Pilot lights keep going out (Worcester)
I have a Worcester combi boiler which is about 11 years old. It is
under contract with B Gas. Recently it started blowing pilot out. What happens is that if you turn on the hot water (tap or hot water) its works ok for about 5 mins and then there is a clicking noise and pilot and flames blow out. I then have to light the pilot by firing the button 5-7 times. It will work again for about 4-5 mins and same happens again - clicking noise, flames/pilot go out. This happens consistently on hot water. If we use the central heating then it may blow out 1 or 2 times in evening. I have called out Bgas 3 times and they have not been able to fix it. They have changed a thermostat and then a sensor but without luck. They are now saying that the boiler is too old and needs replacing. And CH also needs a power flush to get rid of debris. They say there is no other remedy. Now if there was debris that was causing the tripping then I would expect this to happen more on the CH side rather then the hot water. I would also expect the tripping to be random rather than consistent. I am totally unhappy with B Gas being unable to find the fault and telling me to replace boiler. Yes the boiler is old but it has had about 60-70% of the components replaced in the last 2-3 years. I am paying them 16.75GBP per month and I think they are not putting in the effort to find the real fault. One of the things I have noticed is that when we used the hot water before, it used to get really hot after 4-5 mins and it used to go into a rest mode and started up again after a minute or so. Its not doing that - it just trips now. I told that to the B Gas engineer and he repleced the sensor but it has not made any difference. Is it possible that the internal is not receiving enough air (fan maybe faulty)? I think there must be another reason for all this other than the debris. Can you please give me some advice/pointers as I am going to call out B Gas for the last time. |
