bosch wft 2800

went to this machine the other day not spinning..checked motor and sure enough one of the cbs had worn down..its the motor that needs a full end frame so i ordered one fitted it expecting nice simple job…now the machine when on spin rotates a couple of times then just goes dead..light showing spin still on..if put onto wash does the same…fills..rotates couple of times..one direction only..then stops..if supply is switched off it does the same again… door remains locked,,customer says was ok before..now im thinkin prog or module faulty???..heater ok n no blockages pressure chamber..any ideas please??
