Hi, I have been through the forum and tried to find similar issue, but its always complex. My boiler failed and after engineer's visit he advised that boiler needs replacing as the fixing is not economical! What an advise! He wasn't sure what is the issue and advised so many different 'maybe' things that he sounds like he doesn't know - anyway.
Boiler is Heatline 30 approx 9-10 years old
The symptoms are as follows: The hot water works but only up to warm temperature - not hot like in the past. Sometimes when opening tap (first thing in the morning) the CH sensor LED comes up and boiler stops working, but after approx 15-30s of water running all seams to clear and 40C warm water comes up again.
The CH does not work at all now. Last heating season it was on and off but generally was kind of working. Today, the boiled fires up, is working for 10s, than flames modulate down and the CH switches itself off and CH Sensor light comes up.
Obvious check would be CH sensor, but what is the resistance I could expect from working sensor and what would be the resistance of faulty one?
Perhaps problem is elsewhere and CH works correctly? Why CH sensor comes up when demanding hot water? Please help, any advise would be very helpful.
I think that there is a single component that needs replacing that would cost circa £100 or so. I am not willing to replace all boiler. It would be nice to know few things before another engineer comes to check as the first one I think was a cowboy.
