E09 Hoover VHD9163ZD-80 Washing Machine?

Hi, I have a Hoover VHD9163ZD-80, its has a new motor, mainboard, console and pump fitted during the last call out 9 months ago. Basically changed most of the major parts. Now the protection cover has expired and its showing E09 and wont spin the drum. It will drain, but other cycles simply stop within a minute as it cant spin at the beginning. Could a snapped belt do this? The belt did seem more squeaky after the refit. It showed the error mid cycle after a day of back to back washes. I didnt see it stop, just noticed after some time, but it did spin up and start that cycle initially. Any idea what it could be? Thanks a lot for your help.
