The washing machine was working fine until half way through the wash at which point it just stopped and all the lights went off. I tinkered about around the motor; taking off plugs and re-fitting them etc. I also tightened up the wires to the brushes and when I put the machine back together it worked and finished the load. I then filled the machine up again to do a second load but it was completely dead. Is this the motor or is there something else that could be wrong. G
