Question about Dirt Devil Reaction Twin Cyclone Upright Vacuum

2 Answers

Vacuum shuts down after a short time and needs to cool off before being restarted.

It shuts down like it's overheating, but it's less than 60 days old and the canister is emptied often. I saw in the user guide that it could be the thermal detector, but there is no diagram of where this is or how to fix it. I lost the paperwork for it so they won't do a return or repair.

    unsure if this is the same problem or not with mine . Im sure that it is, and I am not the original owner of this vacuum so I don't have any of the paperwork to figure out how to troubleshoot these issues. I need to find the repair manual and or the replacement filters for this vacuum.

    I have cleaned the roller and cleaned the filter really well that didn't help, even bought a brand new filter. Didn't matter, Im going to try to replace the belt, and see if that makes a difference but it seems every time we use it the time between we turn it on and it overheats is getting shorter and shorter I was really happy with this vacuum for the first few months now its a nightmare!!! I've had a kenmore, a hoover, now a dirt devil, they are all so expensive I can't keep replacing them and I don't know what brand to even trust.

Could be the protector, it usually is located by the motor. But I am sure that this has a 1 year warranty on it, so if it is less then that, take it in for warranty service. But it also could be that you have a clogged filter, hose is clogged, or the dirt inlet by the brush roll is clogged. A clog will cause the motor to overheat and shut down until it is cleared.

Was cleaning the floor and I shut it off to empty the canister and it wont restart

Not knowing your model of vacuum I'm guessing it could be your cord or switch is bad. If the vacuum overheated it should come on after it cools down but that is a good sign it's time to change the filters

My Dyson V6 is 3 days old. It worked great Day 1 & 2. Now it seems like the motor "surges" on and off and on and off so I can't use it properly. The canister was barely full but emptied it anyway.

Hi Christy, it's Jack at Dyson.

If your Dyson V6 cordless vacuum is pulsing on and off, this will be due to something preventing airflow from passing through the machine. Once you've checked the floor tool and wand for any blockages, the next thing to check is the bin inlet, as well as the bin inlet flap. It's possible some debris could be jamming the inlet flap shut. I've made you a quick video to help you with some further troubleshooting, and I'm confident this will get your V6 up and running again.

Vacuum runs for 5 minutes ,then shuts down. Will restart after 15 minutes, then does same thing.

sounds like a built in feature. It is overheating, bad wire or circuit possible

Why does the power shut off on a dirt devil vision vacuum?

It is probably the thermal sensor which shuts the vacuum off it gets hot. It will come back on when it cools down. Replace all the filters as they are probably. Restricting the airflow

My vacuum was making a funny noise and had a bad smell

Hi John, it's Jack at Dyson.

Most Dyson vacuums include a thermal cutout which shuts the machine down for protection if it starts to overhead. You should find it will run again after it's cooled down for around 2 hours.

This is likely to have been caused by a blockage, or because the filter is overdue for a wash. To prevent this from happening again, please follow the steps shown in our Support guide:

In normal use, the filter needs to be washed 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 sections of the filter to dry completely before replacing it.

If you'd like some further help from our experts after you've given both of these steps a try, please call the Dyson customer Helpline on 0800 298 0298 (UK), or 01-475-7109 (IE).

If it shuts off after being used for a whirl and won't come back on for a while it is probably overheating. The heat sensor shuts the machine off and won't let it turn back on until it cools down. If this is the issue it could be the filters are clogged and not allowing enough airflow to keep the motor cool. Most bag less vacuum filters should be replaced frequently even if they are cleaned regularly.

Dc05 cuts out

Hi George,

I'm sorry to hear you're having difficulty with your DC05. If the machine is shutting off in use, it may be overheating due to a blockage - the filter may also need a wash. You should find it will run again after it's had time to cool down, but to prevent this from reoccurring, please follow the steps shown in our online Support guide:

This should resolve this issue, but if you'd like any further assistance or advice, please call our Helpline on 0800 298 0298. Calls are free from UK landlines, and we're available from 7am until 10pm, 7 days a week.
