Hello, my name is***** be patient whilst awaiting any responses as I'm not constantly available.

George-Allsorts :

How long has the fault been there and have you had any cut in power supply to the boiler prior to the fault appearing

George-Allsorts :

F73 is indicative of the water pressure sensor being defective or a short or fault in the wiring to it. It is not a do it yourself job.. You are well advised to call a Vaillant engineer in.. You can call Vaillant Ltd on #0845-602-2922
