Could be diverter valve but as a fuse has blown it could be the PCB. Will need to be tested following the manufacturer's fault finding process.

Gotta love a Chinese Worcester knock off . Could be the diverter valve/motor. Fuse could be the pump, electronics et al.

See this OP's other posts, it seems he has been doing lots of faffing about with the systems electrics, which might explain the blown fuse. He also seems to be opening up a room sealed boiler. I wonder if he is gas qualified?
