Yes I tried that, thinking it might be a bad connection somewhere of the pcb.Hey gas2fart , what happens when you tap the bottom tray? Phroomph
Even tried pressing parts of the pcb, with insulated instrument.
It didn't make any difference (to my surprise).
I guess no gas is passing through the main burner bit.
But is the fault on the pcb or something else? (in you experiences with this boiler)
