, etc. Speaking strictly from knowing how electronically controlled devices operate, I'd wager either a bad sensor, or bad control unit. Really no way to be sure without complete disassembly to make sure no other hidden issues.

I wonder if the light blinking is blinking an error code number. Count the blinks.

Possible solution?

It sounds like the pre-motor filter is clogged internally. I'll have to let my friend know about that.

Someone on YouTube suggested watching this video from 1:25 onward to see how the filter should be separated and what's actually inside it. Apparently, the motor pulsing and cutting out is supposed to happen in the event of a blockage.

Like I said, the computer is expecting to see something and it isn't. Like an airflow signal that it wouldn't get if there was a clogged filter.

I would try running it in your hand (not on the floor) with no filters in it at all. See if it still has the problem, if the problem goes away, then you know your filters are shot (clogged or possibly non-oem that is too dense and choking off the airflow)

I doubt very much that its an electronic problem. My V8 has done this numerous times, even after taking out the filter and washing it, letting it dry and put it back it.

Take the filter off at the top of the cyclone and run the machine again to see if it is still doing this.

You might need to remove the cage from the filter to give it a 'proper' clean as Dysons instructions only show washing it from the outside. The Dyson Expert I work with showed me how much fine dust a crap can built up inside the filter that is not normally accessible by just washing as per Dysons instructions.

Also make sure your bin flap opens and closes properly.

See my video below of my V8 doing this after a filter wash and dry. The solution was to put it on Max and put my hand over the end rapidly to get to eventually start working.

Perhaps you missed the spot where I said the SYMPTOM is an electronic problem. Not the cause.

Hey guys

My friend got his vacuum to work again. He watched the second video I posted. I did tell him that he's not supposed to hit the trigger when emptying the bin.

Definatly check the filter first, I've had about 10 in this year alone with just that issue (including the one linked to on the video above!). Then it's the battery, although cheap pattern batteries are very cheap now and work fine.

But wash the filter properly before spending money.
