Hi , on a spin at the end of wash the washing machine sounded louder than usual and gave off a slight smell of burning. Upon investigation it appears 1 of the carbon brushes has melted slightly the plastic surround. The brush has plenty of life left in it (length) so unsure why it has generated so much heat and melted some of the housing. I have checked the part of the motor it connects to and no obvious issues / reasons why it should have happened? Is it worth replacing the brushes or will the same happen again?
please note the unit is only about 1 year old but had stood unused for around 8 month then this occurred on the 2nd cycle following the gap in use . Your help is much appreciated.
