hello all,
first time poster. i've read all the boiler FAQ's and searched the forum but haven't found an answer to my problem. can anyone help with the following:
i had an issue last winter whereby the HW would come on, heat to max. temp. then turn off again. after 10-15secs this cycle would repeat until the tap/shower was turned off.
i was only living at the house intermittently at this point, and when the cold weather went the HW operated normally so I didn't get it looked at.
over the last month or so, this problem has returned and is now so bad that i get maybe 10secs of hot water in a 3-4min. period. same as before - HW kicks in, ramps up to max temp. then goes off again.
along with this, the CH circuit is playing up. no matter what temperature it is set at the boiler will only fire intermittently for 10-20 secs then it will go off again. a red light on the panel flashes when it isn't firing but i've yet to find the manual to discover the meaning of this.
i spent xmas away so am only just getting round to diagnosing/fixing these issues. i installed the full GCH system myself [apart from connecting the gas and comissioning the boiler] so i want to fix it without resorting to calling in a plumber. i just need a checklist of things to sort through to identify the problem. colleagues say divertor valve, pump or heat exchanger, but that's hardly a narrow field to work with!
reading the other boiler threads, i'm going to start this evening by looking at the divertor valve, but feel free to ask me questions to help diagnose the issue.
boiler is approx. 3yrs old, i *think* it's a baxi but i'll hunt the manual tonight and confirm the make/model in the morning.
cheers in advance.
phil.
