Question about Dyson Vacuums

1 Answer

Dyson DC16 all three lights flashing while in charger, and does not work outside of charger (appears battery fully drained).

DC16 was working, but show low charge (red light). I put it in the charger and plugged in, started blinking red (normal while charging)... then yellow and red, back to just red, and then all three lights started blinking in a span about 3-4 minutes. Now DC16 does not work at all, and no lights on when trigger is pulled both outside of charger cradle and inside charger cradle.

UNIT WILL ONLY RUN FOR FEW SECONDS THEN THE BOTTOM OF THE 3 LIGHTS WILL FLASH


Hi there,

I'm sorry to hear you're having difficulties with your DC16. A single flashing red light indicates that the battery needs to be recharged. When fully charged, all 3 LEDs should illuminate without flashing. However, if the red light continues to flash even after at least 3 hours recharging time, there may be a fault with the battery or charger assembly.

Please get in touch with us directly - one of our experts will be happy to run through some troubleshooting over the phone with you to determine whether the battery or the charger requires replacement. You can call us free on 08002980298 (UK), or 1866MYDYSON (US). We'll look forward to hearing from you.

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:

My hand held Dyson vacuum will not charge. Every time I attempt to us it I get 3 charge light on the side flash?


My same symptoms are - after starting charge, Red light is on, then second light turns On. Then for a long time nothing happens. And later I have all three LED flashing.
I replaced battery and nothing changed.

Imeasured Power Supply voltage and found it 24.2v instead 28v as it stated on the label.

I opened it up and found that the three-lid chip marked 431 is faulty.
431 is a voltage shunt, which sets and controls output voltage.
You can use AIC431CUS or TL432 (TL431 has different pinout).
I replaced mine and volatge back to 28.25v and charger is now working as it should.

You can also use any TO-92 431 chip - there is enough room for it.

Good luck!

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...


Hi its Darran at Dyson.

My DC16 will start and then stop. I have to take


My DC16 also had charging problems. I called Dyson and they sent a new charger. The old charger only produced 23.6 volts DC, not the rated 28 volts DC. The new charger has a thicker round wire and produces 28.1 volts DC. Put a volt meter on your charger terminals and see if it is producing enough voltage to fully charge the battery, 28 volt DC. If not you need a new charger.
