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

It needs a replacement battery or check the output of charger, may need to get an electrical experienced person for this with an volt meter

Hi Emma, it's Jack at Dyson.

I'm sorry to hear your DC44 Animal doesn't seem to be working correctly. If the green LED indicator on the machine lights up, but the machine itself doesn't run, this suggests the battery is flat. It could mean that it's not recharging correctly when connected to the docking station.

It would be worth temporarily disconnecting and removing the charger cord from the docking station and plugging it directly into the machine - the machine should recharge fully within 3.5 hours. If the machine then works as normal the charger cord may not have been corrected fitted to the docking station.

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.

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:

it needs charging . and if the lights dont light when you put it in the charger somthing is wrong with charger or battery

Hi its Darran at Dyson.

From your description of the problem, it sounds as though there is a problem with the battery.

Your DC16 will have been supplied with a 2 year guarantee. If it still within this period, please contact our Helpline on 0800 298 0298. However if your machine is no longer covered, a replacement battery can be purchased via our website at www.dyson.co.uk/store.

Kind regards

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.

smething internal is burnt out possible bad battery.
