Dyson-Repair-Guide-101-How-to-Fix-the-Dyson-Vacuum-Cleaner

If you own a Dyson vacuum cleaner, you need to know how to repair it if things go wrong. Not only does it save you a lot of money replacing it when you might not need to; it saves a bit of time as well.

Knowing how to do it yourself brings a sense of pride and satisfaction, but also lets you understand more about the way your vacuum cleaner works.  

Feeling a little panicked already? No need. I’ve done all the hard work for you, gathering the most common issues and fixes so that you can get to know your vacuum in a stress-free setting.

Grab your toolbox, and let’s head out on another vacuum cleaner adventure.  

Dyson Vacuum Cleaner: Attachments 

Before we get into the repairs, the attachments are another important feature that I want to go through. It’s important to really know every feature of your vacuum cleaner, and that includes each of the attachments that come with it.  

How Do You Get the Dyson Wand Down? 

This is really simple, even though it can look a little confusing when you first go to use your Dyson vacuum cleaner. Here are the steps you need to take to get it down and start using it: 

  1. Lift the wand cap up, and then proceed to pull the wand from inside the handle until it locks into place. 
  2. Press the wand release button on the vacuum cleaner, and then remove the wand handle and hose from the machine. You will find that the hose stretches out with the wand.  
  3. When you are done and want to put it back, push the wand back inside the hose. Ensure that it is straight, press the wand release button, put it back into its original position, and then replace the wand cap. 

What are the Different Vacuum Attachments for?  

Here’s a rundown of each of the Dyson attachments and what they are used for when cleaning your home: 

  1. Mini soft dusting brush. This is for gentle dusting around the home, which is ideal for blinds, tables, banisters, and other such locations. 
  2. Tangle-free turbine tool. The counter-rotating heads mean that hair doesn’t get tangled up in this attachment. It’s made for pet hair removal on furniture, carpets, and pet bedding. 
  3. Flexi crevice tool. This extends and flexes into the most awkward gaps and corners. It’s great for getting between furniture and cleaning car interiors effortlessly. 
  4. Stubborn dirt brush. Made for hardwearing carpets and welcome mats, as well as high-traffic areas of your home. Really works the dirt out of your flooring. 
  5. Mattress tool. Designed for getting rid of allergens and debris on your mattress as well as general upholstery. Perfect for those with asthma and allergies. 
  6. Combination tool. This combines a standard crevice tool and a dusting brush together. The dusting head slides up and down as needed. Great for reaching corners as well as dusting delicate areas of the home. 
  7. Quick-release up-top adaptor. This twists and locks at different angles so that you can clean high up areas of your home effectively. 

Dyson Vacuum Cleaner: Repair 

Now that we have been through the basics with regards to the accessories and how they work, we can really focus on the repair side of things. Below, you will find all of the common issues and fixes for Dyson vacuum cleaners.  

How to Replace a Brush Bar  

If you have a newer Dyson vacuum cleaner, the process of removing and replacing the brush bar is exceptionally easy. All you need to do is follow these steps: 

  1. Unplug the machine and lay it down so that you can access the floorhead. 
  2. Grab a coin and then use it to twist the yellow cap on the side of the floorhead. This unlocks the brush bar. 
  3. Slide the old brush bar out, and replace it with the new one. Then, replace the yellow cap and lock it back in place using the coin. 

If you have an older model of Dyson, things are a little more complicated. However, this YouTube video I found explains the process in a really quick and easy manner.  

How Do You Take Apart a Dyson Vacuum Cleaner?  

Taking your vacuum cleaner apart is not a task to be taken lightly, and you should always take the time to ensure you know exactly what you are doing. 

Of course, taking your Dyson apart does depend on the model, and so the best place to find out more information about the steps to take would be the official Dyson website: www.dyson.com/support 

However, it is also helpful to at least have an idea of what to do when you need to take everything apart, and the video I have sourced below demonstrates dismantling a Dyson V6 and V8. So, if you have one of these models you might find that you only need to watch the video.  

How to Change a Power Cord on a Dyson Cleaner 

Frayed and damaged cords can cause some serious issues when you want to clean your home, and knowing how to replace them is an excellent skill to have. It’s not too difficult, and it will take you less than half an hour to do, but following the instructions below closely is a must.  

  1. Make sure your vacuum cleaner is unplugged and stood upright. The, remove the dust canister and the wand. Behind where the wand sits, you will notice two Torx screws that are securing the switch to the vacuum cover. Remove these. 
  2. Push outwards on the two plastic clips that are securing the switch cover to the vacuum. Make sure to do this carefully to avoid potentially damaging them. Then, remove the switch cover from the vacuum cleaner. 
  3. Locate the two wires from the power switch and hold them firmly by their plastic coverings. Pull them from the terminal firmly. Do not pull from the wires, as this could damage them. 
  4. Locate the terminal below the power switch and remove it; this is for the power cord. You will then see the remaining wire of the power cord coming from the internal power cable. Hold the connectors, and work to separate them carefully. 
  5. Make sure the cables are connected, and follow these instructions in reverse to get it all back together again. 

How to Replace the Hose on a Dyson  

The hose is actually one of the most common parts that are replaced, mostly because it is more susceptible to cracks, general wear and tear, and rough handling. Removing the hose and putting a new one on is actually really simple, and it practically slides off the machine.  

However, to help give you a better idea of what to do, here is a great YouTube video that I sourced for you. The process literally takes less than a minute, and you’ll be ready to get going again.

As for where to get a new hose, the Dyson website is a great way to locate official suppliers for Dyson parts.  

How to Fix Loss of Suction on a Dyson  

There are a few common causes for a loss of suction, and it’s something I look at extensively in my other Dyson 101 guide. The main causes are as follows: 

  • Dirty filters that need to be cleaned and/or replaced  
  • Blockages in the hoses or floorhead  
  • Clogged brush bar  
  • A slipped belt on the brush bar 

The video that I have sourced below takes you through each of these potential issues, showing you where to find them and how to take your vacuum cleaner apart. It’s a great visual guide for fixing suction loss quickly and without hassle.  

How to Replace a Belt on a Dyson  

The process can vary slightly according to the model of Dyson that you have, and this is why checking the Dyson support website is often a good idea if you want to ensure that you are doing everything correctly.

However, here are the basic steps for belt replacement so that you at least have a clear idea of what you are supposed to be doing. 

  1. Turn off the power and unplug the vacuum cleaner. Then, lay it down and unscrew the soleplate so that the floorhead is completely open. 
  2. If the machine has just been on, leave it to cool down for a moment before inspecting the belt. Then, check that the metal spindle is clean before you loop the belt over it. Remove the brush bar from the vacuum. 
  3. Next, you can loop the belt onto the brush bar, making sure that it is attached to the spindle while you do so.
    Pull the belt until it is taut, and then snap the brush bar back into place in the machine. Rotate both ends of the brush bar back towards the machine until they will no longer do so. 
  4. Rotate the brush bar by hand to centralise the belt. Once this is done, you can replace the soleplate and screw it back in. Plug the machine in, and test it out to make sure it is working. If the brush bar is not rotating, the belt is not correctly attached. 

How to Replace a Dyson Filter 

While most Dyson filters are washable, there are times when they are going to need to be removed and replaced. 

You can buy Dyson brand filters quite easily directly from them or their licensed resellers, and as they don’t need to be replaced very often, it doesn’t work out to be too expensive. 

Generally speaking, you will find the main filter is in the top of the dust canister. This is easy to access, and all you need to do is slide it out.

This one is conical in shape, and is also the one that is least likely to need replacing. The HEPA filter is found near the motor, which varies according to the type of vacuum cleaner you are using.  

Replacing them is easy, it’s the same as sliding them back in when you have finished cleaning them; only this time the filter is brand new.

If you have an older model of Dyson, however, it can be a little tricky to change the filters as the process is much different – and these filters sometimes do need to be replaced. 

So, I have sourced a video (which you will find below) to outline this process for you.  

How to Use a Dyson Hose  

Upright Dyson vacuums are quite different from the cylinder models; especially when it comes to the hose. If you want to use a cylinder hose, it’s as simple as removing the wand, and you’re there, but upright ones are a little more complex (but not much).

Here are the steps you need to take to access the wand: 

  1. Lift up the wand cap found by the handle, and pull the wand up until it locks into place.  
  2. Press the wand release button on the vacuum cleaner, and remove both the wand handle and hose from the machine.
    You will find that the hose stretches out with it, and the wand can be detached if necessary. 
  3. To get the wand and hose back into their original positions, just reverse these steps and ensure everything is locked back into place. 

I understand how important visual aids can be, so here is another video. This time, it outlines how to use an upright Dyson vacuum cleaner, which is great for getting to know your model before you start handling it: 

How to Remove Hose from Dyson Ball 

Hoses get damaged, and they break; it’s a common issue for most vacuum cleaners. My last one needed to be replaced because my dog decided it was an intruder. 

They aren’t particularly expensive to replace, but the best part is how quickly you can get the job done. It only takes a minute, and the steps are so simple.  

Above, you’ll see a quick video that perfectly demonstrates the removal and replacement process. However, here is a quick rundown of each of the steps so that you have a good idea of what to do: 

  • Switch the machine off an unplug it  
  • Remove the dust canister from the main body and the wand from the hose 
  • Click the switch behind the dust canister to release the bottom of the hose  
  • Align the new hose with the tabs at the base of the machine and click it into place  
  • Put the canister back and attach the new hose to the wand  
  • Remember to dispose of your old hose safely and according to your local laws  

Here's a good read on Why Choose Dyson Brand.

What if my Dyson Loses Suction?  

There are a few common reasons why a Dyson vacuum cleaner may end up losing suction, and I have outlined each of the causes below with a little more information: 

  • The filters are clogged. This is such a common issue, and one that many of us forget about. If you have lost suction, or it is weak, remove both the standard and HEPA filter and give them both a good rinse under running water (no soap). 

    Once they have been washed, leave them to dry for at least 24 hours and make sure there is no trace of liquid on them before you put them back in the machine.   
  • There is a blockage in the hose or head. Check the hose and the wand for blockages, and slide a long object into them to remove debris or loosen it.

    You can also check the air passage in the main head for an obstruction (usually a sock). This does require removing the soleplate, but it is a very quick and easy process.  
  • There is a blockage in the brush bar. Flip the machine over and take a look at the brush bar. If it is tangled up with loads of hair, grab a pair of scissors and gently cut it off so that it can move freely again.

    You should also check the bar for larger debris, like clumps of dirt, and remove them by hand so that things get moving again.  

How Do You Troubleshoot a Dyson Vacuum?  

A troubleshooting guide is all about taking you through the most common issues people have with their Dyson vacuum cleaners. That’s exactly what I am about to do. Here are the most frequent problems, as well as the solutions you can try to get things working again.  

1. Loss of suction. I have been through this briefly a few times here, but it’s good to go through a rundown to make sure that everything is clear. Here’s what to do when the suction is lacking:

  • Clean the filters 
  • Check the floorhead for blockages  
  • Check the airway in the head for blockages  
  • Check the base under the bin for blockages 
  • Check the brush bar for blockages  
  • Check the hose for blockages  

2. Dyson won’t turn on. Pressing the power button to no avail, even when it is plugged in or fully charged? It’s probably overheated. This is what could be wrong and need fixing: 

  • Clean the filters  
  • Unplug it to cool down 
  • Check for blockages  
  • Check the seals  
  • Replace the battery in cordless models  
  • Check the fuse in the plug  
  • Check the cord to see if it is frayed or damaged 

3. The brush bar stopped spinningThis is a really common issue, and it has been touched on a few times here.

All you need to do is flip the machine over, pick up a pair of scissors, and gently cut any tangled hair and fibres off the brush bar. You can also check for any slid debris that has become wedged, but it is more likely to be hair.  

4. The locking mechanism is too weak to hold the vacuum up. This does happen more often than you might think, and I have had issues with it in the past. These steps are perfect for getting it back to fully functioning:

  • Turn the power off and tilt the machine back so that it is at a 45-degree angle
  • While holding the section under the airway inspection pipe (right-side of the vacuum), hold down the black forward lock button. Then, pivot this section upwards until it clicks into place. Once this is done, you can release the black button. 
  • Tilt the vacuum forward, and it should all snap into place and stand upright again. If you are still having issues, contact Dyson for further assistance.

How Do I Lower My Dyson Vacuum? 

Lowering your Dyson vacuum takes the same steps as generally adjusting the level, as this refers to the different floor types and the adjustments needed for the vacuum to be used on them.

Either way, the lowering (or adjustment) process is very simple, and all you need to do is follow these steps: 

  1. Stand behind the vacuum cleaner as you would when you go to use it, and then press the power button so that it is turned on.   
  2. Now, place one foot on either side of the vacuum cleaner head (your choice) and pull the handle towards you as you do so. This tilts the main body back, and you will find that the ball moves with it.  
  3. When you are ready, look for the level adjustment switch. This is usually found on the floorhead, but it depends on your vacuum cleaner. Move the slider to your desired position, depending on the floor type, and it will rise or lower accordingly.  

How Do You Retract a Dyson Handle?  

This is the same as releasing the wand, and the steps are the same as the previous section on the topic. To refresh your memory, here is a quick reminder: 

  • Lift the wand cap, and pull the actual wand until it locks in place.
  • Press the wand release button and pull the wand handle and hose from the machine.  
  • When you are done, reverse these steps and put it all back together. 

What if your handle gets stuck though? I have a great video from Dyson that can show you exactly what to do when it doesn’t seem to be releasing.  


How Do I Empty My Dyson Upright Hoover?  

When you have finished cleaning your home, you will need to empty the bin. How do you do it? Well, all you need to do is follow the simple steps below, and you’ll find that the whole process is easier than you imagined. Here are the steps you should follow:  

  1. Press the button on the top of the carry handle to release the bin from the main body of the vacuum cleaner. 
  2. Take it over to the bin and, while holding it over the bin, press the release button and allow the contents to fall out. 
  3. Give the canister a little shake, or a tap, to ensure all of the dust has fallen out. Then, snap the lid closed and place it back on the main body of the vacuum cleaner. 

Just remember this key piece of information; never allow the debris in the canister to go above the MAX line, as this can cause issues like clogging and a loss of suction. It may even cause the vacuum cleaner to break down.  

How to Replace Belt on Dyson Animal 

When you change the belt on a Dyson Animal, it is very similar to the process that I went through a few sections ago in this guide. Of course, every Animal model is different, and so you should always refer to the official Dyson website for specific instructions for your exact vacuum cleaner.

However, I do have a YouTube video for changing the belt on a Dyson Animal DC17 to give you a good idea of what the process entails  

Do Dyson Filters Need to be Replaced?  

All filters start to become worn down over time. There are conflicting views on how long a Dyson filter lasts before it starts to become less effective and needs to be replaced. Dyson filters are washable, so they tend to last much longer than standard ones.

Technically, the filters on a Dyson vacuum cleaner don’t need to be replaced, but it is a good practice for efficiency.  

Can You Wash a Dyson HEPA Filter?  

Yes, you absolutely can. This is the recommended way to maintain your filters and keep the vacuum cleaner running smoothly. All you need to do is remove the filters and wash them under running water in your kitchen or bathroom sink.

Once they are clean and free from debris, you can leave them to dry on the side. They should be left for at least a day, and they must be completely dry before being put back in the machine.  

There are some who suggest using soap to wash your filters. This is a practice I strongly disagree with. It can impair the filter’s ability to collect dust, and even encourage mildew to grow.

Even Dyson state they should be cleaned with plain water. The main filter in the dust canister should be washed monthly. The HEPA filter should be washed every six months, but checked monthly.  

When Should I Change my HEPA Filter?  

Word on the street is that the best time period for replacing a HEPA filter in your vacuum cleaner is every three or four years. For the conical filter in the top, you can leave it even longer – surpassing five years if you really want to. 

Of course, remember that only the much older Dyson vacuum cleaners are the ones that tend to need their filters replaced. The new ones are often fine with regular washing.  

You may also check out the How to Clean Dyson Vacuum for further information.

How Do You Take the Filter Out of a Dyson?  

The main filter is found in the top of the dust canister on every Dyson vacuum cleaner; corded or cordless. All you need to do is open the compartment and slide the filter out.

This is the conical shaped filter that acts as your everyday net for dust. All you need to do after that is wash it carefully as per the instructions a little further up.  

The HEPA filter is located near the motor on your vacuum cleaner. For the upright models, you will find that it is in the actual ball, and you will see that the motor is underneath the filter.

However, you should refer to your user manual or the Dyson website for your model of vacuum cleaner to ensure that you have the right location.  

To Conclude

Hopefully, this has answered a lot of your questions about Dyson vacuum cleaners and the way they work. It’s not always an easy topic to learn about, but it really is worth it when you come across an issue with your vacuum. 

If you still have more questions, however, I also have another handy Dyson 101 guide that covers a whole load of FAQs and issues. It’s certainly worth checking it out if you want to learn more.
