Hi all,
I moved into a new build Nov 2014 and it was fitted with a BAXI DuoTec 2 33GA combi. From day 1 I've noticed that it has been displaying what I understand to be known as "explosive ignition".
Baxi have been out numerous times to replace various bits and pieces under warranty but they don't seem to be able to solve the issue. I think they replaced the pump, electrodes, valve and some sort of chip (I'm guessing the CPU sort of thing as it required a "reboot" which ran the thing at full speed for about 10 minutes).
After some testing, I've noticed it tends to be worst in the morning when the system has been off overnight. I'm not a boiler engineer obviously but my theory is that gas is leaking into the combustion chamber so that when it starts it's routine in the morning, more gas is present there than should be so the "pilot ignite" (for lack of a better word/phrase) is too big.
I'm getting a bit fed up with this never being resolved and I feel like the guy who comes out must be pretty fed up too.
Any experts here have any ideas what may be going on and why they don't seem to be able to solve it? Am I just paranoid and actually this boom is perfectly normal? It's kind of scary and is enough to shake the enclosure.
Any advice would be much appreciated as I'm worried I'll end up having to replace the whole thing far sooner than I should have to!
Thanks.
