Help please.
As above, it wont fire up. It clicks, pump starts as pressure gauge jumps slightly. Fan doesn't start but I've tested it and it's fine. Plumber told me to replace ignition board which I did but still no joy. It works on rare occasions for about 24 hours, but when it dies it's dead forever!!! Same results with both heating and water. I went to remove the right hand flow switch but water started coming out so I re tightened it. Thermistor shows very little resistance. Overheat thermostat seems to start around 45 ohms but gradually decreases(is this normal?). I can hear the diverter valve kicking in when I turn the tap on so I presume that's working. Plumber doesn't seem to want to come back and I can understand why, he's only young, he was at junior school when I bought the boiler. Any help appreciated. Thanks.
