Hello all
So here’s my dilemma
When CH is on and I run HW both pins are lifted
When CH is off (but in CH & HW mode) and I run HW both pins lift, I get HW then when I switch tap off but before boiler shuts down as normal I get the 60 light flashing the rear pin then drops and the 60 fault light extinguishes.
Any ideas?
TIA
Stu

something is telling the board that, the heating is not needed,and the pump is shutting down, it could be the timer/programmer, the heating sensor the circuit board or even the diverter itself,

yea mate, both pins need to move, for hot water but only the back for heating only  |

when in hot water and heating, the heating is not working because priority is given to the hot water,

so thats our problem then, that pin should drop as the pump shuts, you can get a kit to service the diverter, its fiddly but doable
