Dyson DC25
« on: April 30, 2014, 03:09:54 PM »
Hi all this is my first post, thank you in advance for any tips.

I came home to my wife telling me that our Dyson had blown the electrics in the house.  The motor still works and the suction is good, so I stripped the brush bar and the motor has given up the ghost. I ordered a new head and it still doesn't work I have reset the reset switch, though it doesn't feel like a positive reset. 

Does anyone know the voltages I should have at the connection point for the new head and at the reset switch?

Thanks again Nick

If you have put a new head on and it still doesn't work, I suspect this part.

You should have normal mains voltage coming out of the cleaner to the cleanerhead. The change to DC happens inside the cleanerhead to fire the small motor.

Have a look at this topic and check those two wires.

The one by the power switch? That is a basic on/off. No trick to it.

Remove the head, get a tester, recline the machine, see if there is power coming to the two terminals. If not, try the brush switch up top once or twice. If not, check the wires linked above, if they are OK, suspect the microswitch.

Its simply a case of following the lack of juice back bit by bit from the cleanerhead. Or down from the switch; whichever you prefer.

Having ruled out the cleanerhead, in order of what we use and what we sell, the loom is next likely culprit followed by very occasionally the microswitch. The switch up top is least likely, they are a very good switch they have used for years across many models.

Thanks again for the help, I am getting 24vac at the pins and then the same at the tilt micro switch.  If I should be getting 240vac I seem to be missing 90% of the power.

I am not getting any resistance across the reset switch either, think that may be the problem.  Plus when I removed it it's really raterlly,

Just bypassed the reset switch and the brush bar is working  ;)  when the motor went it took out the PCB and the reset switch  >:(.

I can now replace the reset switch and we can use our baby again ( better than spending hundreds as my wife wanted to!!!)

The switch is the least likely, but it just goes to show it can be that.

The cleanerhead you bought is a good buy anyway. You will use the bits off the old one like the brushroll and end cap too in the future.

No hundreds of quids!  ;D
