My Miele S5261 Is Making A Popping Sound And A Bad Smell - How Do I Fix It? 

Yes fully agree but they are shouting out they are on a way to become "green". Lol

A new motor is $200.00 plus shipping...

@@1953childstar exactly. A New v. cleaner in the Netherlands cost aprox €230,-. So in my view these big brands do everything to prevent a repair. They make spares extremely costly. Or you need special tooling or its impossible to get manuals.

​@@petervegt6971 yeah cause we always have to consume. spend more money and pollute the environment. it's consumerist society after all. worst are mobile phones ofc.

Because it's a variable speed motor.

morhywaden My Miele vac cleaner [ 'Electronic S311i] has just packed up... the motor / vac unit is giving out after more than fifteen years good service and some serious abuse.... the new one that, the complete vacuum cleaner!!!!!!! i'm looking at is only 155 Euros....here in Ireland..... happy days....so maybe time to just buy a new vac as they come with a two year guarantee... ..this new one may out last me... www.soundstore.ie/Product/miele-seaco-c1-powerline-cylinder-vacuum-cleaner/7192/2213.3.0

yes but how do you know if this popping noise and burnt smell is the brushes??

Hi there, unfortunately on this and most recent Miele vacuums there is no way to replace the motor brushes on the motor. The newer Miele machines have whats called sealed motors and you replace the motor as a complete piece.

VacuumSpot Thank you for your care and response , I noticed that too and as you said I had to replace the motor , but I see it is not economic

VacuumSpot do you know when the miele s7 was introduced?

there is a way to do it

Easy to change brushes. They are not sealed

This is only a demonstration machine to show the process of replacing the motor

Carbon brushes on motors don't last forever. Eventually, they will wear out causing the machine to make that popping noise followed by that strong acrid burning smell.

@@jayambermsp8000 Why not replace the brushes then? A new motor, I was quoted 84GBP, brushes for other vacs are like 6GBP. Mine makes no popping noise but does smell of hot brushes/rotor after the bag failed when I used it with my cross saw on wood. I cleaned the motor, it looks like new. Field coils look fine, commutator looks ok, copper picks on it look a little dark but nothing i've not seen on other motors. I will check the brushes and see if i can get OEM, perhaps the radius in them is to large spanning to many coils. I never checked in detail when I had the motor out as I thought it was the dust build up inside. I did look a little at them through holes with torch and without pulling them they looked fine

I think its probably water

Mines doing the same. Brushes were gone just about. 2mm left. Got new ones. Still pops. Bad windings?

@@bl0wfish Commutator is shot...

Nice. Mine ended up being bad also haha
