    I have the same problem with my Dyson. The charger says it's charging for about an hour and then all 3 lights are flashing, and when I take it out of the charger... nothing.



    Before this problem though, while I was cleaning the floor, I let go of the trigger, and the machine just kept running until it died.



    Supposedly Dyson does have an issue with their batteries, and customer service should send you a new battery replacement

Ok, folks.. I just posted my own problem with the battery not holding it's charge..but, we fixed it ourselves.. take the motor loose from the canister , remove the filter and in the back are two contacts.they are two screws at the bottom one on each side... get out your pencil with a GOOD eraser and clean those contacts!..clean around them both and the contact (silver spot at the bottom) and you're good to go!!

Eureka!

My root has been working intermittently for ages but now it's as good as new.

I removed the battery and gave a squirt of good old WD 40 on the metal contacts and now it works perfectly.

    THE 3 flashing light problem and not holding charge??? CHECK THESE TO SEE IF IT HELPS. In my case I had the filter facing the wrong way. Here are the tips from the official dyson.

    A few things that may help to ensure the machine is functioning as
    intended is make sure the filter is free of debris and positioned
    correctly in the machine. Positioned correctly means that the blue
    sponge is facing away from the black motor cover, and the blue and white
    plastic screen is positioned with the small hole in the lower left of
    the blue plastic is positioned over the plastic "pin" that sticks out of
    the main body of the machine.


    It is also important that the machine is being charged vertically with
    the nozzle facing toward the ceiling. This allows the contacts on the
    machine to make a full connection with the contacts on the charger.

...so then you attempt a recharge and the scene is repeated? ...then the internal battery needs replacing, but a weak charging circuit may also be a culprit...problem best found by measuring DC charging current

I took the battery out and cleaned all the contacts between battery and machine and battery and charger (ie. contacts on all 3 bits) with a kids clean small stiff bristled nylon paintbrush, and seems to be running continuously now - it was cutting out every 2-3 secs before

Keeps stopping even though I have taken it apart and checked for blockages. +


Are you sure your wall charger is working ok? You might just have a bad battery pack in the sweeper if your charger is working. Do you have a friend who knows electronics and has a voltmeter?

If so, have them check the voltage output of the charger at the plug that goes into the sweeper. Verify that the charger is indeed working ok. Then you will need to check the voltage on the battery pack inside the sweeper to see if your battery is good and holding a charge. A mechanical blockage could be something caught in the vacuum fan blade. You should be able to hold the main part of the sweeper up to your ear so you can hear and then pull the sweeper trigger and see if you can hear the motor try to start. Nothing happening may mean a dead battery pack. Regards, Dennis

I have a Dyson DC16 handheld and the battery does not hold a charge.


I have the same vaccumm with the same problem, went back to exchange it and the same thing happened, I usually get about 10-15 minutes non stop out of the battery, I read that the battery memorizes the first charged time and then will only charge for that long. Did you happen to charge it 24 hrs?

My dyson handheld charges fully, but keeps cutting out when using. About 7 seconds is the longest continual usage time


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 replace the battery.
Shorting the battery like an Aircraft battery then re-charging won't fix it.

Battery lasts only 3 - 4 minutes. Dyson admits this is too short, but won't send me a new battery because I live in Canada..


yer its a con and they know it too, rember it takes about 16 hours to fully charge the batterys after they have been knocked flat, and thats only with a good set in it,,, problem is in your battery pack there are whats called "matched batterys" that is the batterys all hold the same amount of charge if one go's down on you the hole pack is a bust bin job as you wont ever get the same kind of battery to replace it with

Hi, this is our third Dyson DC-16.. the Trigger was shorting out on the first two.. Now we have the third one for about a year.. on charge when not using it.. don't use it every day, but for quick pickups...


How are you charging your battery? Every battery has a memory. If you dont let it die the first come times then charge to full the battery will assume 40% is 100%.

Removing the battery


The battery is located at the bottom of the handle. To release it, press and hold down the button on top of the battery case (it has 3 ridges on it). That releases a catch and you can then slide the battery out to the rear.
