I've heard of the loom breaking up, there have been many threads here on the subject, but, last week my first one came in! Dead brushroll housing. I look at the loom first now as it's the easiest thing to start with, and sure enough, the white wire was snapped.
For a quick diagnosis, with the PLUG OUT OF THE WALL I stripped each end of the wire, twisted it together, wrapped it in electrical tape and voila, one perfectly working brushroll. I suggest you try this is you are competent enough, as it could save you money chasing faults around. The PCB and/or Motor could have gone pop as well, you never know!
Diagnosed, I need a new yolk loom.
So, INGREDIENTS:
1 Yolk Wiring Loom - Only available here! -
DC25 Yoke Loom Assembly1x T-15 Torx driver available here:
T15 Torx ScrewdriverMETHOD:
Remove the cyclone and brushroll housing (can remove the wand and hose if it helps you!)
Tilt the machine so this cover looks at you (and questions your pint)
Remove the three screws
You will see my repair to the bottom white wire
Remove the white and red bottom wires (of the yolk loom) from the housing.
To aid getting the red wire out of the brushroll switch, the switch housing simply pulls away from the chassis. You want to remove the right hand side wire (as you look at it) and feed the cable and connector out of the hole at the bottom
Job done, remove the silver screw
Over to the other side now. Remove the side hose by levering it off the housing either end (if yours is split as they sometiems do, you need this -
Dyson DC25 Duct Hose)
once off, remove the screw beneath
and remove the cap that holds the ball on square
Next, pull the chassis outwards, and the ball will wriggle out of the wiring side. On the other side, pull the chassis out enough to enable the ball axle to clear the housing and swing outwards slightly
You now need to unplug some wires
The top wire is Black to White. With a small flatblade, lever the spade terminals out of the housing from the top or bottom edge. To seperate, push the locking tab of the connectors in from the back with your screwdriver, adn they will seperate with ease
Do the same with the bottom wire, which is White to White/Blue
Once the wires are unplugged, the ball should drop away from the white ring
Pull the yolk off the ball
This is the back of the loom housing that we are replacing. Remove the three screws
Pull up from the screw location area, then pull the end of the loom housing out of the yolk and voila
Take your new part from Mvacs
Feed the wires through the hole, then push the end of the loom housing in. The screws end should then fit into place
Refit the three screws. Then, fit the yolk back onto the ball. I find putting the axle end in first, then sliding the yolk over the other edge the easiest. There is a bit of give in the yolk ends to help with this
Then, refit the ball to the machine:
Fit the duct hose side first, so the ball axle and yolk housing locate in that side first
Bring the other side of the ball close to the housing
Fit the white cable ring into the ball housing
Re-fit the two cables, and ensure the conenctors are locked back ionto place, and the cables channeled away. Check the wires have not pulled out of the chassis further up, if they have, tuck those back in too.
Push the ball hosuing back under the chassis so the 3 locating nubs of the motor hosuign seal locate in the holes of the chassis.
Fit the silver screw
Check all the cables again!
Refit the locating plug and screw on the other side
refit the bellows
Refit the cyclone, brushroll and anything else you took off and test!
Job done, put it into vacuum corner for collection!
