We noticed this noise that was getting louder during spinning, it sounded electrical (reminded me of the humming you hear with electric cars which uses small wire brushes to get power from the track); tonight the fault from the machine got the the circuit breaker to go off, now no turning at all or spinning, machine fills/empties fine, there is some resistance when I turn the drum so I assume the belt is fine... from looking at eSpares videos it looks like this could be Carbon brushes? I hope I dont need to change the whole motor though? Just checking before ordering. I ordered parts before from the website and always satisfied, but this is my first question ... thanks in advance
