Truma Combi Boiler Fault No.45 SSLSLLSL
My gas bottle ran out while the heating was on and we didn't have electric hook up. We changed the bottle but the red fault light behind the control knob comes on. Gas is getting through from the new bottle because the cooker, fridge & bbq point all work. When we got home the boiler works fine on electric but not gas. I've done some research and have established that I have a Flashing Error Code No.45. I,ve checked the 12v 10amp fuse and the 230v 10amp fuse and both are oaky. I've also pressed the over heat reset switch although it didn't appear tripped. I think it is a fault with one of the PCB,s as when on hook up and set to gas the electric heating works, not the gas. Unplug the hook-up and the gas fault occurs. Any one got any ideas as to what the fault might be please as I am snookered and daren't go away without the heating working properly until summer. Thanks
