SOURCE: Dyson DC07 works and cleans fine, but motor makes loud screaching sound.

If the screeching noise is happening at all times, it is most likely a motor failure; which unfortunately can only be resolved by complete replacement of the motor.
If it's a loud ratchety-screeching type sound, and is only occurring when the brush is set to carpet, it is most likely due to an obstruction of the brushroll or a problem with the clutch. Ensure that the brushroll can spin free, look for anything physically blocking it. Check the bearing ends on the brushroll, they can melt and cause the brushroll to not spin effectively. If neither of those two things resolves the problem, the clutch most likely needs replacement.

SOURCE: Dyson DC07 shuts down after 5-10 minutes of use and horrible suction!

I have had this problem on two dysons and have solved it by replacing the so called lifetime pre-filter. The problem is not the washable blue sponge but the material gauze filter in the plastic surround.

To see if this is your problem try removing the whole filter (i.e. the filter with the blue sponge inside - you need to remove both bits not just the sponge).

If you do a quick vacuum test for a few minutes then see what effect this has on the suction.

If you need a new part try somewhere like here (you'll need to chose for the right model) : http://www.espares.co.uk/part/dyson/dc07/p/1086/716/6/420625/875479/lifetime-pre-motor-dyson-.html

As I say this has fixed both of mine.

SOURCE: Dyson dc04 motor runs but has no suction.

I would make sure it is the motor first by isolating the sounds to just the motor. Take off the dirt cup, both filters, and belt, then run it and see if the sound is still there. If it is, you need a new motor. If it isn't, you need to look for a clog, or bad roller bearing.

To take the motor out first undo the wiring running down the backside of the unit inside of the switch housing. Then take the four screws out that hold the outer motor housing on, and the rest pops apart. Once you get inside, the gaskets make it a really tight fit, so you might have to hit the motor shaft with a rubber mallet to get it out and use penetrating oil on the bottom gasket to get the new motor to slide back in.

I guess there is no easy explanation. Let me know how it goes.

SOURCE: A Dyson dc 17 Animal and the wand/hose has lost suction

Hi its Darran at Dyson.

From your description of the problem, it sounds as though the wand/hose is blocked. To check this, remove the wand/hose assembly from the machine, switch it on and test the suction from the top of the wand with your hand. If the suction is poor, remove the wand from the hose and test the suction from the top of the hose. If its good here, then you know that the wand handle is blocked.

For the full diagnostics, check out the Support section on our website at www.dyson.com or call our Helpline on 1866MYDYSON.

Kind regards

I just cleaned out my Dyson animal, which had no suction. Now, all put back together, the suction is there but the machine makes a long lasting sound when I shut it off.


Hey, It's Jim with Crucial Vacuum,

If you're hearing an odd sound that is somewhat prolonged after you turn off your vacuum it be that your belt or brush roll needs replacing.

If you have suction and there aren't any clogs in your vacuum your belt might be worn and loose, which could give off an odd noise as it slows down along with the brush roll upon you turning off the vacuum.

Does your Dyson DC14's belt lack tension? It may be hitting the brush roll at the wrong angle. Same deal with the brush roll itself. Turn your vacuum over and take a look at the bristles. Are they loose or worn down? These are indications that its time to change these two parts of your Dyson DC14.

If these parts aren't in top shape or attached properly they're bound to make a number of odd noises.

We do offer low cost high quality replacement parts for Dyson DC14's. They can be found at the below link:

Machine shut off when suction release button was accidentally pushed. Now it won't come back on! What should I do?


Hi there, it's Jack at Dyson.

The issue you've described sounds very unusual. DC23 has a suction relief trigger underneath the hand grip of the wand handle, but this isn't connected to the vacuum's electrical components and shouldn't cause the vacuum to cut out in use.

However like most Dyson vacuums, DC23 is engineered to shut off for protection if it starts to overheat. This may occur if the machine is used when blocked, or if the filter is overdue for a wash. It should reset automatically after it's had around 2 hours to cool down, but to prevent it from happening again please follow the steps shown in our online support guide: http://www.dyson.co.uk/support/dc23/dc23-animal/my-machine-is-not-working/check-telescopic-wand-step-1-turbine-head

In normal use, we recommend washing the lifetime pre-filter at least once every 3 months using cold water without detergent. Allow at least 24 hours for the filter to dry completely before replacing it.

I'm confident following these steps will resolve the issue, but if you'd like further help or advice after giving this a try, please call our experts directly on 0800 298 0298 (UK), 1-866-693-9766 (US), 1-877-397-6622 (CA) or 1800 239 766 (AU).

Switching on and off no suction


Hi there, it's Jack at Dyson.

Like most Dyson vacuums, DC14 is engineered to shut off if it starts to overheat. This could be due to a blockage, and the filter may also need a wash.

In normal use we recommend washing DC14's pre-filter at least once every 3-6 months using cold water without detergent. Allow at least 12 hours for the filter to dry completely before replacing it.


To check for any blockages, follow each of the steps shown in our online support guide: http://www.dyson.co.uk/support/dc14/dc14-animal/my-machine-is-not-working/machine-not-sucking-picking-up-as-well-as-usual/how-to-wash-filters/wand-suction

Why does the suction stop after 10 minutes of use on my Dyson DC43?


Your vacuum may be overheating and shutting off the suction motor. Clean the cyclone assembly and the filters to see if they could be restricting the airflow.

Hi Lynette, it's Jack at Dyson.

I'm sorry to hear your DC31 seems to be working intermittently like this. To determine which part may be at fault we'd need to take you through some quick diagnostic checks over the phone when you have your machine to hand.

To speak with our experts directly you can reach the Dyson customer Helpline on 0800 298 0298 (UK), 1-866-693-9766 (US), or 1-877-397-6622 (CA).

Dyson DC17 Animal does not have enough suction from the wand handle to power the mini turbine head. The wand handle has very little suction.


Hi its Darran at Dyson.

It sounds as though your wand/hose assembly is blocked. Try following the blockage procedure in your user guide or visit our website's support section where you can use our self help guide to diagnose problems.

Hose is not getting any suction


when vacuums shut off randomly it usually means they are overheating. this can be caused by a clog somewhere in the line of suction, or, perhaps due to a very dirty filter - either way, the motor is working hard and getting too hot.

try removing all the various tubes and parts along the suction route and checking for clogs (a flashlight might help too). also, have you rinsed out your two pre-filters lately as recommended in the Dyson manual? it might help.
