Hi if you can find a small 15mm pipe coming in to the boiler follow it and there should be the start of the filling loop.
yes please do
ok on picture ending 415 a the back behind and above the flue looks like your flexi hose
its obscured slightly by the roll of copper with the green sleeve
yes around 1 bar or 1.1
But you say there is no lock out light on the burner?
Ok so you have 1 bar or over water pressure. you are calling for heat or hot water You left the valve that you tried earlier in the same place you found it and you definitely have no Red lock out light on the burner.
Then this sounds like the diverter valve is failing when you turn the heating on and turn the dial for hot water to off can you hear the diverter motor running
Nope its picture 405 plastic box with writing on it
Yes I didnt want to insult.
on top there is a slide just try moving that across when you have heating and hot water switched on
ok so its not seized. Well im sorry but I dont think there is a lot you can do without testing for power through the motorised valve. its often the motor that goes on these and it stops the valve moving. but i cant say for sure without looking and testing really.
I can opt out for now maybe someone else can help you further.
