The hair dryer is a must in many bathrooms. And when it is used daily, the purchase of a top-of-the-range hair dryer is then almost obligatory as a guarantee of performance and reliability. So when the lights on your Dyson Supersonic flash red and the device no longer works properly, it's a disaster. Very often, the breakdown simply comes from the filter which is clogged. It is therefore easily repairable on your own. However, sometimes it is also a sign that an internal component is faulty. In this case, outside help will certainly be desirable. Without further ado, discover what to do when your Dyson Supersonic flashes red?
Dyson Supersonic hair dryer flashing red: clean the filter
When your Dyson Supersonic flashes red, the good news is that most of the time it signals that the filter is too dirty for the device to work properly. And this failure is very easily repairable on your own.
The air filter prevents dust, lint, animal hair and hair present in the air from entering the engine; which could eventually cause a major failure such as a overheated and a melting of the engine or other heat-sensitive component. When the filter is too dirty, a sensor installed by the manufacturer detects it and then cuts the voltage of the device to avoid any risk. This is then signaled to you by the flashing of the red LEDs.
It is therefore important to clean it regularly to both avoid a drop in performance of the Supersonic hair dryer, but also to prevent it from automatically cutting off as you are currently experiencing.
To clean the filter of your Dyson Supersonic whose lights are flashing red, here's how to do it:
- Turn off the power to the Dyson Supersonic by unplugging it from the electrical outlet
- Wait a few minutes for the device to cool down
- At the base of the handle of your hair dryer is a grid. Remove it by turning it slightly counterclockwise. Slide it to the power cord, then open it in half at its notch in a delicate way.
- The air filter is located below the filter grille. Remove dust, lint and other dirt. Depending on how dirty the filter is, use either your hand or a dry, soft, lint-free cloth or a clean, soft-bristled toothbrush. Caution, never apply liquid or detergent directly to the air filter.
- If the filter grid is dirty, also remember to clean it by running it under running water. Then, let it dry and use a dry cloth or a soft-bristled toothbrush to remove the last dirt.
- Finish by putting the filter grid back in place, checking that it is correctly clipped onto the handle of your Supersonic hair dryer and that it cannot move.

Following this cleaning, the lights on your Dyson Supersonic should no longer flash red, and the device should work as usual again. If not, repeat the procedure. If it still doesn't work, then the problem is most likely a hardware failure.
Dyson Supersonic that keeps flashing red: replace a component
Unfortunately, if after cleaning the filter, your Dyson Supersonic continues to flash red, the problem is most likely due to a failure of an internal component. In this case, you will most certainly need to contact Dyson after-sales service or a professional repairer for a repair of the product. If you have strong electrical skills, you can attempt to disassemble the hair dryer to access the components, test them, and replace the faulty one.
Contact Dyson support or a repairer
When lights on your Dyson Supersonic are flashing red, the problem can also come from a defective internal component. This is due to natural wear, overheating, shock, or even, in rarer cases, a manufacturing defect.
If your Supersonic hair dryer is still eligible for a guarantee (compulsory manufacturer's warranty of 2 years in France, or more if you have taken out an extended warranty), call the Dyson after-sales service. You will then obtain the repair or exchange of your Dyson product free of charge.
If unfortunately your hair dryer is no longer under warranty, we advise you first to contact the Dyson after-sales service to make sure it is not a manufacturing defect. If this is not the case, take the opportunity to request an estimate of the cost of the repair. Then, we advise you to contact a independent professional repairer near you to request a quote and compare prices.
Check the components of the Dyson Supersonic flashing red
Si you have solid electrical clearances, you can also try disassemble the device to test its internal components and try to find out why your Supersonic Dyson is flashing red.
You have been warned! : - the dismantling of the hair dryer makes you lose the rights to the guarantee. - spare parts are often not available for sale to individuals. - Risk of electrocution and cuts. Wear insulated gloves. - Risk of irreversible damage to the device. Do not carry out the manipulations if you are not competent to disassemble, measure, solder, reassemble the electrical components.
The main components to test in case of failure on a Supersonic Dyso hair dryern are:
- Le thermal fuse which is located in the resistance of the hair dryer. Do a continuity test using a multimeter. If there is no continuity, then you will need to replace it with a similar fuse.
- Le engine. Take the voltage at its terminals using an alternating current voltmeter position multimeter. If the voltage is correct, it works normally. Otherwise, it is probably defective and it will have to be replaced with an identical one.
- La electronic card. Measure the input and output voltage using an alternating current voltmeter position multimeter. If the voltages are the same, the board is working. If the output voltage is zero, lower, or not the same, the board is probably faulty. It will therefore be necessary to change it with a new identical one.
