Washing machine drum wont turn, machine will fill up and empty.removed back of machine the motor is not running. I removed and checked brushes they were fine. If you put a neon screwdriver on the brush terminal with the machine in spill cycle the screwdtiver lights on both brushes showing ther is no neutral. Is it a case that the one wire has gone open circuit and getting its live through the motor? Do you think it could be a circuit board fault? Thanks in advance for your help.
