Hi, Got a burning smell from it so investigated. The belt is well worn and has been rubbing and one of the bearings in the Brush Bar was seized so I presumed that's the cause. However, the post motor filter and casing is full of black and has the same burning smell.
Not sure if that's just normal carbon dust from the brushes and it smells from the burning belt or the motor is on it's way out.
It's about 15 years old and the motor doesn't sound sick but do you think it's on it's way out? Don't want to put new filters in for it to ruin them when it dies shortly After.
I would open it and check but the clips are knackered and it's been riveted shut. Don't want to drill the rivets out before I've got a replacement housing incase it won't go back together.
