Hi, found you on Google - where else?
I have a SEBO X4 which, after being used for years, recently and without warning, appears to have burnt its motor out. I bought a replacement motor from you which I fitted yesterday.
Now I have a problem!!
Although the motor is spinning freely and it appears to work as long as there is no load on it, as soon as is it used on even a hard floor, so there is only a light load, there is a distinct burning smell as if the brushes are arcing badly. Using it briefly on a carpet makes it a lot worse.
I'm concerned that the burnt out motor was the symptom of another problem and unless that is sorted before we use the SEBO, this motor will burn out too.
There doesn't appear to be mechanical issues so this has become a real puzzle!
Does anybody have any ideas?
