ive got an elec schematic @ home for this machine, and ill check but I dont think that you should be getting 240 on the neutral side of the solenoid. Can you trace the neutral wire and see if its been disconnected somewhere (with the power off and machine unplugged of course). Also look for any loose solder joints or bits of broken track on the PCB. I had to solder in a jumper wire on my old one to make the pump work due to faulty track that was stopping the pump from running.
I hope you have enough skills to be safely playing with water and electricity!
Good luck! :)
