Hi
First off, I'm not a RGI, just a homeowner, and I have a return visit booked with Baxi for after the weekend, so I'm not attempting a DIY repair. But because the problem is intermittent and the first visit did not solve the problem, I'd appreciate any advice from those with experience so that I can give the repairer as much useful info as possible if the fault is not showing when he turns up.
On the first visit, the condensate trap, burner assembly, combustion box door and gas valve were changed. Since then the boiler has tripped 3 or 4 times in the space of a week.
On pressing the reset button, I've witnessed two kinds of behaviour:-
1. The ignition sequence starts with the two normal mechanical clunks occur, but the gentle whoosh of the flame does not follow. This repeated twice, and on the third attempt, the green ignition light faltered and then stayed on, and the gentle whooshing could be heard - it took a second or two longer for the flame to light on that third attempt than I have heard it taken in the past.
2a. On another occasion, the two normal mechanical clunks occurred, followed by a lot of rapid clicks, several times per second (spark generator?). The gentle whoosh of the flame began, but then the boiler aborted the ignition sequence a few seconds later.
2b. On the next attempt in that sequence, the two normal mechanical clunks occurred, followed by even more rapid clicks, and then it ignited with a "thud" and stayed lit.
Does anyone have any views on what all this may mean? I understand if people may not wish to get involved as there is a re-repair booked for next week, but I feel it could be useful for those plagued with intermittent faults in terms of narrowing down which symptoms to highlight or look for if the RGI cannot witness them himself.
