Why won't my brush bar come on
replaced cord and brushes will not come on now
I have a Dyson DC77 animal + allergy upright vacuum. I assume the design of my vacuum is similar to the DC24. The DC77 is bigger and has added paper filters behind the "ball" wheels. I had the same problem with mine. A small lever switch inside the vacuum "ball," which controls power to the beater brush, is turned on when you move the handle from the vertical position to any other position, and turns it off when you place the handle back in the vertical position. If you remove the "ball" wheels you should be able to see the switch on one side, and the plastic assembly that turns the switch on and off when you move the vacuum handle upright vs. horizontal.
In my case, the beater brush was intermittent. Sometimes it would run and sometimes it wouldn't. Once I disassembled my vacuum far enough to access the switch, I checked the continuity of the switch as I pressed down on the switch. Though it seemed unlikely, I actually found a dead spot on my switch after it turned on, but while pushing the switch lever further down to the final "on" position - same as the vacuum handle in full horizontal position - the switch turned off and then back on again once it reached the final "on" position. I know the beater brush has stalled on a piece of yarn from the carpet, and suspect it may have burned a spot into the switch due to the power surge that occurs when an electric motor stalls out.
On the power supply board inside the "ball" that provides power to the beater brush motor, I unplugged and re-plugged the wires on the power supply board to make sure they were making contact. I ordered 2 switches (one back-up), and reassembled my vacuum until the parts arrived. What's interesting, is that I still haven't put the new switch into my vacuum. My vacuum started working OK after I reassembled it while waiting for the parts to arrive. I know my switch has a bad spot, but it's working. It's possible that the wires to the switch came loose from the motor or motor power supply, and my "playing" with the wires fixed the problem - I'm not sure, but I at least I have two new switches on hand when the beater brush finally stops turning permanently.
One final note, it looks like the lever switch is soldered or welded to the wires. I can't tell for sure, because the switch terminals/exposed wire ends are covered with heat shrink tubing. If you have to replace the switch, you may want a couple of pieces of heat shrink tubing on hand to restore your vacuum to its original condition. You may be able to buy the switch with the wires attached, but all I found was the bare switch, which I bought from PartsDirect.com
+1 for Gary's answer. I have a DC25 that had the same behavior. I overhauled the power switch mechanism more times than I care to remember without luck. After reading Gary's post, I dug into the angle release mechanism down toward the wheels. I found the switch that is triggered when the vacuum is released from vertical, cleaned the contacts with a small file, and reassembled with a little dialectic grease. On mine, the switch was in the levering mechanism, not in the ball. Everything works great now.
The answers to this question helped me and I thought a picture of the switch near the ball would help. I am pointing to the black switch with a pen in the photo. 3 screws and you can get too it. In the photo you can see the cover removed after the screws are taken out. Also mine looks slightly different as the wheels that hold it upright when stored broke so I just took them off.
You might have a bunch of hair or something tangled up in their. Look at each ends of your brush. Get some scissors and cut the problem off/out. Or maybe the belt came off PR broke.
Dyson 24 is junk , not good at all on shag carpet , beater bar is a pain now mine just stopped spinning , out with the garbage
my dyson dc24 wand is stuck and wont release out of the mecanism the red button will not release the wand
User knowledge first, I use this dyson rarely and always forget this:
I have an older Dyson and to get the brush bar going you just hold down the base (with your foot normally) and move the handle down out of the upright position. Voila, the brush spins. If you do that with this one, the bar does not spin. This one requires you to start it by depressing the red bar at the rear of the base (with your foot). I have had to relearn this at least 3 times. :)
THE JOHNSON DF651(2)LG DYSON DC24 Vacuum Cleaner BRUSH BAR MOTOR USED IN THE US MODEL OF THE DYSON DC24 ONLY LASTS ABOUT A YEAR! NO REPLACEMENT MOTOR FOR THE US MODEL IS AVAILABLE, ONLY A 220- 240 VOLT DC IS AVAILABLE IN THE UK. IT IS NOT COMPATIBLE WITH THE US MODEL DC24 AND CAN’T EVEN BE SHIPPED TO TH US. THIS IS A DEFECTIVE MOTOR AND DYSON OUGHT TO REPLACE IT FOR FREE UNDER THE LEMON LAW! (AS IF THERE WERE SUCH A LAW) THIS JOHNSON MOTOR IS JUNK AND THE ONLY WAY TO REVIVE A DC24 WHERE THE BRUSH BAR DOESN’T TURN IS TO PURCHASE A NEW DC24 CLEANER HEAD ASSEMBLY!
My brush stopped working on my DC77 tried all the tricks and nothing worked. Let it set overnight and the next day it works again. I guess it was just tired
My brush on my vacuum dont go
I've checked the switch on the bottom near the ball, checked the belt etc.
I am getting no voltage at the end T brush car connection, no voltage at the motor?
Brush car switch near on off switch is working ok?
Cant work out where the vault is now? Do they have a main control board before I start searching for a broken wire
yes please id be thrilled to put it to use. thanks.
I know this is an old thread but I found it when I had the same thing happen on my Dyson Multi Floor 2. Brush bar would come on and off intermittently. My solution ended up being a little differant so I wantes to share in case anyone else came across it. When you remove the brush head, there is a grey clip and the whole thing slides off. Part of that is a plug assembly on top. On my machine the female side of the plug that stays with the main machine, the contacts inside had come loose in their holder. There is a clip of sorts that holds them in and it had come unlatched. All I had to do was remove one screw on either side of the plug to slide the cover back and gain access, pull the plug out a bit, push back in and turn the contacts so they were fully seated and rotated so the clip's ears held them forward, press the clip back down with a pair of pliers and reassemble. My wife tested it out and it seems to be working perfect now. Wish I had tried it before spending $300 on a new Shark Cordless, ???
