How to Replace the Brush Bar Motor on a Dyson DC24:
Maybe you have read our other article: Dyson DC24 Brush Bar Motor which describes what to check if your brush bar (brush roll) on your Dyson DC24 isn’t turning? To recap, before we suspect the worst, look to the front of the machine on the cleaner brush head. On the left side is a small button. This is a “reset” button. Power the machine on and off whilst pressing it a few times. Do the same with the small brush switch next to the main power switch.
Remember that the brush should only turn when the machine is reclined. It will not spin when the machine is standing upright. The brush bar motors are prone to failure. This is a design fault in our opinion.
There are two electrical components in the cleaner head that can go wrong. The brushbar motor and the printed circuit board (the PCB). Experience has taught us that although the PCB’s in the DC24 do burn out occasionally, 99.9% of the time the brush bar motor is to blame.
To be sure, you can strip the head unit down, remove the motor, observe the alternate DC voltage it takes, and bench test it. So now you need to know how to strip it down. Start by removing the cleaner head which is done by removing the c-shaped clip as shown here:
You actually do it from the front, using the little cut out, but I am doing it from the back here to better show you the clip in question. When you have removed the clip, the head unit comes off like so:
Look on the underside, there is a rubber strip. Pull it out and put it to one side (as there are screws underneath it). Your next job is to undo the nine screws with a T10 torx screwdriver. Here are their locations:
Having done that, release the end cap. I use a two pence coin………
Having removed the end cap, you can now take out the brush roll:
Now you can split the unit like so:
Now you need to unclip the circuit board. There is a little clip that releases it as shown:
This allows you to split the unit a little further:
Now you can unplug the motor from the circuit board. There is now one screw holding the motor in place. It is a T8 torx screw as indicated by the arrow in the picture below:
Having undone that, the motor comes out. Replacing your motor is simply a reverse sequence of what you have just done.
If you want a quick video recap of all that, you can watch the video below by clicking on the “play” triangle:
