Blomberg 1501AAA. Please help solve the problem, the washing is building up and the wifes nagging. The washing machine stopped in cycle so took the back off, drum would not revolve, looked at the motor, brushes worn, replaced brushes, reassemble. Washes OK but trips ELCB (not MCB) when it finishes rinse. Drum rotates OK on wash but does not move on spin. Machine about four tears old.
