Dyson Vacuum Overheating/Cutting Off/Blowing Fuse

Dyson Vacuum Overheating/Cutting Off/Blowing Fuse

Dyson vacuums are great machines for cleaning your home, but due to their complexity, it can be very frustrating when they experience malfunctions. Some of these can include overheating, shutting off, or even the fuse blowing. What are the causes behind these issues and how do you fix them?

Your Dyson vacuum is overheating/cutting off/blowing fuse because the bag/canister is too full or there are blockages in your hoses, a dirty filter, or electrical problems in your home. If in doubt, contact Dyson or a qualified repair person about getting your machine fixed.

Being forced to play triage nurse to a vacuum can be annoying, but this article will help you diagnose some of the most common problems with your Dyson vacuum that you can spot and fix yourself.

Dyson Vacuum Keeps Overheating: Causes and How To Fix

Dyson Vacuum Keeps Overheating: Causes and How To Fix

Overheating is generally because something is blocked in the vacuum. To check this, make sure the vacuum canister or bag isn’t full, then remove your hoses and attachments to see if they’re blocked. This topic will be gone over in further detail in a section below.

Other causes of overheating are damaged parts and dirty filters, which we’ll be going over in detail later. Overheating generally isn’t a fatal problem, and can usually be fixed with due diligence.

Is the Vacuum Full?

It may sound too easy to be true, but the simplest cause for a Dyson vacuum to overheat or otherwise malfunction is when the bag or canister is full. When the container is too full, the vacuum can’t pick up any more matter. This causes the vacuum to jam in various hoses and the filter and can cause the vacuum to overheat and even shut down.

In extreme cases, if you simply forget or refuse to empty the bag or canister, it can result in the motor overheating and becoming damaged – even damaging other components in the vacuum, such as the fuse.

The best solution to this problem is simple prevention; always check how full your Dyson is after using it, and empty the bag or canister when it’s at least 3/4s full. If you develop a habit of making sure your vacuum isn’t bursting full, you can rest assured that this isn’t the culprit the next time you experience a problem.

Dirty Filter

Another place to look first after a malfunction is the vacuum filter. If the vacuum filter isn’t regularly taken out and cleaned, it can cause problems with the unit. This includes blockages in hoses, the motor, and problems sucking up matter. If the problem persists, it can lead to more extreme issues like the motor overheating and the vacuum even shutting off.

Ideally, the vacuum filter helps suck up harmful particulates such as dust, allergens, and other undesirable particles you don’t want floating around. When the filter gets too clogged, it can’t suck these up, and your problems begin.

To best prevent having problems that stem from a dirty filter, you should regularly check your vacuum filter. Every Dyson may be different, so it pays to check exactly how to remove the filter in your Dyson vacuum. Once it’s removed, you can soak the filter in water and ensure that there’s no dust or dirt clinging to the filter. After it’s clean, let it air dry and replace it.

Dyson Vacuum Cutting Off/Turning Off: Causes and How To Fix

Dyson Vacuum Cutting Off/Turning Off: Causes and How To Fix

When your Dyson cuts off randomly, there are a few places to start looking. Surprisingly, this is also linked to overheating. When your vacuum overheats, it will cut off in order to avoid damage to the motor and other internal parts of the system.

Other potential causes are electrical problems in the vacuum or your home where the Dyson is plugged in – this is typically easy to diagnose, and we’ll be going over this in greater detail in a section later.

If any part of your system becomes clogged with dust or even irregularly shaped items, it can reduce the airflow of your Dyson and cause problems. Specifically, if you have a blocked hose, then your motor will continue trying to suck in air and have to work harder due to nothing coming in. Since the motor isn’t made to work that hard, it can overheat and cause shutdowns and even damage.

If you experience overheating or shutdowns, check your attachments and hoses for any blockages that could be causing this. It could be as simple as a large hairball or wad of dust, or even a wayward children’s toy that made its way into your vacuum. Remove the offending object and try to start your vacuum again to make sure this was your problem.

Other than hoses, your attachments and brush bar can get clogged up too, causing the motor to overheat in its effort to keep the brush turning. If the brush stops turning as it should, immediately turn off the vacuum and turn it over to check the brush bar. If it’s blocked for any reason, take out whatever’s blocking it and try turning the vacuum on again.

Damaged Parts

After you’ve checked your vacuum to make sure that your problem isn’t because of the system being clogged or dirty, you should check to make sure you don’t have any damaged or faulty parts.

The main component to check in this case is the belts. If your belts have any cracks or breaks, it will cause the motor to malfunction, which can lead to overheating and even loss of power because of the fuse tripping or blowing.

I’m not saying that you should break down and check every component of your Dyson regularly, but when you experience a severe problem and rule out the system being clogged or dirty, looking for damage is the next logical step you should undertake.

Another thing to keep in mind is that belts wear down over time and need replacing in order to keep your system running like new. If you check your belts monthly, whether you have problems with the vacuum or not, you’ll keep your vacuum in tip-top condition.

Dyson Vacuum Blowing Fuse: Causes and How To Fix

Dyson Vacuum Blowing Fuse: Causes and How To Fix

When your Dyson blows its fuse, it can be alarming for a variety of reasons – naturally, you want your vacuum to remain in good condition, as well as avoid damage to electrical systems in your home. A Dyson vacuum blowing its fuse can be linked to overheating and the vacuum shutting off randomly, as well as electrical problems in your home. Also, if the fuse in your vacuum is faulty, it’s far more likely to blow.

It’s best to check to make sure you’re using the correct amperage fuse for your Dyson when it blows, and replace it with the correct fuse. Other places to check that we’ll be covering in later sections are dirty filters, damaged parts and seals, and home electrical problems.

Electrical Problems

Failing all of the above, a Dyson vacuum can experience a problem running when a particular outlet has an electrical problem or even a bad fuse in the vacuum. Thankfully, there are steps you can take to safely diagnose whether you have an electrical issue in your home or vacuum.

Firstly, unplug the vacuum from the outlet and plug in something else you know has no problems, like a lamp or phone charger with an indicator light. If the device doesn’t work, that outlet is your problem and should be checked by a qualified electrician.

If the outlet is fine, though, your problem is likely the fuse in your vacuum. You’ll need to find out with the help of your user’s manual how to locate and remove your fuse. Generally, Dyson vacuums take a 13 amp fuse that can be easily found and bought.

After you replace your fuse, try plugging your vacuum in and running it to discover if this has fixed your problem.

Maintaining Your Dyson Vacuum

Regular maintenance and cleaning of your Dyson vacuum can help reduce the chances that you ever see a problem, and overall increase the longevity of your vacuum. There are several easy steps you can take to give you peace of mind that you’re doing everything you can to keep your Dyson vacuum in great shape.

  • Regularly check filters
  • Check hoses, brush bars, and attachments for blockages
  • Check belts for cracks and damage
  • Replace belts as necessary
  • Replace blown fuses immediately

As you can see, it doesn’t take a trained professional to perform basic cleaning and maintenance procedures that can maximize the lifespan of your machine. Just methodically follow the steps, and you’re golden!
