Machine runs for about 5 to 10 minutes then shuts down as motor TOC operates. Outer casings get hot. I assumed it was a motor fault so fitted a new motor but the problem is still there. I have hoovered the filters but not washed them. Any thoughts?
Re: Dyson DC07 Overheating
It’ll probably be blocked in the cyclone part which doesn’t come apart, we’ve had lots of these and a replacement is the only solution.
You should notice a loss of suction as well with this though.
If you have the Connections DVD, in Mediator it’s position 18 (lots of colour options).

Re: Dyson DC07 Overheating
Sometimes it’s possible to clean the old assy out with a very powerful jetwasher. It just depends how blocked up the old assy is. Strip it down as far as you can, and give in a good blasting.
Re: Dyson DC07 Overheating
I took off the top bit and poked a rod down each of the cones but could not feel any fluff in there. There is good suction at the air passage hole with the cyclone assembly removed. With it on, if you use the crevice tool (always sounds like some kind of mountaineering gear) there seems to be no suction initially but it builds up after a few seconds if you block off the nozzle. It looks like the centre section of the cyclone assembly is held with 3 screws but is also glued. As the cyclone assembly is almost as expensive as the motor I want to be sure that is the problem before I order one.

I guess the only 100{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d} way is to swap it for a known good one, but as DC07’s are quite new 🙁
I’m 90{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d} sure it will solve it though

Re: Dyson DC07 Overheating
It is glued.
The only other blockage problem I get with them are coins stuck half way down the handle, (swine to remove) but just take off the handle and eliminate that.
There’s really nothing else to block up on the vac.
Re: Dyson DC07 Overheating
I’ve repaired quite a few. You could try running it without the filters and see if it still cuts out, if it does I would certainly say the cyclone needs replacing.
MervRe: Dyson DC07 Overheating
Thanks gents, I renewed the cyclone assembly and it has done the trick. In fact, I think when I tested it some of the muck was drawn up from between the floorboards and through the carpet :tup: I sawed up the old one to see where the blockage was. All I could find was little balls of fluff blocking the black jets that are fitted in the centre section, one for each cone. The next time I get a job like this I will blast it with the airline, using an inverted funnel pushed onto the rubber airline hose. If I hold the funnel against the bottom hole in the cyclone it should get the full pressure to blast out the fluff.
Re: Dyson DC07 Overheating
Had another one of these with the same fault and managed to clear the blockage. No joy with the airline but I lifted the lid bit of the cyclone, illuminated it with a halogen inspection lamp, poked an old bicycle spoke down each cone and fished out lumps of fluff from the jets. You also have to turn the cyclone upside down and give it a good slapping to shift the fluff to the top ends of the cones. 8)
