Question about Dyson DC16 Root 6 Bagless Handheld Cyclonic Vacuum

2 Answers

My dyson DC16 constantly shuts off even when battery is fully charged. I cleaned the filters to see if that was the problem. It only runs for a few seconds before it shuts off. It will run intermittently for about 10 minutes before dying completely. Please advise

I do not have a solution to the short run, and I have run into the same problem with my Dyson. I purchased a replacement battery which solved the problem for 1-1/2 years, then it reappeared. Another new battery solved it. I now have realized that the battery is always charging while in the wall storage holder, and being a Li-ion, they do not like that. When I use the vacuum, I am now putting it back in the charger, and letting it charge until all 3 lights are on, and then I put a business card where the contacts for charging are at the top of where the charger meets the vacuum, and when correctly placed, the lights go out, indicating that I have interrupted the circuit. I have put the date on the battery, and will see if this extends the life of the battery.

My dyson shuts off after just a few seconds of run time.


Make sure the charger is operating. Then if it is, look at a failed battery.

When is the DC16 red light supposed to change to green?


You can see the manual for the DC16 here: (
https://www.dyson.co.uk/medialibrary/Files/Dyson/Support/downloads/UK/floorcare/Manuals/dc16_uk_manual_cb_120710%20pdf.pdf )

Following the troubleshooting manual on page 6, fully charging the battery takes about 3 hours, for a run time of 6 minutes, so I'm not sure where 10 minutes comes from. The battery ships partially charged and was supposed to have been charged 3+ hours before a first use to get a full cleaning span.

It's also noted that you can get red lights if the temperature is out of an optimal range, and if the filter is not seated properly, so these would be things to check as well.
On the general checking list - look at the contacts for the battery and for the charger, make sure nothing is bent or corroded. Corrosion can be generally treated with use of some fine sandpaper or steel wool - be sure to blow the area clear of any steel wool fibers if you go that route. A better electrical contact sometimes will allow charging to get above a threshold voltage that will let the 'I'm charged' light turn green.

Good Luck! :-)

Red light flashing constantly on dc16 when on charge, used to just stay permantly red without flashing until it went green when charged up.


I had a similar problem when I bought an after market 2Ah battery. Would stay solid red for a few seconds then flash red. I believe my problem was that the battery had gone into "sleep mode" I.e. it was discharged to the point that it "sleeps" in order to protect itself. So......I simply attached a domestic DC multi adapter to the terminals on the battery that are marked + and - (the 2 outside terminals on a DC16 Dyson battery). Switched on the DC adapter for around 10mins and this was enough to "wake" the battery. It now charges as normal attached to the DC16 in the Dyson charge mount.

For a pretty in depth article on lithium battery sleep have a look at this:

Fully charged, filters cleaned, vacuum keeps shutting down in and then starts again only to shut off again. the 6 minute time limit is not used up.


Your battery is losing voltage too quick. It has probably developed a 'memory'. Dyson claims that their handheld has the best suction out of all the handhelds out there. In order to maintain that claim the circuit board will shut off power to the motor when the voltage drops below adequate charge for full suction.
We need someone who can teach us to bypass that part of the circuit so it won't cut power to the motor or you need to get a new battery.
Shorting the battery like an Aircraft battery then re-charging won't fix it.

My DC 16 will only run for a second each trigger pull. The battery is fully charged, it has plenty of suction, just wont run for more than a second. I cleaned the filters.


I had the same problem with my Dyson DC16, where it only runs for a few seconds at a time with each trigger pull. My husband called Dyson (Canada) and without hassle they shipped us a replacement part which I just received this morning. The replacement part sent to us is: DC16 Main Body with Rating Plate. It is also under warranty for 1 year. The great customer service makes up for the flaw in the machine. Also, Dyson is aware of the problem. Hope this helps.
