How do I get to the impeller on my Hoover steam vac dual v to get to the rotating brushes to fix their rotating

First, there is no impeller that turns the brush. It is controlled by a turbine assembly. There is the brush with the middle stem (know as the brush block) and the turbine turns the brushes.
Turbines cost $39.00
Brush Block Assembly cost $34.00

Can't activate front brush

Hi Sandy, it's Jack at Dyson.

DC25 has a belt engineered to last the lifetime of the machine. It's protected by a sensor which shuts off the brush bar if something jams it. If your brush bar won't rotate it's likely it just need to be reset. Please follow the steps shown in the video I've attached.

Tip: Once you've checked the cleaner head for obstructions and removed any threads or hair from the brush bar, recline the machine into the vacuuming position. Turn it on with the red on/off switch, then press the silver brush control switch twice.

Please note: The brush bar will never rotate when the machine's standing upright, so make sure you recline it down into the normal vacuuming position before testing it.

I'm confident this will resolve the issue, but if you would like further advice after you've tried this, please get in touch with us directly. You can reach our genuine Dyson experts by calling 0800 298 0298 (UK), 1-866-693-9766 (US), or 1-877-397-6622 (CA).

The brushes do not disengage when in upright position

Set the brush control, as needed. The brush control turns the brushbar on the underside of the vacuum on and off. The button is located beside the power button, on the top-front of the vacuum cleaner. Turn on the brush control for cleaning carpet. Turn off the brush control for bare floors or delicatelb_icon1.png rugs..

Brush wont turn belt not broken no sure how to get to shaft to see if it is turning

Hi there,

Sorry to hear you're having difficulties with your DC07. If the brushbar in your cleaner doesn't seem to be rotating, please check you have the brush control set to 'Carpets', as it won't rotate when set to 'Hard floors', or if the cleaner is standing in the upright position.

If the brush control is set correctly and the brushbar still won't turn, it's probably best if you get in touch with us directly. One of our experts will be happy to run through some troubleshooting over the phone with you, and recommend the best course of action. You can call us free on 08002980298 (UK), or 1866MYDYSON (US).

Kind regards,

The brushes won't spin. I put new brushes on and it still doesn't spin.

Usually when the brushes won't turn it is due to a bad turbine. Insert a screwdriver into the square hole that the pin on the brush fits into, and see if it turns. If it is seized up, the turbine assembly will need to be replaced.

Dyson DC 14 Animal - The carpet brush does not turn. I cleaned thoroughly per the instructions but the brush does not turn. I tried moving the carpet/bare floors switch with the same results - carpet...

The brush will only spin when the machine is reclined. Not when the machine is stood upright.
If the brush doesn't turn when the machine is reclined, and the brush control set to "auto", you have a brush bar and/or belt problem.

Brush bar is not turning when I turn on my dison vacum

Hi There,

The Dyson DC15 All floors is actually a 2 motor upright, meaning the suction motor is separate from the motor that rotates the brushes. The first thing you should check is the reset switch on the brushes. Behind the brushes there is a little red pole, push this down to reset the brushes, and see if this fixes the problem.

If not, then you may have a bad on/off switch for the roller brushes. Try pushing the switch next to the main on/off switch that controls the brushes up and down, up and down, can you hear the brushes attempt to come on at all? If you could hear them come on even somewhat, this means that your brush on/off switch is bad and needs to be replaced.

If nothing happens when you push this switch, it still may be bad and not getting any power at all to it.

Does the machine make any sound at all when you try to turn the brush switch on and off?

Please try pushing the reset switch, then testing the on/off switch first. If neither one of these solutions works, please just use the comment field on the repair and let me know, and I can then walk you through some more advanced diagnosing of your machine.

Check two things with this model: if the top slider button has been activated it will turn the brush roll on. If not then you'll have to remove the sole plate and check the sides of the beater bar - sometimes this will get jammed and refuse to turn because clogging of dust or tangled hair/carpet thread takes up the thread wheels at the sides. Sadly this model has a permanent toothed drive belt that can't really be replaced by the owner. However check the slider control on the top of the main body / handle first before doing anything - as you know it has a two option slider - switching on without the brush roll function and switching on with the brush roll activated.
