DC39 mystery fault
« on: July 04, 2021, 09:01:53 am »
Hi guys,

I have a Dyson DC39 Animal vacuum cleaner with an animal turbine head fitted.

The vacuum cleaner has good suction with the other heads I use and also when no attachments are fitted, but the animal head has started misbehaving.

When the head is attached the roller spins and is quite happy to spin on tiles of wooden floor, but when I move onto a low pile carpet the head will not rotate and hardly picks anything up.

I've taken the head apart and cleaned each end of the roller and removed all dirt and fluff.I also unscrewed the recess screw and cleaned behind the rubber disc which sits at the one end of the roller.I really thought that may be the problem, but there was hardly and debris behind it and to my disappointment this made no difference.

Any ideas would be very gratefully received.

Thank you

if you have stripped as you have said it sounds like you need a new head

Thank you for your reply.

I can see nothing wrong with the head.

Why would the turbine turn on hard floor but not on very thin carpet?

Because the vacuum driven turbine inside it breaks and turns on the shaft when put under pressure.

Hi MVacs

Thank you for your reply.I understand what you are saying but do not know how to check this.

Please can you send me a link of how to check the turbine?

I took out the 4 screws to release the head, pulled out the part that spins and removed the little recessed screw to check for debris as per a very useful youtube video.

I am just a female with a T10 torx screw driver and no one to help me here, so more detail would be great.

Thank you very much.

It will be that. They're known for it.

But here's a topic that should help.

Thank you for your reply.

I have just spoken with a friend who had the same issue and one of the belts had come adrift.
I can't afford to buy a new head, not even a replica, as out of work and no benefits so I'll hunt down a circuit diagram and try to find out how to strip down to view the turbine and repair it.

Thank you for your reply.

Someone came around with a new head and it did exactly the same thing, so it is not the head, at all.

When I can I will pass the machiine over to a dyson tech to check out
