How to Fix a Dyson DC44 not Charging

[@robertcasey7312]

I've been searching for a video to enable my Dyson repair. Must have seen a hundred. Your video is exactly what I needed. Sincerely appreciated. Best Wishes!

[@comeinhandynow]

Thanks

[@Everlanders]

In an effort to charge our Dyson Vac from a DC source in our camper, I came here looking for the charge connector pinout. I didn't understand why they would need 25 and 18 volts. I was happy to see that only two pins were connected and am currently charging with a DPH5005 power supply set to 24.35VDC - Interestingly, the power supply indicated it's pulling nearly an amp at the start and after 10 minutes, it tapers off to about 400mA

[@Everlanders]

I suppose a rational reason for the 18 volts and 24 volts in the same wall adapter would be for compatibility between other products, perhaps other models need the 18 Volt supply and this would allow them to use the same adapter for several products.

[@verbatim1144]

Thanks, very informative video. Seems like a joke that some are critical. I'm a mechanical engineer and like learn more about electronics by repairing things like this. Most other videos just scratch the surface, so it's nice to find one like this.

[@comeinhandynow]

Thanks

Amazing they charge $500 for these vacuums yet use $2 chargers.

[@thunderboltkid]

Thanks, Awesome job diagnosing, finding and fixing root cause of the charging problem descirbed in the video using the volt meter showing the interior workings of the battery electrical connections, my Dyson DC45 Animal is now fixed and charging properly, thanks to your thorough examination, much appreciated. Fyi-, now knowing what you described, I cheated a bit with a quick fix, noticing with high powered reading glasses and good light, the interior contacts had twisted from repeated insert and spin of the connector in one direction, so, without taking the whole battery apart, I simply twisted the connector around first clockwise then counter clockwise in socket until the light went on the battery connected wall charger, the twisting of the connector in the opposite direction of the connector typical spin when plugged in, essentially both re-aligned and also scrubbed the interior outer ring female receptor copper pins to be more firmly and cleanly touching the male outer cylinder contact wall of the plug head insert, and voila this method worked, for how long this quick fix works will depend on how well I re-seated and cleaned the copper tip surfaces with this simple, fast reverse spin action fix method to re-position and clean the copper connectors. The number of successful plug-ins made over time will be the metric to measure success , we will find out and report back. So the root cause of the 'not charging' problem over time, where the light on the charger does not go on, even thought the lights on the DC45 Animal do go on but do not have sufficent charge to run the motor, is as follows, its the repeated plugging in the male connector the same way with the Animal tilted on the same angle which causes the male connector to spin in one direction , over time twisting the female outer ring, centre facing copper pins somewhat diagonally and away from the the male plug wall, losing contact enough to have the integrated circuit electrical bridge not trip and open with enough voltage pressure. Long term Stow and Charge Mount Solution? imo, make sure the plug cable is first hook mounted and hanging exactly vertical on the wall to drop the plug directly into the female socket of a vertically mounted Vacuum so the male connector head does not spin inside the female socket, not ideal, but this vertical alignment of male to female mount solution securing the cable so it dos not twist is the remedy to get much longer life out of your Animal. :) Thanks a bunch!

[@comeinhandynow]

Thanks and thanks for your input.

[@thunderboltkid]

Dyson, please use a Power over USB connector for charge connection and data to fix the above in your future models to improve MTBF Mean Time Between Failure and your overall product reliability. RCA style jacks are such an old school cheap Chinese hi volume production shite approach to design and planned obsolescence to fatten share holder returns through unnecessary accessory sales (batteries and chargers, sold by dealers in the know or not, the latter does not matter, buyer beware at the retail level) . Dyson, you guys already charge enough for your products under your patent protections. For what people are paying the Dyson line should last like a House Furnace and have same warranty under normal use. 15 years with expected life of 20-25 years with proper maintenance. That said, I love your products, they are generally durable and work extremely well. However, You can do better.

[@thunderboltkid]

@@comeinhandynow Excellent job. :)

Thank you! Found and fixed loose charging connection thanks to this video. My 10+ year old DC44 is working again.

[@comeinhandynow]

Nice to read, thanks.

[@y000ks]

Same here! I was about to pull the battery but I saw the part about the charger cable and tried that first. Fixed! Thanks!

[@comeinhandynow]

@@y000ks Great, well done.

[@fergferguson7370]

Thanks after watching I’ve gained great insight to the workings and I’m just going to purchase a new one..good job jimmy👍

[@comeinhandynow]

It may just be the charger cable or battery. If you don’t want to fix you could try buying those.

[@Mike-01234]

Thanks didn't even realize the charger had a light on it because the way it was plugged into a 3 way adaptor back was pointed to the side. After plugging it in so I could see the light just like yours move the wire around and the green charge light goes off and on. Ill just order another charger.

[@steveburesh8585]

Thanks, good job. Only concern is shorting the terminals on the battery connector with your screwdriver when trying to improve it. Tinker-on!

[@billpickard3260]

Excellent video . I had no green light on the wall charger same as you . However rather than dismantle and suspecting oxidation like yours I sprayed WD 40 into the plug socket on the Dyson . Job done . Thanks again

[@comeinhandynow]

Thanks. Well done.

[@rodneytamblyn]

Worked for me too. Tip: wait 30 min after applying before confirming charge it may take some time.

[@RB-ss1dq]

I congratulate you on stripping the Dyson down and hunting for the fault.. If it's knackered and in need of replacement (in some peoples eyes) then there's no harm in taking it apart and having a go.. Seeing as its destined for the bin if you don't attempt to fix it. But there is one part you should have done differently.. When you stripped down the charging socket inside the battery housing, you then suggested scraping the contacts clean with a screwdriver. There was clearly no risk of harm to yourself from a 22v battery pack, but there was risk of shorting out the battery. There was a cable connector on the circuit board that you should have unplugged before you shorted the inner and outer contacts with that screwdriver. Luckily no damage appears to have been caused, but in some cases it could have popped the battery or a component on the circuit board. And like other people say, its easy to get replacements, but you don't get with that is the satisfaction of fixing it yourself. Doesn't make any difference if u have the money for a replacement or not, its still a bonus if u fix it. Keep up the good work

[@comeinhandynow]

Thanks for your good input and encouragement. You could be right about the short risk on some appliances, although on this model the battery current flow in a reverse direction back to the socket is prevented by the charge control electronics as demonstrated at 6:15 as the voltage goes back to 0v when the charger disconnects.

[@guppywibble3752]

Mine turned out to be the electrical contacts on the tub that holds the dust. They were gunked up. Bit of alcohol on a qtip and jobs a good un. Thankfully hoover don't seal the battery up and it's easily accessible by simply pressing a button.

[@nutzeeer]

Great help! Would you re do the video starting with the charger cable? Because that also was my problem and i took apart the battery for no reason :P

[@comeinhandynow]

Thanks, yes I should perhaps change the order to avoid that, but it was just done in the order it happened.

[@comeinhandynow]

Thanks. I agree.

[@blank069]

A better design would eliminate the need for any repairs or spending money on new batteries/power supplies but they wouldnt make much money then would they?

[@JP-nb7tm]

They put moulded plugs onto appliances because the average person can’t even safely change a plug. Encouraging people to do their own electrical repairs is not a good idea.

[@Tad1945]

All looks very technical.

[@berthaguerra8207]

Thank you so much 😊 is really $$$$ to buy another one

[@rosielee9973]

Less talking and more action thank you!!!!! He had made a right mess of the battery.

[@comeinhandynow]

Body is forcing you to watch it, so fast forward or change channel!!!!! Go elsewhere.

[@ardwych4881]

That's just silly, rosie, your comment. He describes everything he's doing as he goes. Words and visuals complement each other. You'd miss the explanations if they weren't given. Best to read his comment. Just a quick note, cihn, and I appreciate Ytub technique has progressed since you made the video, but I encourage you not to add a 'Thanks' comment for every compliment. It all takes us time. 8 secs each. The new heart serves the purpose well. And thanks 🙂

[@grahammackenzie2936]

It's probably worth sticking a multimeter on the plug first before doing this. I'm getting charge through my plug but but the thing itself won't charge. New battery in the post but if that doesn't work I'll be dissecting too!

[@comeinhandynow]

Agreed. The trouble with intermittent broken connections is that when I first did that it showed a voltage so it lead me off in the wrong direction initially. Aftermarket new batteries are fairly cheap.

[@grahammackenzie2936]

I actually had the exact same thing happen as you. I installed the new battery (we needed a new one anyway as it wasn't lasting a house clean). It still wouldn't charge after this. I prised open/demolished the dyson plug and got a burning smell. The thing is air tight so the smell must have stayed there until I opened it. There's a circuit board with various resistors on it in the plug, but a white square box in the middle of the board had fried. Lesson learned - even if a dyson plug shows voltage, it doesn't mean it's going to work!

[@comeinhandynow]

Interesting, thanks. It’s often electrolytic capacitors that fail, which may be that box. Does it have any marking on it?

[@grahammackenzie2936]

It didn't, but here's a (slightly blurry) photo if you're interested. I did it last weekend and threw it away unfortunately. imgur.com/a/0TS90Jt

Should have used plastic trim removal tools. Vacuum would still look like new. You can get them from Amazon for next to nothing.

[@comeinhandynow]

I’ve got some, but they weren’t strong enough for this.

[@lovejahandlive8912]

Fantastic video thanks so much for sharing i have exactly the same issue and gonna give this a try on my battery. Thanks for the efforts on making the video!

[@comeinhandynow]

Thanks, you are kind.

[@riddley39]

I am 100% certain it is my wire as the green light does not come on and previously worked after I wiggled the cable. However where would I get that small bit of wire to connect to the red wire? Looks quite difficult to be honest

[@comeinhandynow]

You can buy wire from lots of places like ebay, amazon or strip from any old piece of broken electrical item. It is not that difficult. You could also just shorten and rejoin the wire hence taking out the broken bit.

[@addersyou]

I have same problem, vac works for few seconds then goes off and charge light flashes. t have found that if I plug the vacuum back into charger for about 20 seconds or less then remove it, the vacuum works fully. I Suspect something more sinister. Has anyone else found this problem? I will strip down and investigate.

[@julieryles7461]

[@comeinhandynow]

Check the battery voltage....

[@lesrogers7310]

Yes, if the battery has been stored for a long time the voltage will be below minimum and charger will not recharge it. This is due to the protection circuit built into the battery,

[@mrjason9382]

Thanks for shareing

[@Chiefdog]

When I charge mine it just keeps flashing green on the charger.....is there a fix for this please? It’s a dyson dc44

[@comeinhandynow]

Maybe the battery is completely flat and is seen by the charger as shorted out. Look to buy another battery.

[@phweakwilled]

I am trying to ascertain if my DC34 Animal has a faulty charger or battery. I assumed as it had been left unused for a year it was the battery but there is no green light on charger. Tried a multimeter on outside and inside of barrel connector no voltage. If the charger was functioning ok would connecting a multimeter make the green light come on? Or would the volt meter be too high a resistance and thus not enough current would flow? Does this switch mode charger not supply full current until a load is detected?

[@comeinhandynow]

Ok, i just measured my charger plug (inside/outside plug) and it reads about 25v, not plugged into Dyson. So the voltage is always there. I assume the green light comes on when sufficient current starts to be drawn. The multimeter takes very little current so no green light. So it could be a broken cable, like my problem a while back. Try stripping some cable off the lead and measuring again. Otherwise a charger issue.

[@Imwright720]

Dyson wants $160 for a battery. This would be the 3rd one in 2 years.

[@atlanticsound3851]

You could try dismantling and measuring the battery voltage to see if they are actually charged up.

most folks would simply throw it away. Dyson won't repair it, and anyone else will tell you that it's cheaper to replace it. Considering that the battery pack is otherwise destined for the recycler, there's nothing wrong with this repair.

[@kidda74]

So to save a lot of ball ache just buy a new charger! ;)

[@comeinhandynow]

Finding the fault is the key. I thought that it was the battery at the start and just buying a new one of those would have been a waste of money and time, but in the end it just needed a bit of cable stripping off near the plug and a wire rejoining in order to fix it.

[@nancyalywahby2784]

[@comeinhandynow]

@@nancyalywahby2784 That is why finding the actual fault is key. You could try stripping it down and finding if the charge voltage is getting to the battery. Also maybe the battery has flattened too much and a new one is needed. If you are not ok with that then maybe look for a reconditioned one, they are cheaper if you find one.

[@comeinhandynow]

Is that all you have got to contribute? Nothing constructive. You obviously didn’t see what was actually required (fix to broken wire in charge cable). The rest was just for interest documenting how I tested and dismantled things to get to the bottom of the fault. It is not pretty trying to break into glued together parts that are not meant to be dismantled. Instead of just being a moaner why don’t you show me in your own video how it should be done? No? Thought not.
