What's wrong with my Dyson handheld (blue flashing light)

Battery has had it, mine did the same, bought one from ebay (not a dyson branded battery) and it's sorted the issue and now actually lasts a useful amount of time again.

yup same ^^^

Have you got a compressor? out into the garden, remove the filter, release the dust collection basket thingy and blow it all out thoroughly (not near the washing 😀 )

Good as new, we do this to ours once every 18 months or so for of the same issue.

Or the battery is knackered 🙁

+1 for the battery if you've done the filter cleaning regime. If it's still under warrantee, (2 years) Dyson will send you a new one FOC. Actually replaced ours on Wednesday evening for exactly the same reasons/symptoms.

I don't think it is the battery as we got that replaced under warranty (ie, with an original Dyson one) last year and if I plug it in for a couple of minutes it then works fine usually.

Edit: it was two years ago (sheesh). Maybe it is?

If it's a V8/10 etc try a new filter, they sometimes get so clogged that even washing doesn't sort it, well that what happens in my experience.

Try holding down the filter and see if it still happens. There's a loss of suction thing that we had on ours that cut it out. The other thing was the brush head not spinning and clogged with hair that also led to it cutting out and the blue fishing light.

Not sure if that helps! I'm still nursing our old one along!

The fact it works when battery is freshly charged obviously points at degraded battery to me?

I know you say you have cleaned it but mine does that when the filter is getting blocked, easiest way of checking is to run it for a few seconds with the filter out. If that doesn't work, it sounds battery related.

Ours is a v7 and it's over 4 years old now on its original battery, it just gets clogged up in the internal workings, compressor sorts it out every time. I do the same to our old DC05 and that's still going strong.

+1 for the filter, ours is a V7.

I wrongly assumed it was the battery on ours too, replaced it, no fix.

Ended up replacing the filter and throughly blowing the whole lot out, fixed it. Now part of scheduled maintenance! 😀

Hmmm, I will try the 'filter out' suggestion - see if that works. However some tutorials show the 'cyclone' bits being taken apart and cleaned - it wouldn't surprise me if some of those are clogged up as it gets used for some pretty hefty cleaning duties (cleaning up sawdust from the hamster cage could easily block those I reckon).

filter blocked, cyclone blocked or battery fubared
The original battery is rubbish - I replaced it with an ersatz but bigger amp one, it has been great

We had our battery replaced by Dyson, and it was fine until that one died! did all the filter cleaning things and then bought a new (non Dyson) battery off Ebay/Amazon and its been fine for a couple of years now!

Its went full tory, only option is to nuke from orbit

Worth brushing the outside of the fine mesh bit above the collection bin then give it a lot of taps onto the bit where tools connect. I'm currently on a Whatsapp diagnostic conversation regarding my V10 not filling the collection bin evenly, hence it needing emptying more often.

Ours has been a total and utter bag o' shiiite. The battery perpetually loses contact with... the contacts. Just a shiiit design. 2x warranty batteries. The battery itself is not the problem but the design of how it fails to keep the contacts in contact with weight of the battery and any leverage it has from its weight.

Eventually went and bought a Bosch because the Dyson was so utterly frustrating. That's been faultless.

It was the filter with ours. Cleaning it didn't really work for us, but we got 3 for £10 from Amazon for generic, put in new filter, works fine

Yeah I just bought some earlier (2 for £8) - I guess it's worth a punt at that price.

I'm trying not to spend money uneccesarily - I am hoping it is fixable. And I just looked at the top of the range Dyson handheld and is now >£600 WTF not a chance.

Have you phoned the contact centre?

The owner is total c**t but he guys on the end of the phone are a good bunch and will sort you out.

Can anyone recommend a decent replacement battery brand that won't explode or burn down the house.

Not really, there's no guarantees that wont happen with the OEM batteries (for anything using rechargeable batteries) so all bets are off with cheap copies. There's a reason why just about all instructions with anything rechargeable tell you not to charge equipment unattended.

What @mrmoofo said.

Check the battery is charging when it is in the cradle. Crud can cover the contacts stopping charging.

Use a new filter. If you have ever sucked up plaster dust then that filter is it coming back. It is as gold dust to cyber men.

Check the WHOLE airflow route. The narrow apertures in the handheld (all Dysons) make for fast airflow and the ability to choke the thing on small bits of cardboard, feathers, or stones. I imagine many Dysons are disparaged or discarded because of clogging. It is a pretty poor weakness though: vacuum cleaner inoperable due to…small feather.

If charging, filter replacement, and airflow are not the problem then you need a new battery.

🤷🏻‍♂️ our V7 still does the whole upstairs after many years. Maybe I’m just not through enough?

What's wrong with it, it's a Dyson. Ours was useless, even with a replacement battery. Got a Shark early this year with two batteries, been brilliant in comparison. Only issue so far has been the wand wouldn't unlock, quick call to Shark, no worries we will replace it. Sorry no wands in stock we will send you a brand new unit. Less than a week from ringing, returning our old one and getting a replacement delivered.

Customer service is excellent and they work so much better on every level than the Dysons.

Yep, can't remember the exact problem with ours, something similar tho. Phoned dyson, they diagnosed that the main body needed replaced, and sent one out free. Warranty had never been registered and we'd had it about 3 years. Had to pay for a battery when it died a year later tho.

Don't use a Dyson anywhere near a stove. The ash bungs it pdq. We've had fantastic service from our V6. New body on literally the day the warranty ran out as it was getting loose (which may have had something to do with the kids dropping it). New battery as well after 3 years. It is seemingly getting easier to block these days, and I'm wondering about a v10 or something. So much easier to deploy than the Miele.

I have given my Vax the best clean it has ever had in 6 years with compressed air. Easy enough to dismantle the cyclone array with a cross point screwdriver which helped.
Gave the filters a good blast as well.
