Dyson DC07 motor overheats

Hi, it's Jack at Dyson.

It's normal for a vacuum cleaner's exhaust air and casing to become warm in use, due to the heat created by the motor when it's running. Dyson vacuums are equipped with a thermal cutout device, and this will shut the vacuum down if it starts to overheat.

It's worth checking your machine for blockages, and giving the pre-filter a wash - we recommend doing this at least once every 3-6 months as shown in the video attached. Use cold water without detergent, and allow at least 12 hours for both parts of the filter to dry completely before replacing them.

As long as your DC07 is picking up as normal and isn't making an unusual noise or smell in use, there shouldn't be an issue. But if you're concerned, you're welcome to reach out to our experts for further advice. You can reach us by calling 0800 298 0298 (UK), 1-866-693-9766 (US), 1-877-397-6622 (CA) or 1800 239 766 (AU).

A DC-7 has a Panasonic motor which is the best part of it. I have never seen one of those fail within the life expectancy. You do have to consider that a Dyson was never designed to last more than 5 years. The newer Dysons are only designed to last 2 years. If the motor runs for 15 minutes and overheats, my first guess would be a faulty heat sensor on the motor. If it ran only 30 seconds or so, probably a bad motor.

This can happen , normally if the filters are kept clean and replaced now and again the motor should last quite a few years if it does overheat then it has a thermal cut off that resets after it cools down ,,Hope this is of some help

The "hidden" filter at the base of the unit is the HEPA filter, there is another filter on the side of the vacuum that you can remove and wash with water. Make sure that is washed out. If it's too dirty it will restrict air flow and the motor will overheat.

This is a sure sign of a blockage. The motor cuts out because it gets too hot and will start again when it has cooled. Follow the instructions in your user manual for clearing blockages (you can download a copy from the Dyson website if necessary). Make sure the washable filter is clean too (and completely dry before you use it).

The motors have a "trip" to protect them, and you if a serious problem caused a fire, which can be tripped if the filters are blocked and causing the motor to overheat.
The filter at the top of the cyclone (the bit on top of the dust container) should be cleaned regularly (more often than Dyson suggest), and under the dust container you may not have noticed there is another filter - called the post motor filter. This isn't mentioned in the user book but does get clogged after a few years of use. It can be removed and can be replaced - eBay has companies that can help.
If all filters are clean and okay, it is probably the early stages of complete motor failure. If you're good at DIY, the site www.dysonmedic.com has some good info on how to change a motor. Again, eBay will help find a motor.
If you dont fancy having a go, either ring Dyson or a local vacuum repair company.

Have you tried calling Dyson? I had a problem with my Animal, and their tech department talked me though the fix. Worth trying them first.

cut out switch on the motor needs replacing this overheats and cuts of the motor when the motor cools down it will start again you have to keep both filters and cyclone clean and free of dust or after replacement the same will happen again

This is from the Dyson web page:
Get expert help Thermal cut out Most Dyson vacuums have a built in safety system that stops the machine if it begins to overheat. This usually happens because the filter needs washing or your machine is blocked. If your machine turns off on its own, unplug it and leave it for at least an hour to cool down. Remember to check the filter and look for blockages before re-starting.
Any non- domestic use may adversely affect the filter performance such as vacuuming up plaster dust.


Sounds like your vacuum is overheating. Check the above.
