I have a DC41. The power head wont turn and is making a squealing noise.

Hi, have you checked to see if something is jamming it . Ok nothing there the dyson brush head has a small motor and circuit board this may have blew the board or burnt the small motor you will have to get the brush bar unit checked.

Hi there, it's Jack at Dyson.

DC41 is engineered and tested to work across a wide range of hard and carpeted floor types. The soleplate adjusts automatically for optimum performance, and the brush bar can be switched off to protected hard floors, delicate rugs or long pile carpet.

We're keen to take some additional details about your DC41 and the particular carpeting you're having difficulty with - we may have some suggestions that will help. We'll also check your particular DC41 is working as well as it should be.

When you have your DC41 easily to hand, please give the Dyson Customer Helpline a call on 0800 298 0298 (UK), 1-866-693-9766 (US), 1-877-397-6622 (CA) or 1800 239 766 (AU).

We'll look forward to speaking with you.

the bearings at the end of the roller brushes need lubricating. The belt may be too shiny to be useful now so replace it after you lube the brush

Hi there, it's Jack at Dyson.

I'm sorry to hear about the issues you're currently experiencing with your DC41 Animal, but from your description of the problem I'm confident that we can resolve this for you.

Just to make you aware, it's normal for dirt and debris not to spin within the clear bin - in fact, at the base of the bin are four 'baffles', engineered to capture the debris from the airflow and force it to settle. This isn't in itself an indication that there's a fault with the machine.

I'd like to take some further details to help get your DC41 up and running again. At your earliest convenience, please email [email protected] and our experts will be in touch. We'll look forward to hearing from you.

Ouch The video below shows how to to remove the brush head and how to clean it. I almost think that Dyson didn't ever expect this belt to break. The rest of the disassembly to get to the brush seems to be done by removing torx screws, I have not been able to find a replacement from dyson. A google search shows several sites that sell a replacement belt.

Hi Stacy, it's Jack at Dyson.

This issue you've described with your DC41 sounds unusual, as the changeover valve will divert suction to the cleaner head automatically when you recline the machine into the vacuuming position. If it's not doing this, it's possible you have a blockage somewhere in the cleaner head, internal hose or changeover valve.

To check for this, please follow the steps shown in our online Support guide: http://www.dyson.com/support/dc41/dc41-irspu/diagnosis-root-menu/performance-flo-area-check-dc41/flo-brushbarvid-dc41/redirect-to-performance-flo-base-dc41-checking-the-internal-hose/performance-flo-base-dc41-checking-the-internal-hose

If you'd like some further advice after you've given us a try, please email our experts with your details at [email protected]. Someone will be in touch to help as soon as possible

Have you checked the electricity is getting to the motor? You can replace the motor if necessary.
