Any idea what is wrong with my boiler ? The CH only works if HW is on too. Once the HW is off the display then shows FL. I thought it might be a fault with the 3 port valve, but I can't find one, there appears to be two 2 port valves instead (?). Help appreciated.

Thats more than one fault.
LF is a boiler fault and the heating fault will likely be the valve.
Youll need a gas safe reg engineer for the boiler fault so ask him to look at the other fault whilst hes there.
