tricity aw1100w washer – no spin

Hope someone here can help on this , we have a Tricity bendix 1100w washer which doesn’t want to go into spin mode, on prog 5 (long spin) it just clock and jumps to off position and on prog 10 (short spin) it does a couple or spin at low speed approx 5 seconds on higher spin then switches off. Wash programmes seem to work ok – we ‘ve checked the motor brushes and tacho ,checked and replaced motor plug connections, checked drain filter and drain pump . Does anyone have any suggestions of which way to go next.
