Motor Short on Hotpoint WT960P?

5 year old Hotpoint Ultima WT960P washing machine. Problem started with an F-01 (short circuit motor triac) fault code on the display. I replaced the motor control board PCB at £65 - but it then became apparent that there was continued flashover on the motor. I replaced the motor itself (thinking short in windings), but the motor flashover continued, and now appears to have blown the fuse. Where/what is wrong with this machine. ? What/where should I try next ? Is it possible to obtain a wiring diagram to check where the electrical fault lies ? Any help that could be given greatly appreciated. I am at my wits end !!!
