Hi my boiler is 10 years old, no fault code but sometimes when the warmstart operation starts the water is cold and boiler does not light, then when you leave it its ok later. sometimes water goes cold in middle of a shower. Now I know its not the divertor valve as that was replaced last year and show different symptoms.
My heating I have not put on yet at all until it gets really cold as I like to save gas but the boiler struggles to light when turning the tap on, then later its ok.
No fault code is displayed and the water pressure I have checked and is 1.5 bar. I know this boiler quite well and always check the instruction book for faults.
It was serviced last year, what does it need doing to stop it failing to light.
Someone said to me it could be HE or something???
