Auto sleeper Stanton Truma Fault

Hi folks need some advice on a technical question on our Truma Boiler.
On our last trip it came up with the fault W 45 H = no 230v supply to the unit. It wouldn't heat the water on electric when on ehu but worked on gas. I have reset the switch in case it had overheated and took out the boiler and changed the 230v 10a fuse (the old fuse had continuity so was probably ok anyway).
This involved taking half the wardrobe to bits disconnecting gas and water etc and hasn't resolved the problem. More confusing is the heating side of the boiler will work on electric but the water heating side doesn't has anyone else had this problem and if so how did you get it resolved.
Many thanks in advance for your assistance.
Best regards Mary and Alan
