I just managed to fix mine, I found it was several componants on the control board that had gone "bang", basically no one ever lubricates the belts as they should, (every three months) the board componants get to a point were the strain is just too much and go pop, depending on which componant goes depends on the repair cost etc, some bits cost a few pence others upto 15 pounds. Mine runs fine again now following the err1 code showing, and yes I have lubricated the belt since repair !
