Would you work on a boiler that has no data plate? I went to a faulty Vaillant combi today and I still have no idea what model number it was. There were no manufacturer's instructions either. On CH mode, the burner ignited on high rate for 5 seconds then went on very low rate at about 70c for a minute, then the burner went off for about 5 mins. It kept cycling like that continuously. The burner stayed on full rate for longer in HW mode but behaved similar. I've got a hunch it will be the pump but without any ID and a mulitude of pumps fitted to Vaillant, how do I know which one to risk buying?
 
Dunno mate. The pump had 2 cables going into the terminal cover. One of them appeared to be going to the gas valve. Woild the pump be modulating along with the burner? Im going to try posting some pics of the pump shortly. Does anyone have any other ideas of which boiler this is?
