no hot water no heating?

anyone been playing around near gas valve? if one of the little modulator wires comes off it'll stay on min burner pressure setting around 2.5 mbar?????

thay have a min and max gas rate setting, sounds as if its not opening up to full rate, usual burn would be,

hot water - come on full gas within sec and stay high and modulate when temp reached.

ch - come on full and depending on sys temp drop to a lower rate pretty quickly.

if its just a tiny flame from start on hot water demand ie no high fire at all id be thinking gas valve/modulating fault.

maybe temp sensor but id expect it to fire on high and trip out if sensor fault.
