20 Most Recent Dyson DC07 Bagless Upright Cyclonic Vacuum Questions & Answers


Many devices including this one have what's known as a thermal cut out.

It is there for obvious safety reasons and prevents the temperature in the locality of the cut out from exceeding a pre-defined value.
Some of them require you to press a reset button in order to switch the power back on and other types simply reconnect the electricity supply when the temperature returns to normal (safe) operating limits.
The Dyson DC07 has a thermal cut out located close to the motor and it is of the "self resetting" type.
If your vacuum cleaner switches off after a few minutes the most probable cause (there can be others) is the thermal cut out has operated.
The first and most important thing to do is to establish why it has operated.... If the airflow around the motor has become restricted then it will not be being sufficiently cooled and so it will have cut out correctly. However, thermal cut outs are often quite crude internally and it is not uncommon for them to start cutting out at too low a temperature. So...

Here's what to do...
(some tools may be required to complete the following so read the entire procedure before starting. Please note this is not an absolute guide if you need really foolproof step by step instructions... buy a manual! But this should help)
  • remove and thoroughly empty the dust bin (do not put it back yet)
  • remove and clean the drum filter to the right of the motor (right when looking at the front of the machine). (N.B. Never put this back if it is still damp)
  • remove the accessories from the upright section
  • withdraw the handle and separate it from the flexible hose (all of these and the following parts have a colored (commonly yellow) release tags/buttons/levers *** Never force anything!! ***
  • remove the flexible hose
  • remove the pipe union to the left of the motor
  • carefully lie the machine on its front (wheels uppermost) and remove the u-bend
Check all these parts for blockages/clogging before continuing...

There are now only two areas left that I know of which may cause further blockages. One is the "whole of life filter" located under the dust bin and the other one is inside each of those seven little cones (cyclonic chambers) at the top of the dust bin (root 8 cyclone is usually written on one of them). The following will require some tools and some common sense...
  • carefully prise the plastic disc up (the one under where the dust bin rests) use a flat bladed screwdriver or similar releasing it from the lug you can see at the front. Inspect the filter and replace if necessary (when replacing it you may find the original has been glued to the plastic lid - if so gently scrape it off )
  • If none of the above has revealed an obvious problem lets turn our attention to these pesky little cones... if you have ever vacuumed up any damp material these can become blocked. You will need a size 15 star drive (sometimes known as torx TX-15) screwdriver. I recommend you buy one with a shaft length of at least 70mm (you will need one this long if you are to access the thermal cut out later)
  • Place the bin assembly on a suitable dust sheet.. this can get messy!
  • remove the clear plastic outer bin
  • undo the three star drive screws at the top and partly withdraw the top ***careful*** you can not fully withdraw this piece. All we are doing here is creating a bit of limited access and "peer room" (before withdrawing the lid you may wish to peer underneath and for future reference note how the release rod is engaged).
  • now here you have to use a big dollop of care and common sense. By peering into these cones (shine a powerful torch through the sidewall of the cone) see if you can tell if any of them are blocked.
  • using a small piece of wire or similar gently poke any blockages away. Be careful not to damage the loose but still attached lid.
  • reassembly is a bit tricky because you have to re-engage the release rod at the bottom whilst at the same time pushing the lid back into position. Take care not to damage or trap the large rubber sealing ring as you press the lid home Finally replace the three screws being careful not to over tighten.
If none of this revealed anything very positive... Its time to open up and inspect the motor casing/thermal cut out.

**** WARNING**** The next section requires someone who is technically minded, has fiddly fingers patience and a basic understanding of typical plastic goods assembly techniques. As I am not including photo's the descriptions given can only be considered as pointers to how to do it (I'm not writing a Haynes manual here! So if you are a cak handed clot with little or no patience and a tendency to resort to ever bigger hammers - take the vacuum cleaner to an independent repair shop - explain the symptoms, tell them what you have done so far and leave it to them!!

  • In order to release the roller brush and belt mechanism turn the vacuum cleaner face down undo the three 1/4 turn screws and carefully withdraw the grey plastic cover (ease the belt guard section gently away)
  • coax the belt from the motor end then withdraw the belt and roller from its housing
  • Now we need to release the mains cable from the switch area to the motor housing - Undo the screw below the yellow switch
  • Working from the back prise the plastic housing forwards (this is tricky) leaving the switch in the on position can help but the main lugs stopping the housing from coming forwards are at the top just behind the big yellow switch button. the best way is to insert a fairly small flat bladed screwdriver in past the upper lugs at the back and put a slight outwards force on the housing tou are trying to remove... patience! Repeat for the other side
  • Now undo the electrical connections and release the flex from its channel so it is free to be withdrawn when you release the motor housing
  • turn the vacuum on to its front and remove the four torx drive motor housing securing screws (two of these are down a fairly deep recess)
  • carefully withdraw the complete motor assembly from the shell
  • The remaining part of the grey plastic casing can now be removed (a bit fiddly)
  • You should now have the complete motor assembly housed in a black plastic case with the grey intake at one end. Inspect this carefully and you will see that the grey intake is held in place with four lugs. gently prise the black plastic over these lugs and the grey intake will come away
  • Now you need to do two things in stages - pressing on the shiny metal motor shaft will push the motor out of the black casing but make sure that at the same time you feed the mains flex complete with rubber boot through the hole.
  • Voila the motor is now exposed
  • Inspect the motor for any signs of overheating or damage - check the brushes are OK (if you don't know what these are and you've got this far, now may be the time to ask a friend with a bit more knowhow to help!)
  • Unplug the electrical connections and undo the small Phillips screw holding the plastic assembly to the motor casing (this contains a capacitor and firmly pressed against the metal motor casing is the thermal cut out
  • If all else seems OK replace the thermal cut out with a new one and reassemble
  • No I'm not going to explain how to do that! For the most part just carefully reverse these instructions! - come on you've made it this far!!

NB. NEVER remove or bypass the cut out. this really could be very dangerous!

I hope this is of some help... Regards to all.

you may have a broken belt. Bad news regarding all Dyson's. You can't replace just the belt your self. You have to purchase a new belt assembly which includes the gears. And it wont be cheap. I would call it a design flaw but i am sure that dyson calls it a profit scheme.

Look carefully at the housing. Often there are buttons or clips you can loosen to allow the roller to be replaced and also give you access without removing the belt. Go online and search for your eureka model and look for a user guide or manual, which may also help. Good luck!

Hi there,

Some plush pile carpets are unsuitable for use with a vacuum cleaner equipped with a revolving brush. I'd recommend contacting the carpet manufacturer for advice on the correct way to clean it. They may suggest vacuuming it with the brushbar switched off - to do this, turn the brush control on your DC07 to the 'hard floors' setting.

If you have any further concerns, please get in touch with us directly - one of our experts will be happy to provide further assistance. You can call us free on 08002980298 (UK), or 1866MYDYSON (US).

You may need new belts. Belts lose elasticity from being stretched. The clutch must be removed and disassembled to change the belts. It's easier to replace the clutch. The belts will be tight and It's difficult without a special tool. While you have the brushroll out pull the shaft out of the center and clean hair and debris from it or replace brushroll if worn or frayed.

Hi.

I have repaired Dyson machines for years & have never come accross this.
The only way you will have trouble extending the hose is if there is a blockage at the bend where you hold the wand could be a coin which when switched on flips accross & blocks oppening.

Is it easy to slide wand from flexi hose with machine switched off ? You will need to remove wand from hose & push broom handle down to the bend & tap coin out.

It could be your motor, or it could be a short or bad part somewhere. Your local Dyson service facility can check it for you.

Hello, this is Ava with Think Crucial.

To fix any you vacuum problem, a proper maintenance will do the trick. Most of the time cleaning the filters, checking for blockages and clearing the passageways, and cleaning the brush roll assembly will resolve this. And if after doing maintenance it is still the same, that replacing the parts will most of the time make your vacuum work like brand new.

Hello, this is Ava with Think Crucial.

I don't think there is a reset button to any Dyson cleaners. However, yourDyson vacuum has a safety device which automatically shuts off if it begins to overheat. In cases like this, you may need to wash your filters and check for blockages. If your machine turns off on its own, unplug it and leave it for at least an hour to cool down. Before turning it back on, make sure that there are no blockages in the attachments and filters are washed.

Hello, this is Ava with Think Crucial.

There are a number of reasons why your Dyson cleaner is pulsating off and on. First, it can be due to a battery of the cleaner. Make sure that the power cable is properly plug to the power and seated properly from the unit while charging. If you find that the battery isn't charging at all, you may need to replace the battery. Second is to check the MAX button of your cleaner. If the button lights up and flashes when your Dyson keeps on pulsating, press and hold the power button and depress the MAX button to turn off the function. You may need to do it for a few times to get the hang of it. Third is to check for any blockages or clogs in the attachments. Look down through the tube and check to see if there are clogs on the sweeper end or if the roller is tangled up in fibers. Clean the roller brush are if it it's necessary. You may need to empty the dust bin of your unit as debris can build up in hard to reach places. Lastly, cleaning the filters may fix the pulsating of your cleaner. Remove the filter and rinse it with cold water and air dry it for 12 hours. Don't use detergent when washing your filters. If the pulsating doesn't go with the given quick fix, I suggest to contact Dyson for further assistance on this.

Maybe the level to carpet is too low or there is more then one belt and one is broke?

Hello, this is Ava with Think Crucial.

If the dust cup is too full, there is no space for the dirt to go when you are vacuuming. To fix this, remove the dust cup and empty the it. If your vacuum is still not picking up dirt after emptying the dust cup, there may be something blocking the airway. There are two places where you can check for a blockage: the dust cup air duct and the intake opening behind the brush roll. To check for a blockage in the dust cup air duct stand the vacuum upright and remove the dust cup. Now you can disconnect the super stretch hose and check for clogs in the air duct behind the dust cup. If that is not the case, to check for a clog near the roller brush lay the vacuum down. Next check the opening behind the brush roll for clogs. If there is debris, clean the opening with scissors, carefully cutting away any debris.

Uncleaned filters may also the reason why your vacuum has lost suction. To clean the foam and felt filters, remove the dust cup and pull out the two filters that are on the top of the motor base. Rinse the filters with lukewarm water until the water is running clear. Let the filters dry fully before putting them back into the vacuum. If your vacuum is still not picking up dirt, you may need to replace it.
Unfortunately, if none of the other solutions worked, your motor is going bad. Most of the time a new motor costs as much as the vacuum itself and it is not easy to replace the motor. It may be time for a new vacuum.

Hello, this is Ava with Think Crucial.

If your vacuum doesn't turn on, make sure that plug is fully inserted into a fully functional electronic outlet. If it still not turning on after verifying this, it could be that the power switch is malfuntioning. You may need to replace the power switch by opening up the handle of your vacuum. I suggest to refer to your manual on how to replace the power cord or contact Dyson for troubleshooting steps. 1-844-679-1647

Hello, this is Ava with Think Crucial.

There are a number of reasons why your brush roller has stopped moving. General maintenance to your vacuum is crucial and will help it work at peak performance.

First things first lets focus on the brush roller. Unplug the vacuum and turn it on its side. Look for any noticeable clumps of debris or hair strands that may be caught in the brush roller. Remove these obstructions, probably best to do so with a scissor if it's hair or long pieces of carpet fibers. After removing the debris try manually rotating the brush roller to uncover other hidden clogs. Another thing to take note of is the condition of the bristles on the roll itself. Are they loose or worn down? These are signs that your brush roller is in need of replacing.

While checking out your brush roll you might as well take a look at your vacuums belt. Your belt should be replaced about every three months. After regular usage, the belt will stretch out, lessening the tension on the brush roller. Lesser tension diminishes the brush roller's turn rate and speed. If the belt feels loose then it certainly is affecting your vacuums suction as well as your brush roll not moving at all.
