Hi I wonder if anyone can help, I changed the brushes on our washer the other day and it now works again however, it now produces an intermittent noise. It is not the drum as it can happen when the drum is still but it is like a ball bearing is inside the washer. I think it is coming from the motor as I say it happens when the drum is idle but the motor is spinning and it is not constant it can appear and disappear could I have displaced something in fitting the brushes? I am sure I put them in the right way round but the noise is definitely a worry.
