Dyson DC45: Why does my Dyson stop working every 3-5 seconds

Sat, 23 May 2026 20:31:29 -0700

We have a Dyson DC45. It shuts off (stops working) every 3-5 seconds. Can this be fixed, by myself or at a repair centre?

The Dyson DC 45 ( I have shown DC56 here as it appears similar to the DC45) stops every 3-5 seconds when in use. The following is a more detailed series of the events which occur.

The Dyson is fully charged, when starting use with the brush head attachment, stops working after about 10 seconds of use.

We turn it on using the trigger starter. It stops again after about 3 seconds. We release the trigger and press it again. It starts and runs for approximately 3 seconds, then stops again. The sequence of restarting is repetitive until we give up in frustration.

Is there a "home fixable solution" or must it be taken to a repair shop? If so, where in the Toronto area can it be taken.

Thank you

Dyson DC14: Why doesn't the vacuum head lie flat anymore?

Mon, 18 May 2026 10:17:31 -0700

The head of my DC 14 doesn't lie flat anymore. I had it in for service to replace a starter switch last July. When I got it back, it was very stiff to push and seemed to have great suction. I heard a cracking noise then when I was trying to pull handle down to vacuum. Since then, the head doesn't lie flat.

Dyson v6 Absolute: 0V missing at the brush head motor

Mon, 18 May 2026 09:42:50 -0700

The brush head has stopped working. I have cleaned all the removable parts properly and put it back together. However it still fails to spin. The vacuum motor is working fine!

So, next I took the main body to pieces to reveal the PCB. Using my multimeter I found there was 21V across the vacuum motor terminals. But when I went across the brush head supply terminals I get nothing. However if I go on the positive terminal of the brush head and the negative of the vacuum motor I get 21V.

i’m aware that there is some sort of overload to protect the brush head motor in the case of drawing high currents, and im assuming it’s in the negative line, but where is it? And can I reset or replace?

Dyson V15 Detect: Dyson V15 Detect stops after a few seconds with no indicators

Sat, 09 May 2026 08:32:51 -0700

I've had it for nearly 2 years. The problem occurs when I press the trigger—it runs for a few seconds and then stops (with its signature "wooump" sound). It repeats this 2-3 times before eventually working. However, now I can't get it to run for longer than a few seconds, even after several tries.

I’ve changed the filter and cleaned everything I can access. In some forums, I’ve read that it might be an issue with the "main body," (whatever that means) while others suggest it could just be a cracked trigger, which should be an easy fix.

Dyson v8: Not working - 3 blue light on

Sat, 02 May 2026 19:14:30 -0700

Hi,

my Dyson v8 is not working. At first I thought it was a battery, but when I press the power button, the 3 blue lights come on (not just one - a weak battery indicator). But the cleaner doesn't work. Anyone know what the problem might be?

Thanks.

Dyson Vacuum: Wet Dog Smell from Dyson Vacuum

Tue, 28 Apr 2026 08:53:57 -0700

I accidentally got water into the cyclonic portion of my Dyson alergy. I let it dry from 4 days and now when I use it, it smells like wet dog hair. Is there anyway of removing this smell without replacing the cyclonic canister?

Hello, my Dyson v7 motorhead isn’t charging. After pressing the button to use it, the vacuum would flash a red light at the bottom for a short while before shutting off. The same happens upon plugging it in. Does anyone know what is going on, if so how do you fix it?

I need a replacement battery for a Dyson handheld stick vacuum identified as SV25. It may be an older model with the "star" type filter and a s/n starting with U1C. Your SV10 battery is supposedly not compatible. Thanks?

Dyson Ball Animal: Loud grinding noise from ball

Mon, 09 Mar 2026 15:55:33 -0700

This happened mid yesterday while vacuuming stairs (if that’s relevant)- so there’s a bit of jostling the vacuum around as I go up the steps. Halfway up, ball starts making a loud grinding noise that makes me afraid to run it. Let it cool down and it sounded even worse when starting back up. It’s not the whistling noise others describe and it isn’t just upon start and stop. Wondering if there’s something I can do before reaching out for professional repair.

Dyson Vacuum: Red lever will not pull up so I can empty/replace canister

Tue, 24 Feb 2026 15:35:26 -0700

I cannot empty my V8 canister because the red lever will not budge will I try to pull it up. Dyson is sending me a new canister, but have no idea how I can change it because you have to pull the red lever to release the current one.

Dyson V12 Detect Slim: V12 keeps shutting off in seconds, but…

Mon, 23 Feb 2026 11:51:20 -0700

V12 started shutting off after several seconds.

First, it only happened when the vacuum increased suction.

Then, it started happening within normal use. But if I started it in eco mode, it worked ok.

The thing is, once I turned it on again 3 or 4 times on a row, it started working as usual, without shutting off. Like if something is heating up so the vac starts operating as normal.

Now it shuts down even in eco mode. Still, 3–4 restarts help, and it runs until I manually turn it off.
