A problem we have started noticing with the Dyson DC25 is no power coming out of the machine to the cleanerhead.
The DC25 is notorious for cleanerhead problems; you will find other articles on Dyson Medic about it. But this is one we are seeing more and more of, so I thought it worth documenting.
This is one to check before you buy a new cleanerhead, a PCB or a cleanerhead brushroll motor.
When you suspect that the cleanerhead has gone faulty, always remove it and check that power is getting to the two terminals that feed the cleanerhead. Sometimes, people replace the cleanerhead – assuming it is faulty – and to their dismay, find the new one doesn’t work either.
There are three components that you need to look at on the circuit if you find there is no power to the cleanerhead.
One is the switch by the main power switch – test that.
One is the micro switch, and one is the loom from the micro switch. Look at the photograph below.
While the micro switch does sometimes go faulty, the fault is more often than not that one of both of the wires (the red and white ones above) have broken up.
In the photograph, they are clearly broken. It isn’t always obvious though, as sometimes they break up in the sheathing making a visual diagnosis difficult.
Give them a wiggle and a pull, as they usually break in the same place. If they are broken internally, it wont take much persuasion to make them come apart like the photo.
Easy fix you probably think……….
We used to fix them with a bit of solder and a heat shrink. Not only is that very fiddly to do in the confined space you have, but we found them coming back again a few months later with the same fault.
The problem is that those wires flex when in use, so any repair is likely to be stiffer and it simply causes them to flex at a different point and break again faster.
The easy answer is a new loom section.
This part is available on its own.
This is how it comes.
We find now that this is the only long term fix for this problem, and any repair is just a temporary bodge.
So, where to get one from?
