Hi. I have a Bosch WFL 2260 washing machine. I have replacing the brushes and it did two washes without any problem but now refuses to turn most of the time. If I leave it for a couple of days then switch it on again then it will turn for a few seconds but then stop turning. The timer clicks and it finishes the wash cycle, but the drum does not turn. I think I have installed the brushes correctly since if I put them in the other way round then I can see it does not make proper contact with the motor armature. Please help. Many Thanks in advance.
