If you have a DC voltmeter and can see the contacts in the charger, you may be able to see it the charger has a output. But with the newer electronics for battery charging, the battery may need to be in the charger to get a reading. My guess is you do have a bad charger.

The battery falls slightly loose, so you have to fasten it securely to the body of the vacuum. I learned this from another user here on Fixya. He uses electric tape. I used one of those rubber bracelets that kids wear. Worked perfectly!

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.

If you'd like further advice from our experts after you've given this a try, please call the Dyson customer Helpline on 0800 298 0298 (UK), 1-866-693-9766 (US), or 1-877-397-6622 (CA).

Hi there, it's Jack at Dyson.

The issues with your DC44 Animal sound unusual, and we'd like to take some further details. If a replacement part is needed, we can also confirm if your machine is within our 2-year warranty period.

Hi Darren, it's Jack at Dyson.

I'm sorry to hear you're having difficulty recharging your DC44 Animal. It should charge from flat within 5.5 hours when connected to the charger assembly, or placed in the docking station, as shown in the video above.

The charge light will turn off once the battery is fully charged. If it seems to be shutting off prematurely, we would need to take you through some quick diagnostic checks when you have the machine to hand. This will help us confirm what may be needed to resolve the issue.

Please give the Dyson customer Helpline a call on 0800 298 0298 (UK), 1-866-693-9766 (US), or 1-877-397-6622 (CA), to speak directly with our team of experts.

Hi there, it's Jack at Dyson.
I'm sorry to hear you've had difficulty with your DC44 Animal. It's normal for air to blow out of the back of the machine - this is where the exhaust air is returned to the room after passing through the cyclone pack.
However, if your machine doesn't seem to be picking up as well as usual and you've recently washed the filter, this may be due to a blockage. To check the motorised carbon fibre floor tool, wand and bin inlet for any obstructions, please follow the steps shown in our online Support guide:
http://www.dyson.co.uk/support/dc44/dc44-animal/my-machine-is-not-working/machine-not-sucking-picking-up-as-well-as-usual-dc44/no-resolved-redirect-to-check-the-wand/check-wand
The motorised carbon fibre floor tool is driven by it's own motor, rather than the machine's airflow. If it isn't rotating, the video attached should help you locate anything which could be jamming the brush bar. Make sure you remove any threads or hair from around the brush bar carefully using scissors, taking care to avoid causing any damage to the bristles.
I'm confident this will resolve the issue, but if you would like some further help you can reach the Dyson customer Helpline directly by calling us on 0800 298 0298 (UK), or 1-866-693-9766 (US).
