Another query, got called to a suprima 80 l today. Sparking but no gas. Not even getting a little drop on inket when sparking. Not a sniff on burner pressure either. Think gas valve is knackered but phone tech just to make sure. He says measure power on valve, should be getting 240dc. I am getting 190, says replace the pcb. Oh, ok, I thought gas valve, then he gets me to measure the resistance across top and bottom, think I was getting .9k when it should be 4, then top 2, I am getting .5k and bottom 2 3.9k. He now says, this is a tricky one, maybe replace the gas valve. Alright for him to say, now I shall buy both just incase and then be out of pocket a 120 quid either way
