Dyson DC33 Troubleshooting Common Issues

The upright model of Dyson, The Dyson DC33 marked its launch date in the year 2010. Being lightweight, Dyson DC33 doesn’t compromise on performance or durability. 

However, The Dyson DC33 faces some common issues, related to suction, brush bar, etc. In this article, I’ll be showing you Dyson DC33 troubleshooting methods.

Dyson DC33 – Brush not Spinning

Dust Buildup or Hair Entanglements

One of the main reasons is that the brush bar isn’t spinning on your Dyson DC33, should be attributed to a dust buildup, or hair entanglement. 

You can fix this issue by disassembling your vacuum cleaner’s roller bar compartment and thoroughly cleaning any dust, debris, or hair entanglements that you find.

Safety Mechanism of Dyson DC 33

Your Dyson DC33 comes with a safety mechanism. What it does is that it shuts down the brush bar if there’s a dust buildup. Another possibility for brush to stop from spinning is that Dyson DC 33 motor is equipped with a thermal cutout sensor, it shut downs the machine to save it from any potential damage.

Dyson DC33 don’t have a reset button. It will automatically start working after motor cools down, it takes 3 hour approximately.

To get rid of this, you’ll have to disengage the roller bar from its compartment and thoroughly clear out any dust or hair entanglements you spot. You can do this by washing both filters in cold water without using any detergent. 

Height Adjustment

Unsuitable height adjustment can also cause your Dyson’s roller bar to not spin. Dyson DC33 models contain a specific height adjustment, for particular surfaces.

This means that if you’re cleaning multiple surfaces, you’ll have to readjust the height of your Dyson DC33, according to that of the surface.


Dyson DC33 – Brush Bar Reset Button

Although Dyson vacuum cleaners don’t come with a controller-type reset button, it’s still easier to locate and access.

If your Dyson DC33 roller bar stops spinning, then it’s a possible case of dust buildup or hair entanglements in the brush bar, preventing it from spinning efficiently.

In this case, you’ll have to disassemble your Dyson DC33 and remove the brush bar for thorough cleaning.

After you have done cleaning, you’ll have to press the reset brush bar button on your vacuum cleaner – commonly known as the on/off brush bar button.

Commonly, this on/off button is spotted on the top of your vacuum cleaner’s body or in a slit at the verge of your Dyson’s head.

DysonDC33 – No Suction 

The loss of suction on your Dyson DC33 can be quite frustrating, and there are numerous reasons too, as to why this happens.

Keep reading below to gain some insight regarding this issue and how to troubleshoot it.


After you’ve read the guide, and if you’re looking to proceed further, do disconnect the power supply of your Dyson DC33 for safety purposes. 

Dyson DC33 – Loss of Suction from Filters

Initially, you’ll be facing a loss of suction from your vacuum cleaner’s filters. Your Dyson DC33 typically comes with two filters, a pre-motor and a post-motor filter.

The task of both these filters, as you might know, is to trap any dust, allergen, or debris that it may find so that the particles don’t disrupt the normal functioning of the internal components.


However, if you’ve not been maintaining your vacuum cleaner, then there might be chances of a dust buildup, which will eventually make the task of trapping dust harder for your Dyson filters.


The most logical way to get rid of this problem is to clear out any dust, debris, or microscopic particles attached to your vacuum cleaner’s filters.

If filters are pretty much dirty and you feel like they are needed to be replaced you can check that from here. 

To do so, follow the steps below. There are separate steps for both Pre-motor and Post-motor filters respectively.

How To Fix Loss of Suction In Dyson DC 33

Pre-Motor Filter

To clear this filter, you’ll first have to click on the catch located below your appliance. After you have done, the filter will pop out automatically.

Now, this filter comes with two parts, namely a sponge, and a case.

Both of these components should be cleaned under cold water, to remove dirt particles. For the sponge, make sure to squeeze it a few times, to eliminate the excess dirt trapped in it.

Coming to the case, make sure to tap on its edges with optimum force to dislodge the dirt particles, this would make cleaning relatively easier and efficient.

Now, after you’ve thoroughly cleaned the dirt out of both the components, let them dry. It is crucial that both these components are fully dry, or else, the water from them can flow into the internal circuitry, disrupting your machine’s normal working.

Supposedly, if there’s still a handful of dirt left, you can always replace both parts.

Post-Motor Filters

The post-motor filter’s location depends on the type of Dyson vacuum cleaner you have.

For instance, if you own a bag less vacuum cleaner, then the post-motor filter will be present below the cylindrical container.

Coming to your Dyson DC33, to access the filter, you’ll have to snap the latch, and pull the lid upwards. Now you have complete access to the post-motor filter of your Dyson vacuum.

To clear out dust or debris trapped in this filter, you’ll have to follow the same steps as for the pre-motor filter, and voila! You have done.

Be sure to let this filter dry off completely as well.

However, if there’s still dirt left after a thorough cleaning, replacement of the filter would be a good idea.

Dyson DC33 – Loss of Suction from Hose

If you’re still facing issues after you’ve done cleaning both filters, then there may be possible blockages present in your Dyson DC33 model’s hose.

To access the hose, you’ll have to click on the catch present at the top of your electrical appliance. This would cause your Dyson’s wand to lift away. 

Now, look for a button present at the back of your Dyson’s wand. Pressing it would disconnect the wand from the hose.

Now, trace the origin from where the hose starts on your vacuum cleaner, you’ll be finding a button there. Pressing this button would allow you to disconnect the hose from the vacuum cleaner.

After you’ve disconnected the hose, make sure to check any tears present along the hose as they can cause serious damage to the hose, disabling the suction on your vacuum cleaner.

Once you’re done checking for possible blockages or tears in the main hose, then take a look at the internal hose that can be accessed on the front of your vacuum cleaner.

As for the main hose, look for any possible blockages or tears in the internal hose as well. If you find any such issue present in either hose, the most effective solution would be to replace it with a new one.

Take a look for any sort of blockages caused in the ducting as well. Once you’ve removed the pieces of your vacuum cleaner’s ducting, take a look inside it for any blockages present.

Also you might see a Dyson blockage light but there’s a possibility that there is no blockage. For the moment I won’t expand on the details here. You can probe that thoroughly by reading this. Dyson Blockage Light But No Blockage.

Dyson DC33 – Belt and Brush Roll

A belt doesn’t directly affect the suction power of your Dyson DC33 but creates more of a misconception.

Damage to the belt can cause your Dyson vacuum cleaner’s brush bar to stop working properly. It can  leading you to think that the suction power is the main cause of the problem.

So, if you’ve checked the filters, hose, ducting, and belt properly, and still face an issue, then the most probable cause of your problem would be the motor.

In this case, should be replaced with a new one, for proper function.

Is Dyson DC33 Discontinued?

Yes, the Dyson DC33 model has been discontinued as of 2013.

Is Dyson DC33 Discontinued

Dyson DC33 models replicate some of the functions of DC04, DC07, and DC14 in them. For instance, the usage of a single motor for suction. 

In 2013, Dyson broke the bad news to many of its users that the Dyson DC33 model has been discontinued. There hasn’t been any news of a replacement model ever since.

However, Dyson has launched a new line of vacuum cleaners that are more powerful, efficient, and better in every way.

Dyson DC33 – How to Use Hose

To detach the wand from the vacuum cleaner, you’ll find a button located behind the power switch of your Dyson DC33. Pressing that button detaches the wand from the vacuum cleaner.

Dyson DC33 comes with “mini brushes” to clear specific surfaces efficiently. These brushes should be attached to the hollow end of the wand. 

To detach the “mini brush”, you can click on the button located at the hollow end of the wand. 

You can also readjust the height of the wand, to clean particular surfaces. To do so, you’ll have to reattach the wand with the vacuum cleaner and press the red button located at the back.


Although Dyson DC33 had lived up to its promise, it still contained a few common issues.
