Hi All,
I'm new here (hello) and I'm hoping someone can help me diagnose the problem I have with my Sebo BS36 Comfort.
When running the vacuum motor I get a burning smell along with a dodgy noise (the burning smell set the fire alarm off!) Ive stripped the vacuum motor out and I think it looks fine, however there was a lot of carbon soot in the housing and over the motor etc.
I'm not sure what I need to get my SEBO back up and running??
Any help would be very much appreciated.
Many thanks,
Keir

What you have described are the classic symptoms of a burnt out motor: check the carbon brushes, the odds are they down to the metal.

Hi buddy,
Many thanks for getting back to me. It looks like there is still a little life left in the brushes see photo?

Bench test the motor while you have it out.

Commutator looks a little burnt out... They do go black, but normally that deep of colour they are burnt.

You can clean commutator with a fibreglass pen and replace brushes with good quality ones.
I have saved a few using the above method but generally once the commutator has started to get really hot it's life and reliability is reduced i found.
Easy answer is to replace the motor for a hassle free future. Nothing worse than spending a couple of hours working on a machine reconning the motor and it fails a couple of months later down the line, especially if it's a paying customer.
I haven't done a massive amount of work on this model, but if it has an exhaust filter - is that ok ?

I'd agree with the above. With most Dyson motors of the DC04/07/14 era, it's generally not worth it. With Sebo motor prices though, it's worth a try with just new brushes.
