I have a ravenheat 84et. I am getting intermittant hot water and central heating. Sometimes the boiler runs but it does not ignite. Also I have to sometimes turn the hot water tap on and off several times for the burner to ignite. The ignition board, microswitch, electrobe and pressure switch have all been replaced. But still there is this intermittant fault.
Anyone have any suggestions please.
